Grew up on small blocks, and currently have a carb swapped LS3. I have no feelings either way. I love both. However, the AFR Enforcer heads are no where close to a stock LS3 head flow wise. Your enforcers flow about 250cfm@600 lift on intake side. The LS3 flows 300cfm bone stock. Ill also say this with confidence, ive had s built 406 sbc and this LS3. Conparing the 2, the LS3 may be down on torque just a tiny bit on the low end, but buddy let me tell you, pound for pound its faster woth the LS3 than the sbc. And has been more reliable. Plus, with the carb on it i tune it myself so best of both worlds. Thats a solid snall block your building. Good luck with the build
I have a 84 4runner. Obviously it didn’t come with either. But, I chose a LS to start off with. Butttt, then I changed it to a vortec 350. The reason why I switched, is because of the simplicity of a sbc. The minimal electronics to get it running. When I’m out in the desert, I don’t want a computer or an ignition box keeping me from running. A 35$ HEI distributor is all I need.
LS’s can make great power yes. But LS movement is getting old lol. Any motor can make big power with deep pockets. But the LS guys must forget that guy’s dragging in the 60’s and 70’s we’re running 9’s low 10’s back then. I kept my 350 in my c-10. Love it lol. Love this video too 👍
I feel like the real reason guys want to put an ls into their old cars or anything for the matter is because they dont know how to work on older style engines with carbs and timing light degreeing the cam etc the "tuning" part of an old engine. These younger guys literally have no ida to truly work on them so they kust tell their buddies "yeah i can put an ls in and have someone tune it" its easier for someone who wants to try and act like he knows whats hes doing to have someone do all the work for them and then calling it their own.
It's trendy too, when all the hype is LS and LS fest n so on people wanna be in the cool kids group, I've almost gotten sucked in but didn't, people act like the 5.3 is magical they make insane HP and can not be killed... That's just not true, they have a strong bottom end from the factory and most OEM LS heads flow better than most OEM SBC heads that's about it. If they were so indestructible why do people have 4 sitting out back waiting to replace the junkyard one they installed, because they blow up just like the rest. The LS had a 14 year run the SBC had 47! That means something.
Ls still has bottom end and rods u have to go aftermarket on SBC. Heads flow better then he makes it sound. Both are great engines but if u wanna make reliable long term power LS will beat sbc no matter how u bet against it.
@@mikehodgson9149i have a 500 hp 11.5:1 355 sbc in my 68 firebird street car thats been running a mix of 93 octane and vp q16 since it was first built in 2005 and it still kicks ass not many haven't been taken to town by an LS yet unless it was under boost or a had a bottle
😂😂 I’m probably younger than you are bud and I can tune a conventional motor. Ls is just the new sbc. I’ll always love the old sbc but technology wins every time
I think there is truth to your statement. Most people don’t have a clue what’s going on, period. And I am not a fan of those people bandwagoning and acting like know it alls/better etc But EFI for a street car is just better. Better power in all driving conditions combined. Better fuel efficiency. Better drivability. MAYBE there are some applications where a carb shows more power than Efi, but it’s not quite that simple to have a real comparison. VS efi that can run closed and open loop to adjust for whatever random situation you’re in… Add in the natural racing tune ability of EFI… so that timing changes dynamically during a run, or can allow for different AFR’s in different conditions, or even just safety (knocking, overheating etc). It’s just more reliable. The thing that really sets it apart is how good the valvetrain is. Not just head flow, which honestly is only ok. Once you get into aftermarket heads, head flow isn’t hard to find on any good v8 platform. But, the LS has incredible valvetrain stability, with simple and minimal mods. Which means aftermarket heads also can have killer valvetrain stability for really cheap. Not many engines can spin to 8-9k make over 2000hp with stock rockers, just a valve spring/retainer kit, decent pushrods, and a bushing kit. Easily spin 7-8k on factory heads with just rocker bushings, pushrods, cam, springs/retainers. Throw in a cheap $300-400 rocker arm shaft kit and you can spin it up as high as you want-bar maybe a little lifter tweaking. Aftermarket heads same deal or less. And you can get factory valves that are stronger + lighter than aftermarket versions, that will fit in aftermarket heads, new in the box from GM, significantly cheaper than from the aftermarket. The gen V stuff is even more impressive. And as time goes on, the gen v sbc will be the king. Sleeves are stronger in the alu blocks, direct injection allows more power on pump gas. Heads flow killer, valvetrain needs even less mods. It’s crazy to me seeing Chevy fans act like Chevy didn’t design newer and better. The sbc, pg, th400… all are old designs. They’re great still today, but Chevy took what they knew/learned from those and made them all better.
I had a 383 long block assembled for my ‘76 corvette roller cam, roller rockers, Pete Jackson gear drive, 10.1:1 crank wiper, windage tray, baffled oil pan, , Air gap intake, Sniper EFI, Full Hyperspark ignition system, and a few more goodies. I am looking forward to some LS confrontations.
I have bought two 5.3 LS engines in "good condition". Most of everything on them is tired and old. Damn near everything has to be replaced. You are left with a block and heads. Everything else is junk if you want any level of dependability. It adds up $$$$ fast. Unless you're chasing 450+ HP or a race engine, the SBC is the way to go. Also if you buy a Gen 4, you automatically have to buy a $500 DOD delete kit.
I grew up building gen 1 small blocks and they are great engines. The future definitely belongs to the LS engine like em or not. I'm a BBC guy myself..if you're going to worry about cost of swapping or building engines you need another hobby.
I just built a small block S10 on a shoe string budget... Got the truck for doing some work on a 53 Buick so no money in the truck itself... Ended up with a 305 small block out of a 24 foot Bayliner so it's a factory 230 HP engine... turbo 200 metric 3 speed auto for free since it sat on a barn floor for 25 years... Quadrajet came out of my buddy's scrap dumpster... So for gaskets, mounts, HEI distributor... Facebook marketplace shopping for the headers and Hurst shifter setup as bare bones missing covers and knob, shift cable and yoke to extend the driveshaft another inch and u-joints I and exhaust made from parts store bends and Amazon cheap flowmasters.... All in I was at just over $1500 bucks.... If I did an LS swap I would have had that just in parts and a msd controller without any other stuff... And now that it's setup for a classic small block... If I want to go up to a 327 or a 350 or even a 400... It's as easy as unbolt and bolt back in.... Gotta love a classic small block! Good video man!
Loving every second of rebuilding my gen 1 350sbc. Found out my 75c10 has 76 Camaro engine and it’s always fun explaining why my truck sounds like a 70s Camaro lol.
FACTS......everyone kept telling me to put a LS instead of a 350 in my 96 2wd Jimmy........well geniuses, it had a 4.3 so the layout is very similar but with 2 more cyl on the end. AND this way I don't have to notch the frame or other bs. Heck as far as don't let your friends talk you into shit goes.....everybody was telling me to go 383 instead of 350, well yes it is better but I don't want to mess with clearancing the block and small base circle cams etc etc.
305 is better if your running the 4.3 running gear. Makes less torque down low so you don't break everything. Granted a 350 is better. But I'd run some shitter traction tires so you'll burn them off the break everything else. Just watch your rpms and don't let it grab traction/ shock load until you have supporting mods for the rear to help minimize your load so you don't completely just shredd the rear end every time. Or drop you in a 2500-3500 rear end and let it eat. Just my 2€.
Orrr you can find a 400 sbc and do the same shit and have WAY more torque.Bye bye LS.I love putting these LS guys in the places with my 406.Simple torque and adjust my rear view mirror.Oooo Oooo I just made over 500 lbs of torque on all motor.Simpke science.Great video thanks man.Love it.
Here's my two cents - SBC is awesome - great engines. One of the best ever made. IF I were going to do a SBC it would be a well built 383 with good flowing cylinder heads and a not so lopey cam, headers, big single exhaust, on and on - and I would probably run someone's FI system and a good electronic ignition. But you can purchase a good used and running 6.2 from an Escalade or Tahoe for about $3K - that makes 425 or so HP out of the gate - and use a factory or aftermarket ECM - headers, large single exhaust....and you will have a very nice and drivable package that is very reliable. I don't see computer controlled drivetrains going away any time soon. The reliability, ease of use, the lack of regular maintenance or "tuning", and fuel mileage are all desirable features in my opinion compared to an old school SBC. These two engines have their place - but if I had the choice I would choose a FI LS every time. My opinions only.
Going through an L31 for my 71 chevelle right now. Intake, LS 6 springs, comp retainers, offset keepers, summit cam, a little bit of porting and keeping my old quadrajet. Should have it going by end of week... way cheaper then LS which would take a month or more...
I like em all, grew up on Gen 1-2 SBC and now messing a little with the LS Gen 3-4 engines. But I have to say junk yard LS swap is cheaper. We just swapped a 3rd Gen Camaro. We got a 5.3 for $600 with harness, ECM, accessories and all. We reworked the harness so the stock 5.3 ECM could get 12 volt power from the battery and a switched ignition source (old HEI wire). $50 ICT SBC to LS swap motor mount brackets. We did cam and springs for $600 and mail order tune for $300. We used the stock intake (which flows really good), fuel rails, injectors, and even the stock truck exhaust manifolds, etc... Runs low 12s in the 1/4. Car already had a TH350 in it so that made things easier. Good thing about it, if it ever blows up, go get another $300-500 5.3 and just swap it out. Them LS motors already have heads on them that flow like a SBC aftermarket head, I do not think you are aware of how well those stock LS heads flow. So basically we did this swap, with a cam, for less than the price of your heads.
You can see here the stock 799 head almost matches AFR head in flow and this is a stock casting head, and even the lowest flowing stock LS head does not fall that short. AFR 195 Enforcer head flow .200 = 133/104 .300 = 188/138 .400 = 226/158 .500 = 250/186 .600 = 251/197 706 LS Head Flow (one of the lower flowing LS heads) .200 = 126/89 .300 = 180/126 .400 = 213/158 .500 = 220/180 .600 = 231/193 799 LS Head Flow (one of the better flowing LS heads) .200 = 142/98 .300 = 193/133 .400 = 230/160 .500 = 243/175 .600 = 248/185
I was contemplating going LS because the internet was making seem so cheap easy to. After doing some research on everything I’ll need to make it reliable and have the power I want I’ll be just about double the price as a crate sbc stroker. I went that route 496hp 510tq
A lot of people who push an LS swap forget to mention the cost of mounting, exhaust, ignition and induction.... They are a great platform, but they aren't always the most cost effective for a swap
The reason everyone used to swap in sbc is the same reason people put in ls engines! They put them in everything and had good cross platform unlike Ford constant changing. I just went through my son's sbc and overall costs would have been cheaper to buy a 6.0l ls and spend a couple grand putting it in the 3rd gen. Why cause the ls is the new 350 and has newer tech and able to take high lift cams and out the box the lower end can take much more abuse oh and most important standard 350s aren't everywhere like when I was a kid. When I was 15 I got a running 350 for 100$ to put in my firechicken.
I got a 78 Z28 with a 355 ci, Brodix Heads & high rise intake, Lunati cam 640 lift, 264/270 duration @ .050, full roller, solid lift, 950 Holley HP, Bilitt crank, Bilitt rods, Manley. 030 over flat tops, Moroso oil pump. Naturally Asperated. IT SCREEMS!!!!!! No LS for me😅😅😅
Ive been on the same page as u and preaching to people that go on and on and on about the ls and it is a great engine but the small block is the best bang for the $buck$ hands down.
Yup, agree 100%, I've been road course tracking a 93 Camaro for decades, as the newer stuff was getting faster, and I was having trouble running with them, couldn't quite keep up with the big dogs anymore, the boys kept saying you gotta put an LS in it, so I built a long, long stroke gen 2 LT1, 13.5/1 compression, Crower crank and rods, AFR heads with a little extra work on them, my own special grind cam Comp did for me, produced 640 lb/ft of torque on the engine dyno with a carb, in the car I still use the stock LT4 fuel injection intake, all on 93 Sunoco, I am now whippin the piss out of every one of them, one of the fastest cars on the track, this thing is an absolute track monster, built the engine in my street car to the same specs.
Not even a Chevy fan but this was an excellent honest video. I hate when someone says they got an LS because they are so reliable, how many small block Chevys do you see broken down on the side of the road, thats nonsense.
Nearly every single one at 250,000 miles. Ls however is a totally different story. I build Ls. Sbc and bbc. No comparison in a sbc and an Ls. I’m building a roller bbc 10.5:1 compression and it won’t keep up with my wife’s mild 6.2. Also this video uses the worst 4.8 head made in comparison. Afr vs stock ls3 head. Ls3 head wins big
Just my 2 cents ls engines are way to hyped up. Yes tge did fix some problems that the first gen had and are stronger but they have there own problems. Never seen carbon built up in a first gen intake but every ls you take apart the intake is full of carbon and oil.
❤I've been saying this for ever. This was the best break down ever. I'd get paid subscription from you. My buddy just bought a Nova with a Blueprint 383 and Sniper and it's fast fast. Few of the guys have built 6.0 ls with allegedly 600+ hp and they are all saying something is l isn't right. The 383 feel way faster.
Awesome video. I wish I saw it before my ls swap. I was going to redo the original motor but it was only a 305. I probably should’ve taken the money got a 350 punched out to a 383 n had been better off but wats done is done. I will do that on my next project tho.
Throw some 9:1 pistons in it and add boost. I did and made 1000whp reliably all year went 5.80s like a bracket car in a full weight belair and put MANY turbo ls 6.0s and 5.3s in there place
Misinformation. Ls not for everyone but if you want to hear from someone that is sober and knows engines look up Richard holdner. He is not biased and has a Dyno run to back up every engine combo he messes with
I have built both, in fact my newest build is a 5 3 in a S10 with a small cam(ss2). Honestly, I prefer the SBC. No hate on the LS, but it is overhyped with much of the info being regurgitated from what they heard, from LS fan bois. No, your cathederal port 5.3 is not going to build 550HP with just a cam. In fact, most will struggle to make 450 HP(there are exceptions). Sure, add a couple of cheap Wuhan war whistles, and you can build a monster, but the same can be said for the SBC. For a cruiser or driver the LS is pretty awsome, makes decent horsepower and will return good mileage, also start at a flick of the key, but if i want NA performance, i will build a SBC over an LS any day of the week.
Just want to add. 600+ capable off the shelf heads are available for under $3000 for a 23° SBC. Look to spend more then $5000 for 600+ hp capable rectangular port LS heads and chances are you will be waiting a while. A built shortblock to support either will both be equally expensive. Bit become original and build a traditional old school engine, the LS is pretty much played out. Again, no hate o the LS, it's a great platform.
I agree, I always get frustrated with "LS or bust" guys, even had one try to tell me a 6.0 was better than a big block to build to high power.... An LS is great, particularly for a boosted application, but as far as N/A hp dollar for dollar, it doesn't out class the sbc enough to justify the added cost of a swap. Small blocks keep things cheap, simple and fun. Honestly if I were to build a modern n/a motor, I'd do a Gen 3 Hemi with stock Apache heads that flow just as well as ported T.S.P gen V LT4 heads on intake and more on exhaust....
@7000U9ZHIFT Max effort vs max effort both engines would be in the ballpark of each other given both would have the best heads you could get along with all the high end components to go along with it. There's no inherent advantage to either platform if you throw the parts catalog at them. Besides, if you're going max effort, a Ford, a mopar or anything else you can squeeze a lot of displacement out of can make huge numbers and be almost indistinguishable for one another....
Listen man you just confirmed everything I argue with my buddies about on a daily basis, I respect the LS world but I will never turn my back on a sbc!! Power to the dollar and reliability you can’t beat em!!! And guess what?? I’m a foxbody 5.0 fan but I’m serious thinking about putting a 350 4 bolt main from like a 98 vortec motor in my Fox 😂
Priority cam oiling as opposed to main oiling in the LS platforms coupled with oiling pooling due to poor drainback in the heads scares me on LS motors. And I own an LS3. Seemingly the SBCs and BBCs never suffered from starving in sweeping left hand corners or oil cavitation, while the LS suffers from both. Due to the drainback issues and a vane rotor oil pump. Either platform will perform flawlessly with a dry sump but that's 6000$ or more either way.
Afr enforcer heads flow 251cfm @.600 lift stock ls3 823 castings flow 296cfm @.600 stock yeah the intake cc runner is bigger but at the end of the day the head is still recommended for a 4” bore point being I can find right now on eBay or Facebook marketplace ls3 heads for $500-650 a set! Because everyone is selling those to buy more expensive Frankenstein heads or Mast heads when the stock heads are amazing as is. You speak of cam swaps and springs. BTR makes a truck Norris NSR (no springs required) that makes 430 hp on a stock headed stock intake 5.3 truck motor. Yeah ignition boxes are expensive but not if you look around I picked up a msd 6014 for $250 and can use the stock harness to plug and play. Hell most people use the stock ecm anyway that you pull with the motor. You say $200 manifold for sbc, I bought a single plane mid rise for my ls for $140 and it would wipe the floor with any sbc $200 intake and would be on par with air gaps because ALL Ls intakes are air gaps since you must block off the valley cover. $300 for engine mounts and trans mounts? You can get ls motor mounts for $50 and if you use a th350 or th400 you can use a 6.0 ls flexplate to mount the motor to the torque converter drive and go. I’m not saying this to bust your balls it’s just I’m building a 355 and have sunk so much money into it to make what a 5.3 or 6.0 would make effortlessly. Those afr heads won’t flow anything without their $400+ intakes like the 4812 or single plane variants. That cam you put in that sbc it better be a flat tappet because if you’re talking roller and trying to make any power then you’re going to be at $600 or more out on lifters, the cam, and now new springs unless you have a newer factory roller block which then still you probably want to get new parts if you care about your motor at all. All ls motors have roller cams and pretty nice lifters and if those lifters aren’t good enough ls7 lifters are cheap and plentiful $270 on Amazon and eBay.
Love the video and agree with you but depends on what junkyard engine your getting, an 05-06 5.3 H.O. L33 has 330hp stock aluminum block and comes with 799 heads which are the same as ls6 243 heads you can watch a TH-cam video on how to port them, install a no springs required BTR camshaft build your own engine mount plates for like 20 bucks and butcher a wire harness together and have a 450hp + ls swap for less than 1500 bucks
Been building small blocks and big blocks my whole life. Drag cars and everything in between. Let me say this, tuning a carb is so easy compared to tuning LS swap. Anyone can tune and work on an old engine but good luck learning HP tuners and dialing that in. If your old and not computer literate stick to the old stuff. power is just a product of how much $$$ you spend. Thanks for the video!
SO I HAVE A 1995 C1500 CHEVY WITH THE SBC 350 AND NON VORTEC SO TBI AND MY FRIENDS BEEN TRYING TO GET ME TO SWAP IT BUT, ! IS EXPENSIVE, 2 I LOVE MY 350 RUNS LIKE A DREAMS AND ITS GOT SOME TORQUE, SHOULD I JUST KEEP MY 350 ?
@Pendragon69608 It really depends on your goals. If you don't care about making gobs of power, you can achieve 250 to maybe 300hp if you swap the cam, intake and run a carb... There's not a whole lot of potential in swirl port L05 heads. If you want something that's fun to drive with 350-400hp, throw some parts at it. (Vortec heads or a budget aluminum set, along with cam, etc.) If you're planning on making piles of horsepower (500+hp) Either pull the 350 and swap a 5.3/6.0 or big block swap it.
Both great motors. You've got to love the LS series top end. I'm currently putting a GM crate SP383 EFI into a 72 Blazer just because we don't want to deal with all of the conversion parts.
In a vehicle that never had a small bock, stock for stock, the LS will make more power for only marginally more money. Assuming you get your parts from a junkyard, you’re 600 for engine and trans on either one. Both options require the same components to run. This guys added cost of the intake and carb for an ls and the coil controller is irrelevant, because there is no real reason to run a carb on a modern fuel injected engine. Either option you have to either buy mounts or fabricate your own. The additional cost from the LS comes from buying a computer that has had security deleted, or buying a device to do it yourself (which costs $80). Is the sbc simpler to swap? Yes. Is it a better choice? No. I have no hate for the sbc, but I do get tired of people who preach how much greater the sbc is over the LS. Those people talk about how these people only do it because they don’t know how to work in carbureted engines, when they only do sbc swaps because they don’t know how to work on these modern computerized engines. Neither option is better than the other. It all depends on application
I swapped a LM7 into my 94 s10. It's my daily driver. I started with a good running and driving silverado for a donor. Body and frame were shot. Used as much as I could from my donor in my swap. It didn't cost me a whole lot for the swap because I already had my donor vehicle. LS swaps only get expensive if you go all out. A stock motor swap is not that bad.
Green question but I need help. I have a LC9 which is a 2007 5.3 L I’m gonna put a sloppy mechanic stage two camshaft in as well as LS7 lifters and 1218 springs in 799 ported heads. I’m kind of leaning towards using stock ls1 pushrods but if I was to upgrade them, what would you recommend? Also, I’m considering on changing the pistons would you recommend changing piston rods as well? If so, do you recommend any of that are as strong or lighter my goal is 500 crank N/A.
@Speakertweaker-tp4em Stock rods are quite good, I would personally put A.R.P. bolts in the big end (machine shop can do that and resize them) As far as pushrods, I don't think there's much to be gained strength wise unless you plan on running it hard up to 7000+. If your springs are really stiff, the stockers can flex... I like trick flow pushrods for any hardened sets, but any of the upper end mfgs have pretty good products
@@t.n.tgarageandperformance awesome thank you for the reply. If you don’t mind, I have a few more questions are stock LS1 rocker arms OK for my application. The engine is going into a 2002 Trans Am six speed manual. Also, would you change the Pistons or is stock OK? What? If I should upgrade piston what would you recommend? Also planning 6500 rpm max
@Speakertweaker-tp4em Factory rocker arms will work well, I've seen many factory ones live happily at 7k rpm, just make sure the trunnions aren't sloppy from excessive wear. Stock pistons will get you around 9.1 compression with 799 heads, so if you want higher compression, go with a flat top piston. Depends on your budget as far as what's best, Speed Pro, Wiesco are both good budget pistons, SRP are great for much more money. Same goes with budget on type of piston, Cast/Hyper are fine if you don't boost it or spray anything over 100hp (given good fuel and proper timing, personally I wouldn't spray on hypers) Good forged if you want to do all of the each, Wiesco actually has a pretty affordable option for forged pistons in their Tru-Street line. Now, if you don't care about upping compression, run the stock pistons, they'll hold up to a hell of a lot
Love it! I paid more than I should have for a 327 never ran it just took it to my local shop and I’m going to put it in a 78 nova that originally had a 6cyl. I’ll be less than 7k buying car and building motor I’ll obviously have more as go but that will be driving on the road price
Will this 400 horse engine survive in a BMW E36 drift car for more than 10 events If you're not trying to compete just fun days? Trying to decide between small block Chevy swapping or just turboing my iron block M50 in line 6
I've got a stock bottom end with the exception of ARP bolts in the rods. I would run an ignition box that gives me a rev limiter if I used it for drifting, but I would trust it. It's really 6 of one, half dozen the other, the M50 is still plenty capable and you wouldn't have to swap everything.
Yeah when you make the math on your side ya can make it sound great. 600$ 6.0, 150$ for a inline pump and a rubber line, 30$ mounts and chop down your own stock harness. Throw a sloppy stage 2 and pac 1218 springs you will make just as mush power with a stock block stock heads stock intake stock injectors. Oh and I’ll daily drive it through the winter sub zero temps with no issues
I'm all about a budget swap, but guys that can do that kind of swap are more the exception than the rule. That's why sticking with the sbc is better for most people
I wouldn't even consider myself a beginner mechanic more of like a parts changer. Lubetech so I would much rather stick with the old school motor in my 84 k20 then to try to do an LS swap and run into a million problems. I have no idea how to fix old school motors doesn't have computers which I hate. If I was 10 times better mechanic I would consider an LS swap but it seems really complicated
There's a reason you can find so many "half" finished LS swaps in your choice of platform on marketplace....people think they're dummy easy and that they can do it too....only some can.
The dollar for dollar comparison is not an exact comparison. Prices vary so much for used stuff and depending on how savvy a person is one may spend apt less to get something done. If starting from nothing I’d go LS and a mild cam in 6.0 and make 450ish. If you are swapping from a SBC of course is not gunna payoff depending on what you want. But for overall drivability an LS will make more power and be more streetable at higher power dollar for dollar.
The ONLY problem I have with a traditional SBC OVER the LS is the fact youre not coming CLOSE to the performance capabilities of a STOCK iron block 4.8/5.3/6.0 without a Dart Little M or such aftermarket aluminum block to make a MASSIVE cubic in. Stroker small block and thats not CHEAP! There's not a SINGLE Stock bottom end 2 bolt main 400, 4 bolt main or otherwise SBC that's EVER reached 1400 HP......the iron block Vortecs have.......not having to spend 2500 dollars on a stroker kit or forged rotating assembly is a GOD SEND for building an engine. Camshaft and Turbo kit and you can reach any sub 1400 HP level you want with a 6.0....YES it will make passes. YES everything breaks all racecars do. YES your SBC can make 600 HP or 800 HP but with as few parts and as little money spent? Not gonna happen.....you can run a carb on an LS too..... it's called the SUCCESSOR for a REASON! the fact it has 6 bolt mains is already the main reason it sticks out above the rest of the competition.
@ConcussedGaming I absolutely agree that the LS architecture is far and away better for high hp. The sbc is good for 400 hp without going 4-bolt or doweling the main caps, making a very viable option for better bang for the buck up to that point. 450-500 hp and above, the LS eclipses the sbc quickly in the most hp per dollar
If you look at 1000cc motorcycles back when they transitioned to fuel injection, they had the same fuel consumption with slightly less HP than the previous year (carbed) with the same engine. Tuned right a carb is just as efficient and you can tune it yourself when you do changes to the engine. FI is for convenience of not tuning for stock engines. You do get a little better off idle throttle response, easier warm up, less stalling on extreme grades...at the cost of complexity and resources to keep it going. I don't think fi is the way to go for hot rodding or performance applications. A carb just hits harder. Ride a fuel injected bike vs a carbed bike of the same model and then you will see.
I ls shaped a chevelle it has 500 hp I get 16 mpg cruising about 5 more mpg and 100 more hp that's why I did it to be honest it runs extremely reliable and puts down great hp.
I disagree with your crazy statement sir!!! I put a spreadbore Edelbrock on my 460 because I firmly believe the best way to make a Ford run right is to put some Chevy parts on it!!! I'm also using an HEI style distributor just because......
LS only makes total sense if youre on a tight budget and want the best engine for the least amount of money. However most of them i see are crazy aftermarket block builds with stroker cranks. People have been building sbc's like that for decades and making north of 1500hp so if you have to spend 3 grand on an lsx block you could buy a Dart block sbc for less and start there. Point being if youre spending 10 grand on aftermarket parts the platform doesnt matter anyway just choose what fits best in the car.
So you're saying that the square body that i spent 30 grand on with a SBC 350 with aluminum heads and Edelbrock intake and long headers that is sluggish off the line would make more sense to keep than LS swapping it? 😢
I went behind my wife's back and bought a junkyard L33 for $900 because I was disappointed when I discovered how sluggish this thing is and now I have to build it up. My wife isn't gonna be happy with me. Kind of wishing that I didn't buy that LS and should have spent money to beef up this 350
Depends on why the 350 is sluggish, could be rear gear is too high, poor tuning or internals that don't let the top end perform to its potential. Building either is going to cost $$, but you're money ahead with the 350 to build off of
Im an old timer. Small blocks were all I ever had. Price and convenience of a sbc is so hard to beat. I wouldn't know where to begin to stick an LS in a project car. Never had one to take apart. Knkw nothi g abiut necessary harnesses and control units. All costly I'm assuming.
@rogerdonoho4924 LS swap components can get costly.... As far as mechanically, they're simple enough and very strong. But, a sbc will always be the most cost effective up to 400 hp I believe
808 350 block rings scat stock crank . A take out zz4 cam picked up vortec 906 heads with a air gap intake on cl 600 bucks .reused my old 750 holley. And oh ya bee hive springs comp + .050 locks and retainers same headers as before. 350 to 400 hp easy under 2 grand .

Ls = Oil problems !!!!!, Gen 1 SBC = no problems..... LS = has 4 big bolts per Cyl on heads, SBC = 5 big bolts per Cyl..... no problems !!!!! ... Generation 1 small block Chevy engines are more reliable and give you the best bang for buck and not to mention they do make power reliably if you know how to do it. 💪😎 💯% 🇺🇸
Ls = 6 bolts for the main bearings which is arguably more important vs 4 at best and the block doesn't come down as far leaving your bottom end weaker stock.
@jesseeaston1687 I wouldn't say they do nothing but id argue the way the block comes down farther the meet the main caps is the more important part, sbc just isn't nearly as strong in that area especially the 2 bolt mains. As far as the head gaskets going under boost Idk, never ran boost unfortunately (too much money and never end up pulling the trigger) I always build NA. Are you talking about gen 4 + DOD lifter issues as far as the oiling problems go or are you talking about something else? If gen 4 then idk, I really am not a fan and prefer gen 3.
Well you tipped the scale, ive been going back n forth what to do, i have a tierd 1976 block 350 in my 92 c1500 hotrod truck that froze n popped a block plug...is it cracked? But it is on a tierd tapered .030 bore but i have a good 88 4 bolt main roller with a tierd stock bore in my cellar from my old truck. I found some .030 sealed power .125 dome hyper pistons for $211 (the dome is because have heavily worked over 76cc heads, those pistons have a 9.35:1 with 76cc so would still keep me above 9:1 with the valve de-shrouding) anyway redline said $260 for bore and finish hone, crank and rods seem fine prob take crank to work and polish it on the lathe with dynabrade pipe polisher and toss arp bolts in the rods with the usual diy mods or reuse my old rods that already have arp bolts so for around a grand i should beable to have a better than stock fresh bore 355 or find a 5.3/6.0 and swap it in... I would have to do buy schoenfield obs LS swap headers that are $400ish and upgrade my fuel system and deal with the ecu headaches or do the whole carb swap deal, i can say the Qjet on a 5.3 thing isnt nuts it sounds awsome! They are my favorite carb only carb i like better is the holley 4165 The 4165 650cfm mech secondary double pumper Qjet replacement is the goat street 350 carb imo. I had The 4175 vac secondary version also it sucked donkey dicks. I had aodified 800 qjet for years but it really did not like the duration and overlap of my cam and the original torker just aggravated it, it made great power but ran horribly rich all the time and about 8 mpg i tossed a cheapo used 600 edlebrock on and it ran beautifully great drivability still had lumpy idle but didnt burn my eyes and mpg went to around 14ish but a noticable loss in top end sack, but twice the fuel economy said lets roll with this for awhile. But short story long im just keepin it old school. I also have a nice 95 mustang gt (last year of the great 5.0) i want to make less slow so fresh 5.0 shortblock and AFR 185 enforcers howards cam and any good intake i can find thats not $1000 so i can get Maybe 350-375 hp hopefully...so every dollar i save is another dollar i can spend on that engine build and being a regular ol blue collar working jerkoff every last dollar is needed.

THANKS FOR THE VID. I RESPECT YOUR BREAKDOWN. GOOD ANALYSIS. WHICH WOULD YOU RECOMMEND FOR A JEEP CJ ENGINE SWAP? (no insults please. Its all I can afford with all the baby boomers hoarding the muscle cars). I HAVE AN ‘85 CJ7 AND WOULD LOVE TO PUT A V8 IN IT. LS SEEMS COOL BUT ITS HARD TO LOCATE ALL THE COMPUTERS IN THR SMALL JEEP. I FOUND A 350 OUT OF AN ‘86 C60. ITS COMPLETE WITH SM465 TRANNY. $750. LOW MILEAGE ENGINE. YOUR OPINION? ANYONE.
Nothing wrong with any jeeps imo, I've built several myself. If you just want to get it running and have fun with it, I'd recommend the 350/sm465 combo. There's plenty of mount kits out there for old CJ's. You'll probably have to get driveshafts made no matter which way you go unless you have the jeep trans to bolt to the engine
As long as the block is sound, you can build a decent 383. One thing to keep in mind is that the power limit on a 2-bolt main is 500 ish hp, the caps tend to walk in stock form at that point. I've seen plenty of 2 bolt 383's at 400-450 hp do just fine
@@t.n.tgarageandperformance Since its from a C60(?) heavy duty flat bed truck I’m hoping its a 4-bolt main. Thanks again! I think I’m gonna try this 80’s sbc. I can’t even find an LS because all the mechanics are buying them and hoarding them (like toilet paper) from the junkyards.
Ok, now lets be HONEST. What distributor are you using in the L31 sbc? Because it didnt come with one that will work with a carb. Are you going to use a 300,000 mile hei thats all worn out and so loose it doesnt hold time, and pushes oil past the bushings, or are you going to spend several hundred on a new MSD setup? O, right. Are you REALLY going to run a 300,000 mile quadrajet with worn throttle shafts that make it leak vacuum and impossible to tune, or are you going to run the same new holley you would put on a carbed LS? O, right. Do you really need to spend $400 on a LS carb intake, or can you buy a used one for $200 all day long? O, right. What happens if you spend a little more on a 6.0 instead of the 5.3? O, right. Who is doing your machine work on the sbc? You, with a dingle ball hone and a dewalt cordless? Is quality maching work on your " brand new " sbc free where you live? O, right. Do you really care if your bottom end is brand new in an LS when we all know most of them go several hundred thousand miles without fail? O, right. What happens if you buy a used msd for your LS? O, right. What happens to the price of those afr's if you want to spin a litte more rpm and make some more power in the future? O, right. It doubles. What happens if you are putting your sbc in a third gen camaro or a vette with low hood clearence and cooling issues with hot small blocks? Might be nice to have that fuel injected LS ...You make some valid points but you miss two for everyone you hit.
An L31 will easily run over 200k miles along with the 5.3/6.0 I used a new $100 dollar hei from summit, carb rebuild and bushings are $80. Had the crank checked, rods resized and arp bolts put in for $275. Bores were square, so I honed it. Aside from the carb being used, everything else was new. Now, you can pontificate all day about how to make an LS swap cheaper, but even if you average every price on used stuff, your argument doesn't hold water. Like I said quite a few times, getting a sbc to make 350-400 in a vehicle that already came equipped with one will be simpler and cheaper than swapping in an LS.... I've stated MANY times, the LS gives greater returns on hp per $ at 400+ and that the architecture is FAR superior to the sbc. My point is that the sbc is not dead for an easy build for guys who otherwise would be misguided into an LS swap when their hp goals aren't that high.
If I had a dollar for every L31 I've had to rebuild because it was run too long with a cracked head, I could do a dozen LS swaps. But, I'm not your average guy. They are a fine motor, but the early LS is better in every aspect. If you want to make the cut at 400 hp I kind of agree with you, but most people doing LS swaps are after much more than that, in my experience. Good luck with your $100 summit hei. I'd recommend carrying a spare ign control module in the glove box, and don't expect a vary accurate timing curve with it no matter what weights and springs you put in it. Been there done that. Never again.
Im glad to hear someone else feels the same as me. Im sick of hearing LS this and LS that LOL. By all means they're great engines but so is a SBC. I just enjoy the simplicity of the SBC and it'll make plenty of horsepower for the street. Im sure this video made the LS fanboys go make sweet love to their LS's and wisper sweet nothings into its intake LMAO. If you cant make power out of an old school SBC you dont know what you're doing.
I like Ford and Chevy. And I don't go with a platform just because I'm that guy. I put the engine based on what's going to be best for the vehicle and what I want to do with it. I've got a 91 GMC Sonoma. Going to put a 5.7 Vortec LT1. Got it out of a 96 suburban. Good engine. Just a little bit down on compression on cylinder #1. Got it for $200. Going to do all the usual stuff. 30 over. Forged pistons and rods. Lunati bootlegger cam. Some nice heads. Air gap intake. Street strip carb. Simple. Cheap. Going to pound off like a muffukker. Plus. Cammed out small blocks sound cooler than an LS. But if I have a Corvette. LS is the obvious choice. If it's a Japanese mini truck and want to do a v8 swap. Obvious choice is a small block Ford. Because it's narrow. Distributor is in the front. Blah blah blah Ford stuff. Everyone would be better off if they forgot about all the brand loyalty BS. And just put whatever engine is the most logical choice for what they want to do. Weigh your options logically instead letting the brand/platform loyal bs make their decisions for them.
All valid points until you leave the carb world and go fi. Script flip GM didn’t offer a good FI option from the factory. TB is very difficult to tune, vortec fi is garbage, aftermarket fi is going to be in the thousands.
Yeah burnouts and donuts are cool. If you have a tire sponsor. But they don’t prove that it’s fast. Not to mention those low profile lowered vehicles spin tires cause the suspension is all wrong.
The issue you run into on alot of the engines is no one does the cam bearings they put a new cam in and redo everything else. It'll hold together for a bit but what ends up happening is it spins the bearing out on the cam. Cam breaks in the block and trashed the whole engine except a few misc things. Had a buddy build 3 of them 1000 HP turbo 5.3s blew threw a lot of money. Took him 3 engines to learn that you can't cut corners if you want it to last.
Yeah I love both but you went the most expensive route on the LS. You just get one out of a wreck harness tranny everything cam springs especially if you go for a 6.0 and you now have fuel injection more power and a strong bottom end. Most haters are just afraid of wiring to be honest.
I 100% agree with people not liking them because of wiring involved to run a fuel injected LS, I've seen many swap projects abandoned and sold, most likely because of that very reason. Is a sbc better than. An LS? Not in a million years... But for what most people are looking for performance wise, a small block is very capable for reasonable money and simplicity, given the vehicle had a small block available at any point.
I have a daily driver 2010 camaro Lsa conversion LS3 makes 900whp daily with air and heat. Show me a sbc that will do at least the same! Or help me understand . Because I know no-one with a sbc with those power levels reliably.
With all due respect, you missed the point of the video. Sure, if you take a car that already has a LS platform engine, nobody in their right mind would swap it for a sbc. The point is, N/A for N/A in an older vehicle, (that was made with a sbc) it makes more sense to build a small block to 400-500 hp than justify the added cost of an LS swap. Of course, when boost comes into play is exactly where Gen III, IV and V motors shine. As far as a 900whp sbc, it can be done reliably with a doweled 4 bolt and a quality rotating assembly. But no one would build that when the LS is there for those kind of power levels
@@t.n.tgarageandperformance either way cost is in direct proportion to expectation. It would be interesting to see a 23 degree head 350 hang with a gen 3 lq9 with a set of 243/799 heads and decent stage 3 cam. Carb or f.i. Dollar for dollar. I prefer the LS platform but wouldn’t bash sbc .
You’re making those numbers because of the supercharger and other components. Put a supercharger on a built sbc or big block, those engines may make even more power safely.
Why do ppl throw around dyno numbers like they mean everything. Dynos numbers can lie or be manipulated. If you really make 900whp. (Im not saying you not) you will run 9.60s or close to it in a 1/4 mile in that car. Personally took a afr headed 383 in a g body regal full interior. Made close to 600 on motor. Hit it with a 300 shot. Went 9.91 that was only about 900 at the crank. And yeah it was street driven. No its not going to be more efficient than a ls. But apples to apples cubic inche to cubic inche it can make the power. Dont forget you are comparing a 23 degree headed motor to a 15 degree. Imagine if you did a 18 or even a 15 degree headed sbc. Numbers would be crazy. (Since we playing a numbers game) Ps been apart of a team 4.51 in a 92 mustang with a procharged f1x afr 245 406 sbc 30 psi of boost. Lol made 1600 on a hub dyno with 26 psi of boost. Its a 4xx sbc 23 degree headed chevy 2 local in michigan. Car gotta be running 4.20s 4.30s. Point is sbc can make power and do anything a ls can except get mpgs (gas mileage) lol
We have a 88 Silverado that came with a tbi 350 i swapped it out with a smaller 4.8 with a mild cam. Picked up almost 2 seconds in 1/8 mile. I think this guy is drunk.
You took out an engine that made maybe 210hp and replaced it with one that made 275hp (stock) then cammed it and gained 2 seconds... Wanna pull anything else out of the no shit pile? You also could've thrown a cam, vortec heads, intake and carb on the 350 and accomplished the same thing without needing to spend anything on motor swap components
@mkfarmer68 if someone is dead set on fuel injection, then yes. But, installing the 4.8 and tuning it also costs money, and that's my point. Dollar for dollar at the hp level, the LS has no real advantage cost wise. Of course, that 4.8 will eclipse the sbc in higher hp gains (400-450+) per dollar. But if a guy already has a sbc powered vehicle that wants 350-400hp for the best bang for the buck, it's easier to build the sbc. Not everyone wants to ls swap and sometimes get misguided into thinking that's to only way to make power
@@t.n.tgarageandperformance absolutely wanted to stay efi. I sold the original engine which cover most of the extra cost of LS swap. It’s also a 16 year old girls daily
@mkfarmer68 I totally get the staying injected then. I put the 350 in my son's 86 c10 with a Holley 670 and wanted to pull my hair out a few times getting him to learn how to run it
I agree, it's more 375+, 400-ish with good tuning and a better intake like an RPM air gap. 450 would be achievable with much more cam (which is roughly the same price as any other roller.) I don't doubt your engine made 550, my buddies old Camaro built in the mid 2000's made 496 who with a fast 90/90, old lingenfelter heads and a t-rex cam

He spoke the truth when he said don't let your buddies talk you into s***
Grew up on small blocks, and currently have a carb swapped LS3. I have no feelings either way. I love both. However, the AFR Enforcer heads are no where close to a stock LS3 head flow wise. Your enforcers flow about 250cfm@600 lift on intake side. The LS3 flows 300cfm bone stock. Ill also say this with confidence, ive had s built 406 sbc and this LS3. Conparing the 2, the LS3 may be down on torque just a tiny bit on the low end, but buddy let me tell you, pound for pound its faster woth the LS3 than the sbc. And has been more reliable. Plus, with the carb on it i tune it myself so best of both worlds. Thats a solid snall block your building. Good luck with the build
I have a 84 4runner. Obviously it didn’t come with either. But, I chose a LS to start off with. Butttt, then I changed it to a vortec 350. The reason why I switched, is because of the simplicity of a sbc. The minimal electronics to get it running. When I’m out in the desert, I don’t want a computer or an ignition box keeping me from running. A 35$ HEI distributor is all I need.
me going with SBC because i work in tech and i specifically want a non sensor'd, no computer, no nothing car that is all linkages.
LS’s can make great power yes. But LS movement is getting old lol. Any motor can make big power with deep pockets. But the LS guys must forget that guy’s dragging in the 60’s and 70’s we’re running 9’s low 10’s back then. I kept my 350 in my c-10. Love it lol. Love this video too 👍

Hell yea. I kept a simple 350 SBC and i supped up that mofo on my c10. Cheaper and a lot easier to work than any LS engine

I feel like the real reason guys want to put an ls into their old cars or anything for the matter is because they dont know how to work on older style engines with carbs and timing light degreeing the cam etc the "tuning" part of an old engine. These younger guys literally have no ida to truly work on them so they kust tell their buddies "yeah i can put an ls in and have someone tune it" its easier for someone who wants to try and act like he knows whats hes doing to have someone do all the work for them and then calling it their own.
It's trendy too, when all the hype is LS and LS fest n so on people wanna be in the cool kids group, I've almost gotten sucked in but didn't, people act like the 5.3 is magical they make insane HP and can not be killed... That's just not true, they have a strong bottom end from the factory and most OEM LS heads flow better than most OEM SBC heads that's about it. If they were so indestructible why do people have 4 sitting out back waiting to replace the junkyard one they installed, because they blow up just like the rest. The LS had a 14 year run the SBC had 47! That means something.
Ls still has bottom end and rods u have to go aftermarket on SBC. Heads flow better then he makes it sound. Both are great engines but if u wanna make reliable long term power LS will beat sbc no matter how u bet against it.
@@mikehodgson9149i have a 500 hp 11.5:1 355 sbc in my 68 firebird street car thats been running a mix of 93 octane and vp q16 since it was first built in 2005 and it still kicks ass not many haven't been taken to town by an LS yet unless it was under boost or a had a bottle
😂😂 I’m probably younger than you are bud and I can tune a conventional motor. Ls is just the new sbc. I’ll always love the old sbc but technology wins every time
I think there is truth to your statement. Most people don’t have a clue what’s going on, period. And I am not a fan of those people bandwagoning and acting like know it alls/better etc
But EFI for a street car is just better. Better power in all driving conditions combined. Better fuel efficiency. Better drivability. MAYBE there are some applications where a carb shows more power than Efi, but it’s not quite that simple to have a real comparison. VS efi that can run closed and open loop to adjust for whatever random situation you’re in…
Add in the natural racing tune ability of EFI… so that timing changes dynamically during a run, or can allow for different AFR’s in different conditions, or even just safety (knocking, overheating etc). It’s just more reliable.
The thing that really sets it apart is how good the valvetrain is. Not just head flow, which honestly is only ok. Once you get into aftermarket heads, head flow isn’t hard to find on any good v8 platform. But, the LS has incredible valvetrain stability, with simple and minimal mods. Which means aftermarket heads also can have killer valvetrain stability for really cheap.
Not many engines can spin to 8-9k make over 2000hp with stock rockers, just a valve spring/retainer kit, decent pushrods, and a bushing kit. Easily spin 7-8k on factory heads with just rocker bushings, pushrods, cam, springs/retainers. Throw in a cheap $300-400 rocker arm shaft kit and you can spin it up as high as you want-bar maybe a little lifter tweaking. Aftermarket heads same deal or less.
And you can get factory valves that are stronger + lighter than aftermarket versions, that will fit in aftermarket heads, new in the box from GM, significantly cheaper than from the aftermarket.
The gen V stuff is even more impressive. And as time goes on, the gen v sbc will be the king. Sleeves are stronger in the alu blocks, direct injection allows more power on pump gas. Heads flow killer, valvetrain needs even less mods.
It’s crazy to me seeing Chevy fans act like Chevy didn’t design newer and better. The sbc, pg, th400… all are old designs. They’re great still today, but Chevy took what they knew/learned from those and made them all better.
I had a 383 long block assembled for my ‘76 corvette roller cam, roller rockers, Pete Jackson gear drive, 10.1:1 crank wiper, windage tray, baffled oil pan, , Air gap intake, Sniper EFI, Full Hyperspark ignition system, and a few more goodies. I am looking forward to some LS confrontations.
Careful what you wish for 😄
I have bought two 5.3 LS engines in "good condition". Most of everything on them is tired and old. Damn near everything has to be replaced. You are left with a block and heads. Everything else is junk if you want any level of dependability. It adds up $$$$ fast. Unless you're chasing 450+ HP or a race engine, the SBC is the way to go. Also if you buy a Gen 4, you automatically have to buy a $500 DOD delete kit.
I grew up building gen 1 small blocks and they are great engines. The future definitely belongs to the LS engine like em or not. I'm a BBC guy myself..if you're going to worry about cost of swapping or building engines you need another hobby.
Exactly, 4-500 hp doesn’t come cheap, making that level of hp with any engine is expensive, this SBC vs LS argument is stupid…

I just built a small block S10 on a shoe string budget... Got the truck for doing some work on a 53 Buick so no money in the truck itself... Ended up with a 305 small block out of a 24 foot Bayliner so it's a factory 230 HP engine... turbo 200 metric 3 speed auto for free since it sat on a barn floor for 25 years... Quadrajet came out of my buddy's scrap dumpster... So for gaskets, mounts, HEI distributor... Facebook marketplace shopping for the headers and Hurst shifter setup as bare bones missing covers and knob, shift cable and yoke to extend the driveshaft another inch and u-joints I and exhaust made from parts store bends and Amazon cheap flowmasters.... All in I was at just over $1500 bucks.... If I did an LS swap I would have had that just in parts and a msd controller without any other stuff... And now that it's setup for a classic small block... If I want to go up to a 327 or a 350 or even a 400... It's as easy as unbolt and bolt back in.... Gotta love a classic small block! Good video man!

@@hankclingingsmith8707 I will do it on my next build then......I wanted to keep it simple on my first engine.
305 is better if your running the 4.3 running gear. Makes less torque down low so you don't break everything. Granted a 350 is better. But I'd run some shitter traction tires so you'll burn them off the break everything else. Just watch your rpms and don't let it grab traction/ shock load until you have supporting mods for the rear to help minimize your load so you don't completely just shredd the rear end every time. Or drop you in a 2500-3500 rear end and let it eat. Just my 2€.

IF I were going to do a SBC it would be a well built 383 with good flowing cylinder heads and a not so lopey cam, headers, big single exhaust, on and on - and I would probably run someone's FI system and a good electronic ignition.
But you can purchase a good used and running 6.2 from an Escalade or Tahoe for about $3K - that makes 425 or so HP out of the gate - and use a factory or aftermarket ECM - headers, large single exhaust....and you will have a very nice and drivable package that is very reliable.
I don't see computer controlled drivetrains going away any time soon. The reliability, ease of use, the lack of regular maintenance or "tuning", and fuel mileage are all desirable features in my opinion compared to an old school SBC.
These two engines have their place - but if I had the choice I would choose a FI LS every time.
My opinions only.
Going through an L31 for my 71 chevelle right now. Intake, LS 6 springs, comp retainers, offset keepers, summit cam, a little bit of porting and keeping my old quadrajet. Should have it going by end of week... way cheaper then LS which would take a month or more...
I like em all, grew up on Gen 1-2 SBC and now messing a little with the LS Gen 3-4 engines. But I have to say junk yard LS swap is cheaper. We just swapped a 3rd Gen Camaro. We got a 5.3 for $600 with harness, ECM, accessories and all. We reworked the harness so the stock 5.3 ECM could get 12 volt power from the battery and a switched ignition source (old HEI wire). $50 ICT SBC to LS swap motor mount brackets. We did cam and springs for $600 and mail order tune for $300. We used the stock intake (which flows really good), fuel rails, injectors, and even the stock truck exhaust manifolds, etc... Runs low 12s in the 1/4. Car already had a TH350 in it so that made things easier. Good thing about it, if it ever blows up, go get another $300-500 5.3 and just swap it out. Them LS motors already have heads on them that flow like a SBC aftermarket head, I do not think you are aware of how well those stock LS heads flow. So basically we did this swap, with a cam, for less than the price of your heads.
You can see here the stock 799 head almost matches AFR head in flow and this is a stock casting head, and even the lowest flowing stock LS head does not fall that short.
AFR 195 Enforcer head flow
.200 = 133/104
.300 = 188/138
.400 = 226/158
.500 = 250/186
.600 = 251/197
706 LS Head Flow (one of the lower flowing LS heads)
.200 = 126/89
.300 = 180/126
.400 = 213/158
.500 = 220/180
.600 = 231/193
799 LS Head Flow (one of the better flowing LS heads)
.200 = 142/98
.300 = 193/133
.400 = 230/160
.500 = 243/175
.600 = 248/185
I like them both, I have a 4.8 in a jeep and pops has a 65 Malibu ss 327,I do all the engine work, love them both
I was contemplating going LS because the internet was making seem so cheap easy to. After doing some research on everything I’ll need to make it reliable and have the power I want I’ll be just about double the price as a crate sbc stroker.
I went that route 496hp 510tq
A lot of people who push an LS swap forget to mention the cost of mounting, exhaust, ignition and induction.... They are a great platform, but they aren't always the most cost effective for a swap
The reason everyone used to swap in sbc is the same reason people put in ls engines! They put them in everything and had good cross platform unlike Ford constant changing. I just went through my son's sbc and overall costs would have been cheaper to buy a 6.0l ls and spend a couple grand putting it in the 3rd gen. Why cause the ls is the new 350 and has newer tech and able to take high lift cams and out the box the lower end can take much more abuse oh and most important standard 350s aren't everywhere like when I was a kid. When I was 15 I got a running 350 for 100$ to put in my firechicken.
I got a 78 Z28 with a 355 ci, Brodix Heads & high rise intake, Lunati cam 640 lift, 264/270 duration @ .050, full roller, solid lift, 950 Holley HP, Bilitt crank, Bilitt rods, Manley. 030 over flat tops, Moroso oil pump. Naturally Asperated. IT SCREEMS!!!!!! No LS for me😅😅😅
Ive been on the same page as u and preaching to people that go on and on and on about the ls and it is a great engine but the small block is the best bang for the $buck$ hands down.
I love both engines. Ive really liked how easy it is to make 400 wheel with a car
Yup, agree 100%, I've been road course tracking a 93 Camaro for decades, as the newer stuff was getting faster, and I was having trouble running with them, couldn't quite keep up with the big dogs anymore, the boys kept saying you gotta put an LS in it, so I built a long, long stroke gen 2 LT1, 13.5/1 compression, Crower crank and rods, AFR heads with a little extra work on them, my own special grind cam Comp did for me, produced 640 lb/ft of torque on the engine dyno with a carb, in the car I still use the stock LT4 fuel injection intake, all on 93 Sunoco, I am now whippin the piss out of every one of them, one of the fastest cars on the track, this thing is an absolute track monster, built the engine in my street car to the same specs.

Bored and stroked the lt1 in my '70 camaro. LS swaps look even worse in my mirrors.
Not even a Chevy fan but this was an excellent honest video. I hate when someone says they got an LS because they are so reliable, how many small block Chevys do you see broken down on the side of the road, thats nonsense.
Truest words spoken.
Nearly every single one at 250,000 miles. Ls however is a totally different story. I build Ls. Sbc and bbc. No comparison in a sbc and an Ls. I’m building a roller bbc 10.5:1 compression and it won’t keep up with my wife’s mild 6.2. Also this video uses the worst 4.8 head made in comparison. Afr vs stock ls3 head. Ls3 head wins big
You would think this was the View with all the misinformation. Those heads don’t flow anywhere close to a stock ls3 head at any lift 🤦♂️
Just my 2 cents ls engines are way to hyped up. Yes tge did fix some problems that the first gen had and are stronger but they have there own problems. Never seen carbon built up in a first gen intake but every ls you take apart the intake is full of carbon and oil.
❤I've been saying this for ever. This was the best break down ever. I'd get paid subscription from you. My buddy just bought a Nova with a Blueprint 383 and Sniper and it's fast fast. Few of the guys have built 6.0 ls with allegedly 600+ hp and they are all saying something is l isn't right. The 383 feel way faster.
Awesome video. I wish I saw it before my ls swap. I was going to redo the original motor but it was only a 305. I probably should’ve taken the money got a 350 punched out to a 383 n had been better off but wats done is done. I will do that on my next project tho.
Definitely good info. I have a built sbc400 in my Foxbody but just went out and bought a 5.3 I wanna turbo 😬
Throw some 9:1 pistons in it and add boost. I did and made 1000whp reliably all year went 5.80s like a bracket car in a full weight belair and put MANY turbo ls 6.0s and 5.3s in there place
Loved this video man! You're funny as hell and informative
Misinformation. Ls not for everyone but if you want to hear from someone that is sober and knows engines look up Richard holdner. He is not biased and has a Dyno run to back up every engine combo he messes with
I have built both, in fact my newest build is a 5 3 in a S10 with a small cam(ss2). Honestly, I prefer the SBC. No hate on the LS, but it is overhyped with much of the info being regurgitated from what they heard, from LS fan bois. No, your cathederal port 5.3 is not going to build 550HP with just a cam. In fact, most will struggle to make 450 HP(there are exceptions). Sure, add a couple of cheap Wuhan war whistles, and you can build a monster, but the same can be said for the SBC. For a cruiser or driver the LS is pretty awsome, makes decent horsepower and will return good mileage, also start at a flick of the key, but if i want NA performance, i will build a SBC over an LS any day of the week.
Just want to add. 600+ capable off the shelf heads are available for under $3000 for a 23° SBC. Look to spend more then $5000 for 600+ hp capable rectangular port LS heads and chances are you will be waiting a while. A built shortblock to support either will both be equally expensive. Bit become original and build a traditional old school engine, the LS is pretty much played out. Again, no hate o the LS, it's a great platform.
I agree, I always get frustrated with "LS or bust" guys, even had one try to tell me a 6.0 was better than a big block to build to high power.... An LS is great, particularly for a boosted application, but as far as N/A hp dollar for dollar, it doesn't out class the sbc enough to justify the added cost of a swap. Small blocks keep things cheap, simple and fun. Honestly if I were to build a modern n/a motor, I'd do a Gen 3 Hemi with stock Apache heads that flow just as well as ported T.S.P gen V LT4 heads on intake and more on exhaust....
@@t.n.tgarageandperformance well if that's the case why don't they make more power than an LS max effort vs max effort
@7000U9ZHIFT Max effort vs max effort both engines would be in the ballpark of each other given both would have the best heads you could get along with all the high end components to go along with it. There's no inherent advantage to either platform if you throw the parts catalog at them. Besides, if you're going max effort, a Ford, a mopar or anything else you can squeeze a lot of displacement out of can make huge numbers and be almost indistinguishable for one another....
The rant at 0:40 seconds got you a follower sir😂
Listen man you just confirmed everything I argue with my buddies about on a daily basis, I respect the LS world but I will never turn my back on a sbc!! Power to the dollar and reliability you can’t beat em!!! And guess what?? I’m a foxbody 5.0 fan but I’m serious thinking about putting a 350 4 bolt main from like a 98 vortec motor in my Fox 😂
Priority cam oiling as opposed to main oiling in the LS platforms coupled with oiling pooling due to poor drainback in the heads scares me on LS motors. And I own an LS3. Seemingly the SBCs and BBCs never suffered from starving in sweeping left hand corners or oil cavitation, while the LS suffers from both. Due to the drainback issues and a vane rotor oil pump. Either platform will perform flawlessly with a dry sump but that's 6000$ or more either way.
Preach. No telling how many of my friends said ls he 57. I’m not made that way. Now my delima. Sbc vs bbc
You just got a new sub bud. May the sbc reign forever.
As God intended
Afr enforcer heads flow 251cfm @.600 lift stock ls3 823 castings flow 296cfm @.600 stock yeah the intake cc runner is bigger but at the end of the day the head is still recommended for a 4” bore point being I can find right now on eBay or Facebook marketplace ls3 heads for $500-650 a set! Because everyone is selling those to buy more expensive Frankenstein heads or Mast heads when the stock heads are amazing as is. You speak of cam swaps and springs. BTR makes a truck Norris NSR (no springs required) that makes 430 hp on a stock headed stock intake 5.3 truck motor. Yeah ignition boxes are expensive but not if you look around I picked up a msd 6014 for $250 and can use the stock harness to plug and play. Hell most people use the stock ecm anyway that you pull with the motor. You say $200 manifold for sbc, I bought a single plane mid rise for my ls for $140 and it would wipe the floor with any sbc $200 intake and would be on par with air gaps because ALL Ls intakes are air gaps since you must block off the valley cover. $300 for engine mounts and trans mounts? You can get ls motor mounts for $50 and if you use a th350 or th400 you can use a 6.0 ls flexplate to mount the motor to the torque converter drive and go. I’m not saying this to bust your balls it’s just I’m building a 355 and have sunk so much money into it to make what a 5.3 or 6.0 would make effortlessly. Those afr heads won’t flow anything without their $400+ intakes like the 4812 or single plane variants. That cam you put in that sbc it better be a flat tappet because if you’re talking roller and trying to make any power then you’re going to be at $600 or more out on lifters, the cam, and now new springs unless you have a newer factory roller block which then still you probably want to get new parts if you care about your motor at all. All ls motors have roller cams and pretty nice lifters and if those lifters aren’t good enough ls7 lifters are cheap and plentiful $270 on Amazon and eBay.
I'm Old School, not a big fan of the LS motors or swapping to the LS. Enjoyed the Vid. John
Love the video and agree with you but depends on what junkyard engine your getting, an 05-06 5.3 H.O. L33 has 330hp stock aluminum block and comes with 799 heads which are the same as ls6 243 heads you can watch a TH-cam video on how to port them, install a no springs required BTR camshaft build your own engine mount plates for like 20 bucks and butcher a wire harness together and have a 450hp + ls swap for less than 1500 bucks
Been building small blocks and big blocks my whole life. Drag cars and everything in between. Let me say this, tuning a carb is so easy compared to tuning LS swap. Anyone can tune and work on an old engine but good luck learning HP tuners and dialing that in. If your old and not computer literate stick to the old stuff. power is just a product of how much $$$ you spend. Thanks for the video!
SO I HAVE A 1995 C1500 CHEVY WITH THE SBC 350 AND NON VORTEC SO TBI AND MY FRIENDS BEEN TRYING TO GET ME TO SWAP IT BUT, ! IS EXPENSIVE, 2 I LOVE MY 350 RUNS LIKE A DREAMS AND ITS GOT SOME TORQUE, SHOULD I JUST KEEP MY 350 ?
@Pendragon69608 It really depends on your goals. If you don't care about making gobs of power, you can achieve 250 to maybe 300hp if you swap the cam, intake and run a carb... There's not a whole lot of potential in swirl port L05 heads.
If you want something that's fun to drive with 350-400hp, throw some parts at it. (Vortec heads or a budget aluminum set, along with cam, etc.)
If you're planning on making piles of horsepower (500+hp) Either pull the 350 and swap a 5.3/6.0 or big block swap it.
Both great motors. You've got to love the LS series top end. I'm currently putting a GM crate SP383 EFI into a 72 Blazer just because we don't want to deal with all of the conversion parts.
In a vehicle that never had a small bock, stock for stock, the LS will make more power for only marginally more money. Assuming you get your parts from a junkyard, you’re 600 for engine and trans on either one. Both options require the same components to run. This guys added cost of the intake and carb for an ls and the coil controller is irrelevant, because there is no real reason to run a carb on a modern fuel injected engine. Either option you have to either buy mounts or fabricate your own. The additional cost from the LS comes from buying a computer that has had security deleted, or buying a device to do it yourself (which costs $80). Is the sbc simpler to swap? Yes. Is it a better choice? No. I have no hate for the sbc, but I do get tired of people who preach how much greater the sbc is over the LS. Those people talk about how these people only do it because they don’t know how to work in carbureted engines, when they only do sbc swaps because they don’t know how to work on these modern computerized engines. Neither option is better than the other. It all depends on application
I swapped a LM7 into my 94 s10. It's my daily driver. I started with a good running and driving silverado for a donor. Body and frame were shot. Used as much as I could from my donor in my swap. It didn't cost me a whole lot for the swap because I already had my donor vehicle. LS swaps only get expensive if you go all out. A stock motor swap is not that bad.
Green question but I need help. I have a LC9 which is a 2007 5.3 L I’m gonna put a sloppy mechanic stage two camshaft in as well as LS7 lifters and 1218 springs in 799 ported heads. I’m kind of leaning towards using stock ls1 pushrods but if I was to upgrade them, what would you recommend?
Also, I’m considering on changing the pistons would you recommend changing piston rods as well? If so, do you recommend any of that are as strong or lighter my goal is 500 crank N/A.
@Speakertweaker-tp4em Stock rods are quite good, I would personally put A.R.P. bolts in the big end (machine shop can do that and resize them)
As far as pushrods, I don't think there's much to be gained strength wise unless you plan on running it hard up to 7000+. If your springs are really stiff, the stockers can flex... I like trick flow pushrods for any hardened sets, but any of the upper end mfgs have pretty good products
@@t.n.tgarageandperformance awesome thank you for the reply. If you don’t mind, I have a few more questions are stock LS1 rocker arms OK for my application. The engine is going into a 2002 Trans Am six speed manual. Also, would you change the Pistons or is stock OK? What? If I should upgrade piston what would you recommend? Also planning 6500 rpm max
@Speakertweaker-tp4em Factory rocker arms will work well, I've seen many factory ones live happily at 7k rpm, just make sure the trunnions aren't sloppy from excessive wear. Stock pistons will get you around 9.1 compression with 799 heads, so if you want higher compression, go with a flat top piston. Depends on your budget as far as what's best, Speed Pro, Wiesco are both good budget pistons, SRP are great for much more money. Same goes with budget on type of piston, Cast/Hyper are fine if you don't boost it or spray anything over 100hp (given good fuel and proper timing, personally I wouldn't spray on hypers) Good forged if you want to do all of the each, Wiesco actually has a pretty affordable option for forged pistons in their Tru-Street line. Now, if you don't care about upping compression, run the stock pistons, they'll hold up to a hell of a lot
@@t.n.tgarageandperformance my goal is N/A and 500 cran so I want higher compression for that so thank you for the flat top piston recommendations
@@Speakertweaker-tp4em No problem
P.S. love the pioneer stereo in the background there. 80's all the way. 🤘
why would you want a motor where a faulty sensor can leave you on the side of the road ?
Love it! I paid more than I should have for a 327 never ran it just took it to my local shop and I’m going to put it in a 78 nova that originally had a 6cyl. I’ll be less than 7k buying car and building motor I’ll obviously have more as go but that will be driving on the road price
Will this 400 horse engine survive in a BMW E36 drift car for more than 10 events If you're not trying to compete just fun days? Trying to decide between small block Chevy swapping or just turboing my iron block M50 in line 6
I've got a stock bottom end with the exception of ARP bolts in the rods. I would run an ignition box that gives me a rev limiter if I used it for drifting, but I would trust it.
It's really 6 of one, half dozen the other, the M50 is still plenty capable and you wouldn't have to swap everything.
Yeah when you make the math on your side ya can make it sound great. 600$ 6.0, 150$ for a inline pump and a rubber line, 30$ mounts and chop down your own stock harness. Throw a sloppy stage 2 and pac 1218 springs you will make just as mush power with a stock block stock heads stock intake stock injectors. Oh and I’ll daily drive it through the winter sub zero temps with no issues
I'm all about a budget swap, but guys that can do that kind of swap are more the exception than the rule. That's why sticking with the sbc is better for most people
My 2000 Z28 with a LS2 just made 480 rwhp with 799 heads. Not many small blocks can claim that under 400ci
I be fair q jets are slept on big time and can flow and make power. Best of all they run a d start easy on side hills etc.
I wouldn't even consider myself a beginner mechanic more of like a parts changer. Lubetech so I would much rather stick with the old school motor in my 84 k20 then to try to do an LS swap and run into a million problems. I have no idea how to fix old school motors doesn't have computers which I hate. If I was 10 times better mechanic I would consider an LS swap but it seems really complicated
I feel you.. I'm putting a 327 in an 08 Colorado just because I had a rebuilt engine and it came with a 4L60e
There's a reason you can find so many "half" finished LS swaps in your choice of platform on marketplace....people think they're dummy easy and that they can do it too....only some can.
The dollar for dollar comparison is not an exact comparison. Prices vary so much for used stuff and depending on how savvy a person is one may spend apt less to get something done. If starting from nothing I’d go LS and a mild cam in 6.0 and make 450ish. If you are swapping from a SBC of course is not gunna payoff depending on what you want. But for overall drivability an LS will make more power and be more streetable at higher power dollar for dollar.
The ONLY problem I have with a traditional SBC OVER the LS is the fact youre not coming CLOSE to the performance capabilities of a STOCK iron block 4.8/5.3/6.0 without a Dart Little M or such aftermarket aluminum block to make a MASSIVE cubic in. Stroker small block and thats not CHEAP! There's not a SINGLE Stock bottom end 2 bolt main 400, 4 bolt main or otherwise SBC that's EVER reached 1400 HP......the iron block Vortecs have.......not having to spend 2500 dollars on a stroker kit or forged rotating assembly is a GOD SEND for building an engine. Camshaft and Turbo kit and you can reach any sub 1400 HP level you want with a 6.0....YES it will make passes. YES everything breaks all racecars do. YES your SBC can make 600 HP or 800 HP but with as few parts and as little money spent? Not gonna happen.....you can run a carb on an LS too..... it's called the SUCCESSOR for a REASON! the fact it has 6 bolt mains is already the main reason it sticks out above the rest of the competition.
@ConcussedGaming I absolutely agree that the LS architecture is far and away better for high hp. The sbc is good for 400 hp without going 4-bolt or doweling the main caps, making a very viable option for better bang for the buck up to that point. 450-500 hp and above, the LS eclipses the sbc quickly in the most hp per dollar
I’m on the fence on what to put in my 80s c10 but what the LS has is fuel efficiency.
Yes and no, if you keep it fuel injected, sure. But if you carb it, there's no discernible change.
I can tune a carb to be just as good or better.
A well tuned carb and having a overdrive trans will get just as good mileage or better
@@joshuagarvey9362I hear that on the internet but I'm skeptical a carb is just as Good
If you look at 1000cc motorcycles back when they transitioned to fuel injection, they had the same fuel consumption with slightly less HP than the previous year (carbed) with the same engine. Tuned right a carb is just as efficient and you can tune it yourself when you do changes to the engine. FI is for convenience of not tuning for stock engines. You do get a little better off idle throttle response, easier warm up, less stalling on extreme grades...at the cost of complexity and resources to keep it going. I don't think fi is the way to go for hot rodding or performance applications. A carb just hits harder. Ride a fuel injected bike vs a carbed bike of the same model and then you will see.
I ls shaped a chevelle it has 500 hp I get 16 mpg cruising about 5 more mpg and 100 more hp that's why I did it to be honest it runs extremely reliable and puts down great hp.
I disagree with your crazy statement sir!!! I put a spreadbore Edelbrock on my 460 because I firmly believe the best way to make a Ford run right is to put some Chevy parts on it!!! I'm also using an HEI style distributor just because......
He is speaking the truth...but he sounds like...one to many beers...
@stevemitchell9848 You're not wrong, it was a long day in the garage
LS only makes total sense if youre on a tight budget and want the best engine for the least amount of money. However most of them i see are crazy aftermarket block builds with stroker cranks. People have been building sbc's like that for decades and making north of 1500hp so if you have to spend 3 grand on an lsx block you could buy a Dart block sbc for less and start there. Point being if youre spending 10 grand on aftermarket parts the platform doesnt matter anyway just choose what fits best in the car.
So you're saying that the square body that i spent 30 grand on with a SBC 350 with aluminum heads and Edelbrock intake and long headers that is sluggish off the line would make more sense to keep than LS swapping it? 😢
I went behind my wife's back and bought a junkyard L33 for $900 because I was disappointed when I discovered how sluggish this thing is and now I have to build it up. My wife isn't gonna be happy with me. Kind of wishing that I didn't buy that LS and should have spent money to beef up this 350
Depends on why the 350 is sluggish, could be rear gear is too high, poor tuning or internals that don't let the top end perform to its potential. Building either is going to cost $$, but you're money ahead with the 350 to build off of
@justingonzalez702 Sounds like you didn't know what you were doing building the 350 so I doubt the LS will turn out any better.
I like both platforms but economical the 5.3 is superior in price per HP. Blocks and rotating assembly are weaker in the SBC.
Im an old timer. Small blocks were all I ever had. Price and convenience of a sbc is so hard to beat. I wouldn't know where to begin to stick an LS in a project car. Never had one to take apart. Knkw nothi g abiut necessary harnesses and control units. All costly I'm assuming.
@rogerdonoho4924 LS swap components can get costly.... As far as mechanically, they're simple enough and very strong. But, a sbc will always be the most cost effective up to 400 hp I believe
808 350 block rings scat stock crank . A take out zz4 cam picked up vortec 906 heads with a air gap intake on cl 600 bucks .reused my old 750 holley. And oh ya bee hive springs comp + .050 locks and retainers same headers as before. 350 to 400 hp easy under 2 grand . I dig it .!! . 13.20 on motor 69 firebird 12.20 with a 125 shot . 4.10 gear 2500 stall th400 .
Ls = Oil problems !!!!!, Gen 1 SBC = no problems..... LS = has 4 big bolts per Cyl on heads, SBC = 5 big bolts per Cyl..... no problems !!!!! ... Generation 1 small block Chevy engines are more reliable and give you the best bang for buck and not to mention they do make power reliably if you know how to do it. 💪😎 💯% 🇺🇸
Ls = 6 bolts for the main bearings which is arguably more important vs 4 at best and the block doesn't come down as far leaving your bottom end weaker stock.
@@xninja83x67 2 small bolts of the 6 that do nothing... how do we fix the oiling problems and the fact that they kick head gaskets with too much boost
@jesseeaston1687 I wouldn't say they do nothing but id argue the way the block comes down farther the meet the main caps is the more important part, sbc just isn't nearly as strong in that area especially the 2 bolt mains. As far as the head gaskets going under boost Idk, never ran boost unfortunately (too much money and never end up pulling the trigger) I always build NA.
Are you talking about gen 4 + DOD lifter issues as far as the oiling problems go or are you talking about something else? If gen 4 then idk, I really am not a fan and prefer gen 3.
Well you tipped the scale, ive been going back n forth what to do, i have a tierd 1976 block 350 in my 92 c1500 hotrod truck that froze n popped a block plug...is it cracked? But it is on a tierd tapered .030 bore but i have a good 88 4 bolt main roller with a tierd stock bore in my cellar from my old truck. I found some .030 sealed power .125 dome hyper pistons for $211 (the dome is because have heavily worked over 76cc heads, those pistons have a 9.35:1 with 76cc so would still keep me above 9:1 with the valve de-shrouding) anyway redline said $260 for bore and finish hone, crank and rods seem fine prob take crank to work and polish it on the lathe with dynabrade pipe polisher and toss arp bolts in the rods with the usual diy mods or reuse my old rods that already have arp bolts so for around a grand i should beable to have a better than stock fresh bore 355 or find a 5.3/6.0 and swap it in... I would have to do buy schoenfield obs LS swap headers that are $400ish and upgrade my fuel system and deal with the ecu headaches or do the whole carb swap deal, i can say the Qjet on a 5.3 thing isnt nuts it sounds awsome! They are my favorite carb only carb i like better is the holley 4165 The 4165 650cfm mech secondary double pumper Qjet replacement is the goat street 350 carb imo. I had The 4175 vac secondary version also it sucked donkey dicks. I had aodified 800 qjet for years but it really did not like the duration and overlap of my cam and the original torker just aggravated it, it made great power but ran horribly rich all the time and about 8 mpg i tossed a cheapo used 600 edlebrock on and it ran beautifully great drivability still had lumpy idle but didnt burn my eyes and mpg went to around 14ish but a noticable loss in top end sack, but twice the fuel economy said lets roll with this for awhile. But short story long im just keepin it old school. I also have a nice 95 mustang gt (last year of the great 5.0) i want to make less slow so fresh 5.0 shortblock and AFR 185 enforcers howards cam and any good intake i can find thats not $1000 so i can get Maybe 350-375 hp hopefully...so every dollar i save is another dollar i can spend on that engine build and being a regular ol blue collar working jerkoff every last dollar is needed.
Oddly finding a sbc has been a pain in the ass in my area
Same here, many are starting to catch up and realize it's worth
@@oscarbear7498 sbc cost more then ls engines in my area
@@brettbaker8130 wow, that's ridiculous. American Civil War trending is probably why too partly, when the millions caravan refugees coming in from the souther border bring that massive future crime wave and AI keeps electing democrats even tho everyone hates Biden... one thing is for sure, you'll wish you had a sbc for whats to come
You just got another subscriber my friend. I go back and forth with the guys at work, money for money the 350 can beat an LS any day of the week.
Thanks for the sub!
You just can't beat the simplicity of the sbc ...and ease to work on with minimal tools ...especially if you get broke down on the side of road ...
Make a point. But driveable a issue also with chain slop using a dizzy hall affect sensor to run spark ...also old trans eat power unless go to stick...thought about alot of this ...those old blocks don't have lifter issues but a boosted engine always better ..ls or 350 or any engine
I was watching these guys with 500 more hp than I had back in the day run less than my 10.83 at 127 mph NA cars
Both were 455 on Pontiac one Buick
I have both enjoy both, ps that LS now from the junkyard is $900
I guess inflation really hit everywhere lol
Great video... subscribed from both of my channels! I just left the small block s10 comment!
LS vs SBC the reason u would use either is to gain modern design
SBC steel main caps , 4.125 bore ,, raised cam after market block
SBC chevy heads 400 cuin 220cc or 227cc AFR heads or 18deg heads with stock type exhaust mounting
LS--- whatever -----LS who
Owned every engine made..I just like it too look good..I found good in a lot of engines..
How much you got line them up
THANKS FOR THE VID. I RESPECT YOUR BREAKDOWN. GOOD ANALYSIS.
WHICH WOULD YOU RECOMMEND FOR A JEEP CJ ENGINE SWAP? (no insults please. Its all I can afford with all the baby boomers hoarding the muscle cars).
I HAVE AN ‘85 CJ7 AND WOULD LOVE TO PUT A V8 IN IT. LS SEEMS COOL BUT ITS HARD TO LOCATE ALL THE COMPUTERS IN THR SMALL JEEP. I FOUND A 350 OUT OF AN ‘86 C60. ITS COMPLETE WITH SM465 TRANNY. $750. LOW MILEAGE ENGINE.
YOUR OPINION? ANYONE.
Nothing wrong with any jeeps imo, I've built several myself. If you just want to get it running and have fun with it, I'd recommend the 350/sm465 combo. There's plenty of mount kits out there for old CJ's. You'll probably have to get driveshafts made no matter which way you go unless you have the jeep trans to bolt to the engine
@@t.n.tgarageandperformance THANKS! IS THAT ENGINE A GOOD CANDIDATE FOR A FUTURE 383 BUILD? OR IS IT BETTER TO BUY A 383 NEW ON A CRATE??
As long as the block is sound, you can build a decent 383. One thing to keep in mind is that the power limit on a 2-bolt main is 500 ish hp, the caps tend to walk in stock form at that point. I've seen plenty of 2 bolt 383's at 400-450 hp do just fine
@@t.n.tgarageandperformance Since its from a C60(?) heavy duty flat bed truck I’m hoping its a 4-bolt main.
Thanks again! I think I’m gonna try this 80’s sbc. I can’t even find an LS because all the mechanics are buying them and hoarding them (like toilet paper) from the junkyards.
@philippine_phin There's a good chance it could be a 4-bolt, a lot of gm trucks over 8600 gvw were equipped with them.
Ok, now lets be HONEST. What distributor are you using in the L31 sbc? Because it didnt come with one that will work with a carb. Are you going to use a 300,000 mile hei thats all worn out and so loose it doesnt hold time, and pushes oil past the bushings, or are you going to spend several hundred on a new MSD setup? O, right. Are you REALLY going to run a 300,000 mile quadrajet with worn throttle shafts that make it leak vacuum and impossible to tune, or are you going to run the same new holley you would put on a carbed LS? O, right. Do you really need to spend $400 on a LS carb intake, or can you buy a used one for $200 all day long? O, right. What happens if you spend a little more on a 6.0 instead of the 5.3? O, right. Who is doing your machine work on the sbc? You, with a dingle ball hone and a dewalt cordless? Is quality maching work on your " brand new " sbc free where you live? O, right. Do you really care if your bottom end is brand new in an LS when we all know most of them go several hundred thousand miles without fail? O, right. What happens if you buy a used msd for your LS? O, right. What happens to the price of those afr's if you want to spin a litte more rpm and make some more power in the future? O, right. It doubles. What happens if you are putting your sbc in a third gen camaro or a vette with low hood clearence and cooling issues with hot small blocks? Might be nice to have that fuel injected LS ...You make some valid points but you miss two for everyone you hit.
An L31 will easily run over 200k miles along with the 5.3/6.0
I used a new $100 dollar hei from summit, carb rebuild and bushings are $80. Had the crank checked, rods resized and arp bolts put in for $275. Bores were square, so I honed it. Aside from the carb being used, everything else was new. Now, you can pontificate all day about how to make an LS swap cheaper, but even if you average every price on used stuff, your argument doesn't hold water. Like I said quite a few times, getting a sbc to make 350-400 in a vehicle that already came equipped with one will be simpler and cheaper than swapping in an LS.... I've stated MANY times, the LS gives greater returns on hp per $ at 400+ and that the architecture is FAR superior to the sbc. My point is that the sbc is not dead for an easy build for guys who otherwise would be misguided into an LS swap when their hp goals aren't that high.
If I had a dollar for every L31 I've had to rebuild because it was run too long with a cracked head, I could do a dozen LS swaps. But, I'm not your average guy. They are a fine motor, but the early LS is better in every aspect. If you want to make the cut at 400 hp I kind of agree with you, but most people doing LS swaps are after much more than that, in my experience. Good luck with your $100 summit hei. I'd recommend carrying a spare ign control module in the glove box, and don't expect a vary accurate timing curve with it no matter what weights and springs you put in it. Been there done that. Never again.
And then you have to worry about a trans. 4l80 works from the factory, th350 aint cutting it. Plus all the swap cost for that
Im glad to hear someone else feels the same as me. Im sick of hearing LS this and LS that LOL. By all means they're great engines but so is a SBC. I just enjoy the simplicity of the SBC and it'll make plenty of horsepower for the street. Im sure this video made the LS fanboys go make sweet love to their LS's and wisper sweet nothings into its intake LMAO. If you cant make power out of an old school SBC you dont know what you're doing.
Most LS swaps are used engine swaps. For the price of a used LS engine swap you could have fresh rebuilt Gen 1 or 2 small block.
I like Ford and Chevy. And I don't go with a platform just because I'm that guy. I put the engine based on what's going to be best for the vehicle and what I want to do with it. I've got a 91 GMC Sonoma. Going to put a 5.7 Vortec LT1. Got it out of a 96 suburban. Good engine. Just a little bit down on compression on cylinder #1. Got it for $200. Going to do all the usual stuff. 30 over. Forged pistons and rods. Lunati bootlegger cam. Some nice heads. Air gap intake. Street strip carb. Simple. Cheap. Going to pound off like a muffukker. Plus. Cammed out small blocks sound cooler than an LS. But if I have a Corvette. LS is the obvious choice. If it's a Japanese mini truck and want to do a v8 swap. Obvious choice is a small block Ford. Because it's narrow. Distributor is in the front. Blah blah blah Ford stuff. Everyone would be better off if they forgot about all the brand loyalty BS. And just put whatever engine is the most logical choice for what they want to do. Weigh your options logically instead letting the brand/platform loyal bs make their decisions for them.
All valid points until you leave the carb world and go fi. Script flip GM didn’t offer a good FI option from the factory. TB is very difficult to tune, vortec fi is garbage, aftermarket fi is going to be in the thousands.
Just for all the LS’ers…#SRH Project 900 #23degreebadass
I prefer original small blocks.
Yeah burnouts and donuts are cool. If you have a tire sponsor. But they don’t prove that it’s fast.
Not to mention those low profile lowered vehicles spin tires cause the suspension is all wrong.
How about lt being a 6 bolt main and even used out the junk yard holding together up to 1500 hp
The issue you run into on alot of the engines is no one does the cam bearings they put a new cam in and redo everything else. It'll hold together for a bit but what ends up happening is it spins the bearing out on the cam. Cam breaks in the block and trashed the whole engine except a few misc things. Had a buddy build 3 of them 1000 HP turbo 5.3s blew threw a lot of money. Took him 3 engines to learn that you can't cut corners if you want it to last.
Yeah you don’t make the big numbers on LS engines without aftermarket heads and cam.
Yeah I love both but you went the most expensive route on the LS. You just get one out of a wreck harness tranny everything cam springs especially if you go for a 6.0 and you now have fuel injection more power and a strong bottom end. Most haters are just afraid of wiring to be honest.
I 100% agree with people not liking them because of wiring involved to run a fuel injected LS, I've seen many swap projects abandoned and sold, most likely because of that very reason. Is a sbc better than. An LS? Not in a million years... But for what most people are looking for performance wise, a small block is very capable for reasonable money and simplicity, given the vehicle had a small block available at any point.
i agree @@t.n.tgarageandperformance
if I were to have a carb again I would probably build an sbc over an ls to be honest
I have a daily driver 2010 camaro Lsa conversion LS3 makes 900whp daily with air and heat. Show me a sbc that will do at least the same! Or help me understand . Because I know no-one with a sbc with those power levels reliably.
With all due respect, you missed the point of the video. Sure, if you take a car that already has a LS platform engine, nobody in their right mind would swap it for a sbc. The point is, N/A for N/A in an older vehicle, (that was made with a sbc) it makes more sense to build a small block to 400-500 hp than justify the added cost of an LS swap. Of course, when boost comes into play is exactly where Gen III, IV and V motors shine.
As far as a 900whp sbc, it can be done reliably with a doweled 4 bolt and a quality rotating assembly. But no one would build that when the LS is there for those kind of power levels
@@t.n.tgarageandperformance either way cost is in direct proportion to expectation.
It would be interesting to see a 23 degree head 350 hang with a gen 3 lq9 with a set of 243/799 heads and decent stage 3 cam. Carb or f.i. Dollar for dollar.
I prefer the LS platform but wouldn’t bash sbc .
Smokey yunick built a 229ci sbc twin turbo for indy that made 1000hp and that was waaay back in the day
You’re making those numbers because of the supercharger and other components. Put a supercharger on a built sbc or big block, those engines may make even more power safely.
Why do ppl throw around dyno numbers like they mean everything. Dynos numbers can lie or be manipulated. If you really make 900whp. (Im not saying you not) you will run 9.60s or close to it in a 1/4 mile in that car. Personally took a afr headed 383 in a g body regal full interior. Made close to 600 on motor. Hit it with a 300 shot. Went 9.91 that was only about 900 at the crank. And yeah it was street driven. No its not going to be more efficient than a ls. But apples to apples cubic inche to cubic inche it can make the power. Dont forget you are comparing a 23 degree headed motor to a 15 degree. Imagine if you did a 18 or even a 15 degree headed sbc. Numbers would be crazy. (Since we playing a numbers game) Ps been apart of a team 4.51 in a 92 mustang with a procharged f1x afr 245 406 sbc 30 psi of boost. Lol made 1600 on a hub dyno with 26 psi of boost. Its a 4xx sbc 23 degree headed chevy 2 local in michigan. Car gotta be running 4.20s 4.30s. Point is sbc can make power and do anything a ls can except get mpgs (gas mileage) lol
I detect a whole lotta jealousy here! You know as well as everyone that a LS will slap a hairlip on a gen 1!!! 😂😂😂
Quadrajet on everything!
Lol
We have a 88 Silverado that came with a tbi 350 i swapped it out with a smaller 4.8 with a mild cam. Picked up almost 2 seconds in 1/8 mile. I think this guy is drunk.
You took out an engine that made maybe 210hp and replaced it with one that made 275hp (stock) then cammed it and gained 2 seconds... Wanna pull anything else out of the no shit pile? You also could've thrown a cam, vortec heads, intake and carb on the 350 and accomplished the same thing without needing to spend anything on motor swap components
@@t.n.tgarageandperformance not without spending a time on aftermarket fuel injection, or stepping back in time and carbureting it
@mkfarmer68 if someone is dead set on fuel injection, then yes. But, installing the 4.8 and tuning it also costs money, and that's my point. Dollar for dollar at the hp level, the LS has no real advantage cost wise. Of course, that 4.8 will eclipse the sbc in higher hp gains (400-450+) per dollar. But if a guy already has a sbc powered vehicle that wants 350-400hp for the best bang for the buck, it's easier to build the sbc. Not everyone wants to ls swap and sometimes get misguided into thinking that's to only way to make power
@@t.n.tgarageandperformance absolutely wanted to stay efi. I sold the original engine which cover most of the extra cost of LS swap. It’s also a 16 year old girls daily
@mkfarmer68 I totally get the staying injected then. I put the 350 in my son's 86 c10 with a Holley 670 and wanted to pull my hair out a few times getting him to learn how to run it
You're likely not gonna make 450hp with THAT 350 you described.
Btw....i just made 548whp with a 5.7 LS.
I agree, it's more 375+, 400-ish with good tuning and a better intake like an RPM air gap. 450 would be achievable with much more cam (which is roughly the same price as any other roller.) I don't doubt your engine made 550, my buddies old Camaro built in the mid 2000's made 496 who with a fast 90/90, old lingenfelter heads and a t-rex cam
@@t.n.tgarageandperformance funny he used old lingenfelter heads. I used old gmpp cnc 243s. I think lingenfelter did those heads for gmpp.
