Count me as an LS1 lover. My 2002 Camaro Z28 came from the factory with the LS6 intake, and always seemed to be able to run with cars having 50 more advertised HP in track days. On the chassis dyno at 60000 miles, it put down 305 to the wheels, which is what flywheel HP was rated at from the factory. Judging from the chassis dyno, I estimated it was making 350-360 at the flywheel. Magazine tests from back in the day showed that LS1 F-bodies were making wheel HP that was close to the factory advertised HP, so the 4th-Gen F-bodies were sleepers and great performance bargains. Eventually I upgraded power mildly with a cat-back exhaust, gutted cats, low-restriction airbox, and large MAF sensor. Those made a noticeable gain in power above 5000 rpm. I got a kick out of the cam swap into the stock LS1. The 212 cam picked up 40+ HP over stock, which was 196 intake effective duration. (The factory LS6 cam was 204.) Better yet, the 212 cam picked up torque everywhere. It would have been a great upgrade for me. I did 16 years of track days with it, accumulating ~200 track hours. I thought it would break at some point, then I would put an upgraded engine in. BUT. THE. L. S. 1. NEVER. BLEW. UP. The only problem I ever had with it was two broken exhaust studs and a leaking exhaust gasket on the drivers side. Now it's got 290k miles on it, and doesn't have any mechanical noises. Oil consumption is up to ~1qt per 1000 miles. But the chassis is showing the deterioration of a car that has 19 Michigan winters on it. So it's retired from track use, but performs fine for daily driver duty.
1qt per 1000 miles? Is it leaking or is it consuming it, thats alot. Have you checked the pcv ? If pcv is not blocked, I would take it apart and rebuild it. Seems like the p rings too worn out.
My 2001 HSV (Holden) Senator M6 with ETP215 heads and my specced Comp Cam - 215/223 @111LSA on XFI lobes with LS6 manifold is making 415rwhp and is awesomely tractable on the street. It's a grouse street combo for a heavy sedan.
Owned 7 3 -5th gens LS Camaros Been grudge racing since age 14, bought my 1st at age 18 till tody Ls1 base car my 346 aluminum motor , T56, 342 gear going through the hot rod motor stages from headers long tube 1/7 , slp loud mouth 3 inch Y pipe 255lb fuel pump 80lb injectors did 2 cam swaps 1st was a GM Hot Cam , 2nd I desided to go max effort I put vengeance vindicator biggest cam with no ptv issues with a tune rear Dyno HP was 510 HP cam only, then I kelpt upgrading to go faster in grudge racing coming from Sbc Gen 1, 2 people get what a older Sbc motor likes confused with what LS likes hince why I had to double dip with cam swaps all Gm Ls motors feed better on big cams I was the 1st to put a true stock tq arm suspension small tire car full weight into the 80s 5.80s in the 1/8 bk then now I'm rebuilding to go faster so that's normal for a cam only small ish cam Ls1 motor Ps my building grudge racing since age 14, do not build by parts with the mindset of how older GM Gen 1, 2 lt1s till late 1997 when GM release the LS platform engines these engines are far better from OEM design from factory deep skirted blocks, bigger cam cores in size to be able to run big duration lift cams with no problem to stock LS heads flows BBC to better block material, 6 bolt main cap design with 2 side cross drill bolts to stop the crank from walking unheard of from any OEM factory design motor just like bk then people telling me a 4k stall converter was to loose and will blow through all lies . Keep inmind only GM Ls and new Lt motors from factory can handle over 1000 HP on stock GM fasterns crank was something you had to buy a aftermarket Dart type block to do so. With that in mind understand LS loves maxed out parts applications less focus on well I gotta by a drop in after market crank , GM OEM crank will handle a ton that will save you $ for other things you want to do. They are reliable even on stock oem replacement crank bearings, water pump OEM stock fasterns so much more you don't have to waste extra $ on will help you get to your goal faster. But again for a small to cam like you got those HP numbers are rt dealing with non max effort parts. I've sprayed 300 even when progressive nos system wasn't big and could not hurt my sbe motor, a drop pistons rods an ARP studs kit if you want to stay stock cubic inch will give you peace of mind over 1100 HP on stock rockers so much more couldn't be done until LS came out. Tune, gas, plugs will carry you a long way. One time we disassemble LS motor only to gap pistons and reused everything else lietterly all true statements I'm telling you.
Respectfully Ls3 swap is the typical thing people say when they are just too lazy to build the ls1,6,2. Only understandable reason to do it is if one lives in a carb law state like me in cali or ny.
Yes 👍 I've been waiting for the 5.7 Exclusive mods. I'm still working parts out in my head. I really need to know witch Cylinder heads will give me FULL POWER ,in conjunction with a Elgin sloppy stage 2 and fast intake .Thanks again , your a big help .🥳
Texasspeed 5.3 heads stage 3 are a good budget head to go with your budget cam and will give you a compression bump.450hp wheel with magic stick 3 camshaft
That old XR275 cam still works good, not a huge cam by any means. I put that same camshaft in an LQ4 with a TBSS intake, 92mm TB, and LT headers. It's stuffed in a GMT800 RCSB truck, runs really well and wants almost 6500 RPM at the peak. I believe it peaked at 6200, and wasn't down much more than 8-9 HP at 6500.
Appreciate you for doing this video Richard..the OG 5.7 ls1 is the equivalent to your junkyard 4.8 and 5.3 which we never got here as we simply didn’t get any trucks with LS motors in them ..we got ls1,2,3 only
I learned I need heads and a Fast intake. Running a 227/235 .618/.605 110 LSA cam with stock heads and an LS6 Intake. Richard making me spend money as usual. 😂
Cool look back at the LS1. You can build one today by boring an L33 to 5.7 bore, about 3.900+/-. The interesting point I got out of this test was the OG FAST intake with the RHS heads and the little cam did way better than the Edelbrock intake with the 459 cam in the (apparently) same long block. In fact, those looked really close to 6.0 numbers. Those RHS heads must be very well matched to the FAST intake of old. If I were building one now I’d use the Dorman LS2 or a TBSS, whichever I could find/afford, maybe TFS 215s, and a medium-ish cam. Thanks Richard!
It's ok we're running out of ls1s now it's cheaper to buy the truck motors an bring them over but I still personally thank you as after watching all your vids all my LS powered cars run high 220 duration cams as I don't like giving up powered down low
We keep wanting to run our nose down at "only the LS1", but then you see all this power being made. The proflow was down closer to 15ft-lb at under 5500 over the truck intake, some might not think it's a big deal... The 50HP on the upper end is more important.
Hey Richard how about a 5.7 mashup? Not just American made five Points something liter engines but Toyota and Nissan as well. You're quite the magician let's see what you can do brother.
I love these LS videos, they’re super entertaining. Could you do a video on the Nissan titan 5.6 dohc motors? They’re starting to pop up in junkyards more and more frequently and they’re a very very well built engine block.
The thing is about them there's almost 0 aftermarket support for them all you can realistically do on them is port the heads intake manifold and throw some boost at them and that's kind of boring to just look at the same power curve higher up in the chart
I'm doing a swap with a low mileage 02 LS1 from a Trans Am (came from factory with the LS6 intake), so I really like seeing Richard toss an LS1 up onto the dyno as I'm still thinking about what mods I will do after the car is running. I really don't need to go for a bunch of power as the car should end up around 2400-2500 lbs , but will do at least a cam at some point and likely heads too.
If you can find a set of 243 castings just throw them on stock with a cam in the low 220s 600 lift and you'll be happy. AFR makes a budget casting that replicates the 243s basically but are suppose to be an improvement so I assume they're decent. Some PRC heads might be a good value too. 243s should be worth 15 hp over an stock LS1 head on a cammed engine.
@@richardholdener1727 I'm talking about the enforcer not the cnc heads. Enforcer heads are $609 ea. They state that they are an improved 243 based head.
Richard I run a 246-252 cam with 108lsa on a SBE Ls1 with flycuts and decked and ported heads with a carby never dynoed, I’d love to see real cams and tighter lsa as a test on a SBE I know it needs way more revs to make power bit wanted that oldschool sound
My combo will be... sorta close. 5.3 bored to ls1 size, 3.26 crank, 12.9 compression, solid roller. Should make peak power in the mid-7k, cam and springs are set up for 8k+
@@tadwiltman4875 I had the same idea... So I started investigating Australian... LS1 builds... Knowing that they were into high raving engines for the burnout Box... And they have some high reving LS1 builds..
Awesome video as always. Can you recommend a cam for my 98 C5 auto? Going from perimeter bolt heads to ported 799's milled .020. From the LS1 intake to an LS6. Gotta keep the exhaust manifolds for emissions. Car already has 3.42 gears with a YANK SS3200. Daily driver/weekend warrior. I race it, but it needs to remain a nice driving car. Don't need all the chop. Dont want super high lift, or have to worry about P2V clearance. Just need more power without making it a pain to drive! Thanks.
@Richard Holdener Great video! Thanks for thinking of us Aussies! I was fascinated by your small cam testing. I have a 2004 5.7 with a TSP 216/220 .600/.600 112, heavily ported 241 heads and all the other usual bolt ons. However, I still run the LS6 manifold and TB as I was told I will probably make no gains with a Fast 92 with my small cam. Your results seem to indicate otherwise. Would you expect any improvement from moving to a Fast 92 and NW or Warr TB over the LS6? Or only worth it if you have an LS1 manifold? Thanks 👍
@@richardholdener1727 Thanks! I was expecting small gains and it's an expensive mod down here, so usually reserved for big power combos but interesting that there should at least be some gains.
@@richardholdener1727 I have a 01 C5 with BTR stage 3 cam kooks headers long tubes full exhaust. Would a stock 706 head make more power then the stock 241's??
Richard I got my hands on a LS1 from a 2004 GTO and transmission. And it only has 40,000 miles on it. I would like to install a cam, heads and intake. I liked what I saw on this video. I’m putting this in my 1997 SS Camaro. What cam, heads and intake would you recommend?
I’m swapping a 04 GTO LS1 into a old Yota only has a upgraded clutch/flywheel, injectors, Holley efi, cam, springs, pushrods. Trying to make an easy 500whp for now to enjoy still can’t seem to get an answer as to what else to do to make that. I thought of porting my own heads but seeing these videos just makes me so indecisive on making a choice. I want to be n/a for now too just so I don’t break the frame.
Richard. Thanks for the great content. I love watching your videos on cam and head comparisons for the LS1 engines. Would it be possible for you to do a dyno run on the com cams # LS3LX270 carb legal 210/218, against the stock LS1,LS6, and non-carb legal 212/218 cam. living in california is a struggle with upgrades and meeting compliance. Thank you.
@@richardholdener1727 yes, released in 2017 com cams FSL 210/218, 570/541 lift, 118 LSA. Carb # D-279-13 claimed to be 50 state legal. Would be interesting to see what the gains would be staying legal
How much would a FBO LS1 make with stock cam and heads? Longtubes, FAST 92 intake/TB, under-drive pulleys, cold air, and of course a decent tune. Want a set of ported 243s next. My car is a daily driver so I want to keep the stock cam. Haven’t been on a dyno yet. None here in my area.
Great video! I just picked up an LS1 with an LS6 intake that im going to swap into my old DD Volvo wagon. On a dyno sim program I have I plugged in the numbers to find the best average hp cam from 2000 - 7000rpm and it gives me like a 217/223, almost identical to the old "California love" WS6 cam.
I think you will be left wanting more are you planning on doing heads or just cam there are a lot of good cams Texas speed has a lot to choose from and they have never let me down
I'd go with something upper 220s low 230s .600 ish lift 113ish LSA. That cam you mentioned probably isn't going to rev to 7k. With what I mentioned your probably around what most companies are calling a stage 2-2.5 cam. Any decent place should be able to spec or recommend something specific to your needs
I have a 5.7 M6 with a TSP 216/220 cam and LS6 manifold/tb but also ported heads, peaks just under 7000 rpm (I shift at 7000 rpm). It's nice on the street. Was looking at a Fast 92 with NW 92 TB but tuner said don't bother. I am curious if it would add anything.
@@jamestoby2552 it would add power but you're looking at 1500 for the combo plus installation and tune assuming you don't do the install and I'd guess you would get 7-10hp with that small of a cam.
I'm playing with a tired 99' Camaro with a stock ls1 but I think the heads were milled cause compressions around 11 to 1 and 3.42s I just swapped the blown t-56 for one outta 05' GTO so its geared Lil lower now. The car was supposed to be just a doner parts car But It feels really good just banging gears in just a stock n/a Camaro, Not like something thats overpowered, unreliable and unpredictable Kinda like driving go-carts. able to get lil rowdy with my young boys who love Burnouts peeling out and getting sideways. Like being at Disneyland. So the $3000 shitbox has kind of turned into my summer project. I'm gonna race my Buddys 2012 LS7 Corvette he paid $40k hes also the old owner of my car, His ls7 he has now dyno'd around 640hp. with a Cali cam, MSD Atomic intake, and its tuned. I know even with the spare parts I already have laying around (comp Xer 281,Ls6 intake, maybe the Ebay long tubes , HpTuners and some fatty Nitto drag radials) . I still have little to no chance So I gotta dig around my garage and try piece together my old NOS setup. try to make a100 shot and get some decaps tested, On the bright side he's a shitty driver and lil afraid of his pretty lil garage queen. It only has 10k miles in 12 years. So most likely sporting the original factory dried out tires . I just want to earn those bragging rights before that overpriced monstrosity drops a valve! lol
I drive a 2000 Z28 I bought new. I'm looking to possibly upgrade the engine during a refresh in a year or so as it has over 180K on the odometer. My question is, what can I do to the engine and not have issues with emissions here in Arizona?
Im in the process of rebuilding my lm7 5.3 into a 5.7 have some leftover parts. I was thinking stock ls1 intake ls1 heads ls6 springs &ls6 cam curious on what the numbers might be any thought? Also a big fan have literally watched all your videos especially the lt1 series.
I haven't seen a combination like mine yet to know what hp i should expect, LS-1 stock heads, upgraded valve springs, sloopy stage 2 cam, 1 7/8 headers and a 102 fast manifold
As a iron head porter i look at the LS1 and see the Ultimate top end and they Barely get by on compression .But The Runners are to big to be turboed or supercharged . It was ment to be the Ultimate Naturally Asperated Race Engine . You dont want to shave heads . you want to shave block after stroking it 45 thousandths if valve clearance allowed At 13 to 1 compression it would perform like no other. Starting with 500 horse plus 650 lift bump stick better valve springs Bored to max upping the tork . it would even Devour the SB2.2 As a 355 reving high There would be monsters around here lol
Need opinions on what cam to run in my C5 LS1 5.7. Im mainly going with full bolt one, but I want a cam that will give me good power mid to high, chops good, and is suitable for street/daily use, I like to drift sometimes. Read that the 226/232 600 112LSA is a good choice can make great power not too big of a cam. The other is Texas speed 232/234 600 112LSA and last 233/239/600 112
Richard, can you make a video on that water pump? My group and I have been going back and forth on if it actually yields any power. I swear by them where as a buddy of mine claims the $500 isnt worth it.
the mechanical water pump requires power (PARASITIC LOSS) to produce the work (moving the water), DIFFERENT DESIGNS ARE MORE OR LESS EFFICIENT, an electric pump frees up some of that lost power
I’ve got a 5.7 GTO with 4.11 gears, building a try hard 1/8 mile car. Should i worry about torque? I’m hoping the gear set will make up for the lost torque if i go max power for the 1/8th. Not worried about drivability it’ll almost never see a stop light

Everything seemed very close to the 3 dynos. Ms 4 cam is big no fly cut tho . Good tuning not a very hard car to drive in traffic. Clutch gets a lil temperamental. But u wait for a gap an rip a small burnout. Problem solved lol. Hope this helps . Cats dislodged overtime and hurt number 7 low compression. Ls3 gapped is going in next.
What cam would you recommend for a LS1 with 185k miles? It’s a daily so I wouldn’t want anything crazy just something to give a bit more power and a mild chop.
So I'm about to build my 5.7 2002 ws6 automatic. I'm getting all new from crank to intake. I just don't know what to buy. I going weisco pistons k1 h beam rods. TX speed balanced crank. Lsx fast 102 mm intake. I just don't know what cam and heads to buy. I will be driving it 80 miles a day 5 days a week. I do want some "lope" but still want longevity. Any thoughts?
Also, I didn't see if you had done anything besides replace the pistons on the power rotating group. Did you replace this stock powder, metal rods or the crankshaft or are they stock?
@@richardholdener1727 damn! You can get 6700-7000 RPM from a cast iron. Crank? Jesus, Mary and Joseph! I guess those powdered metal rods or something, too! Last time I played with any of this stuff it was 40 years ago. Seems to me if you were going to build a modern day hot rod in a classic car. Chassis just go get one of those 5.7 or 6L ls1s. You start out with over 400 horsepower. Any kind of spreadsheet or matrix you can get on All the variance, passenger car and pickup models, s/n, etc? I hear guys are buying these at the junk yards for less than $1,000? Dang! Do you get the engine management system with it??
I’ve got an LS1 Corvette 5.7 in my 1996 MasterCraft 225 VRS ski/wake boat. It’s been sitting 10 years and I want to up the power/torque. I need it all to happen from 2500-4500(max). Is there a cam I should looking at for these parameters, or just leave it stock and freshen it up?
What does it matter, the shop wanted to charge me $4k just to put in a new cam with springs. I asked about a turbo build and it was $6800 which was probably the better deal since I would make much more then 50hp from a cam. Either way, my wallet would be drained.
This video reminds me of the days when magic stick camshaft 5.3 portedheads and 200 shot of nitrous was the secret combo to kill almost anything even boosted slowbras were getting taken down everyone always said why you running smaller heads your gonna be slow lmao 😂
@@cstavro @Chris Stavro Close. Try the new 3.86" factory crank from GM for 370 cid. Just got done looking at the combo. 10.0:1, LS2 cam, Trailblazer SS intake. Should be a good truck combo. Using the LS2 cam to pass smog here in California and it's plenty big for a truck. Cheers
I just had an ls1 built to a 383 stroker, 11.5:1 compression, 243 heads port/polished, holy Hi ram 102mm, long tubes, bigger cam (cant remember the specs i have to find my card) with a built 4L80. Its going in my 03’ rcsb silverado net month. Im very curious what the dyno is gonna say. Any guesses?

And should I upgrade to Walbro 460 as later add some psi
Hi everyone,I know this video is old. But I have the old G 5.7 with all the bolt ONS a small cam 227/235 565/579 110 lsa.ls6 intake,ls6 oil pump timing chain, ported tb with lt,I was wondering what's a good set of heads will go with my setup?
What value are we using for Stock LS1 cyllinder heads flow? I keep seeing ( 220CFM for unported LS1 heads ): Lit Intake Exhaust .100 66 51 .200 140 94 .300 193 126 .400 210 150 .500 219 162 .550 223 167. So when you put aftermarket heads in the combo we are assuming closer to 300CFM peak flow, usually past 280? At least 50 additional CFM? The camshaft on the stock engine showed 470HP/450ft-lb and with the aftermarket heads and aftermarket intake was able to do 550HP/490ft-lb a gain of 50-80HP over stock LS1 head.
Thanks, Richard. That's what i wanted. I'm just looking for somewhere to start. I have an og ls1 with lingenfelter gt12 cam and stage 1 cnc ported 799 heads. Cam is 227/235. 621/657. Have 6014 with dual plane intake and 750 hp holley.
Sweet. I got a 6.0 and recently a ls1. My ls1 seems to respond better down low with it's 862 heads than my 6.0 and ls3 heads. Both have 273 gears both are in 01 camaros but the ls1 car had a built 4l60 vs the 6.0 with a 4l80, same 3600 stall rating. My 6.0 gets stomped in the 1/8th and 30 roll, but on the hwy it's pretty even till about 80mph then it's no contest. Oh and the same 228 cam
4l80 might be part of the issue. Taller first gear, much heavier, and because it is so much beefier parasitic losses are higher. Biggest thing is probably the gearing though. Stock 4l80 gearing is not very friendly to cars without big hp numbers.
Definitely the transmission is the difference.80s first gear is tall and long eats a lot of power.60s are weaker but man they don’t rob any power and with any gear it will chirp the tires. Put 410 in the 60 and it will feel like you added 100ftlbs of torque
Yessss.. 5.7! Spec'd out mine recently. Wish list is ARP fasteners, FAST intake/TB, TEA ported 241s, & a comp 227/235 cam 🤤 go go Camaro!! You da man Richard!
So if you take two naturally aspirated engines of the same displacement, one stock making 200hp and a built engine making 400 hp, you take a turbocharger and put it on the 200hp engine with 15psi of boost to make 400hp, is the engine that’s boosted under more stress just because of the boost or are the two engines under the same amount of stress?
The boosted one I'm sure has more stress cause of the boost applied., been wrong before tho lol...Both will have stress applied at some level...at w.o.t honesty
The boosted engine is under more stress. Both engines NA are under 1 bar. For the 200hp motor, when you add 14.7 lb of boost to make 400hp. Now that engine is under 2bar. 1 atmospheric and 1 bar psi.
@@tomcelica What are you most worried about? Scuffing pistons? Valvetrain failures? Rod failures? Blown head gaskets? the NA 400 HP engine will be under more stress due to higher operating speed, and the boosted 400 HP engine will be under more stress due to higher operating pressure. Did I shed a lot of dark on the subject?
I’m sure it’s not making that kind of hp, I feel like I could run a ported msd and get way closer. Mods are ported fast 102, trick flow 215’s, solid roller 244-253, 109 Lsa, 680 lift. Fly cut pistons, Ewp, arh 1-7/8 headers.

Owned 7 3 -5th gens LS Camaros Been grudge racing since age 14, bought my 1st at age 18 till tody Ls1 base car my 346 aluminum motor , T56, 342 gear going through the hot rod motor stages from headers long tube 1/7 , slp loud mouth 3 inch Y pipe 255lb fuel pump 80lb injectors did 2 cam swaps 1st was a GM Hot Cam , 2nd I desided to go max effort I put vengeance vindicator biggest cam with no ptv issues with a tune rear Dyno HP was 510 HP cam only, then I kelpt upgrading to go faster in grudge racing coming from Sbc Gen 1, 2 people get what a older Sbc motor likes confused with what LS likes hince why I had to double dip with cam swaps all Gm Ls motors feed better on big cams I was the 1st to put a true stock tq arm suspension small tire car full weight into the 80s 5.80s in the 1/8 bk then now I'm rebuilding to go faster so that's normal for a cam only small ish cam Ls1 motor Ps my building grudge racing since age 14, do not build by parts with the mindset of how older GM Gen 1, 2 lt1s till late 1997 when GM release the LS platform engines these engines are far better from OEM design from factory deep skirted blocks, bigger cam cores in size to be able to run big duration lift cams with no problem to stock LS heads flows BBC to better block material, 6 bolt main cap design with 2 side cross drill bolts to stop the crank from walking unheard of from any OEM factory design motor just like bk then people telling me a 4k stall converter was to loose and will blow through all lies . Keep inmind only GM Ls and new Lt motors from factory can handle over 1000 HP on stock GM fasterns crank was something you had to buy a aftermarket Dart type block to do so. With that in mind understand LS loves maxed out parts applications less focus on well I gotta by a drop in after market crank , GM OEM crank will handle a ton that will save you $ for other things you want to do. They are reliable even on stock oem replacement crank bearings, water pump OEM stock fasterns so much more you don't have to waste extra $ on will help you get to your goal faster. But again for a small to cam like you got those HP numbers are rt dealing with non max effort parts. I've sprayed 300 even when progressive nos system wasn't big and could not hurt my sbe motor, a drop pistons rods an ARP studs kit if you want to stay stock cubic inch will give you peace of mind over 1100 HP on stock rockers so much more couldn't be done until LS came out. Tune, gas, plugs will carry you a long way. One time we disassemble LS motor only to gap pistons and reused everything else lietterly all true statements I'm telling you.
High reading dyno! That wouldn't crack 400 on a small cam like that.
Thank you for the LS1 content! I can't wait to install the 219/225 cam I bought off of you for the LS1 in my Nova
I found the best way to get more power out of my LS1, I swapped it out with an LS3….. problem solved instantly!!!
Respectfully Ls3 swap is the typical thing people say when they are just too lazy to build the ls1,6,2. Only understandable reason to do it is if one lives in a carb law state like me in cali or ny.
This just makes me want an LS even more than I already did.
Yes 👍 I've been waiting for the 5.7 Exclusive mods. I'm still working parts out in my head. I really need to know witch Cylinder heads will give me FULL POWER ,in conjunction with a Elgin sloppy stage 2 and fast intake .Thanks again , your a big help .🥳
there is no specific head that works with that exact cam-any ported head is going to do well (watch the head test vids)
Texasspeed 5.3 heads stage 3 are a good budget head to go with your budget cam and will give you a compression bump.450hp wheel with magic stick 3 camshaft

Thank you for the video from Australia, we promise to leave you alone now😉
Please don't-how else will I get updates on the Saltys and King Browns?
That old XR275 cam still works good, not a huge cam by any means. I put that same camshaft in an LQ4 with a TBSS intake, 92mm TB, and LT headers. It's stuffed in a GMT800 RCSB truck, runs really well and wants almost 6500 RPM at the peak. I believe it peaked at 6200, and wasn't down much more than 8-9 HP at 6500.
Appreciate you for doing this video Richard..the OG 5.7 ls1 is the equivalent to your junkyard 4.8 and 5.3 which we never got here as we simply didn’t get any trucks with LS motors in them ..we got ls1,2,3 only
they all respond the same way
I learned I need heads and a Fast intake. Running a 227/235 .618/.605 110 LSA cam with stock heads and an LS6 Intake. Richard making me spend money as usual. 😂
Thanks you Richard for another great video.
Cool look back at the LS1. You can build one today by boring an L33 to 5.7 bore, about 3.900+/-. The interesting point I got out of this test was the OG FAST intake with the RHS heads and the little cam did way better than the Edelbrock intake with the 459 cam in the (apparently) same long block. In fact, those looked really close to 6.0 numbers. Those RHS heads must be very well matched to the FAST intake of old. If I were building one now I’d use the Dorman LS2 or a TBSS, whichever I could find/afford, maybe TFS 215s, and a medium-ish cam. Thanks Richard!
It's ok we're running out of ls1s now it's cheaper to buy the truck motors an bring them over but I still personally thank you as after watching all your vids all my LS powered cars run high 220 duration cams as I don't like giving up powered down low
We keep wanting to run our nose down at "only the LS1", but then you see all this power being made. The proflow was down closer to 15ft-lb at under 5500 over the truck intake, some might not think it's a big deal... The 50HP on the upper end is more important.
Rebuilding mine now with summit's drop rod and piston kit, Texas speed stage 2 turbo cam johnson lifters and some other good stuff
Got a link to those rods and pistons
Still have my 99 camaro ss i bought new. Now it makes 544whp 446wtq with a na 5.7 .
Hey Richard how about a 5.7 mashup? Not just American made five Points something liter engines but Toyota and Nissan as well. You're quite the magician let's see what you can do brother.
I love these LS videos, they’re super entertaining. Could you do a video on the Nissan titan 5.6 dohc motors? They’re starting to pop up in junkyards more and more frequently and they’re a very very well built engine block.
The thing is about them there's almost 0 aftermarket support for them all you can realistically do on them is port the heads intake manifold and throw some boost at them and that's kind of boring to just look at the same power curve higher up in the chart
Thank you man! Learned alot and what direction to go to.
I'm doing a swap with a low mileage 02 LS1 from a Trans Am (came from factory with the LS6 intake), so I really like seeing Richard toss an LS1 up onto the dyno as I'm still thinking about what mods I will do after the car is running. I really don't need to go for a bunch of power as the car should end up around 2400-2500 lbs , but will do at least a cam at some point and likely heads too.
If you can find a set of 243 castings just throw them on stock with a cam in the low 220s 600 lift and you'll be happy. AFR makes a budget casting that replicates the 243s basically but are suppose to be an improvement so I assume they're decent. Some PRC heads might be a good value too. 243s should be worth 15 hp over an stock LS1 head on a cammed engine.
AFRs are a lot better than stock 243 heads
@@richardholdener1727 I'm talking about the enforcer not the cnc heads. Enforcer heads are $609 ea. They state that they are an improved 243 based head.
Richard I run a 246-252 cam with 108lsa on a SBE Ls1 with flycuts and decked and ported heads with a carby never dynoed, I’d love to see real cams and tighter lsa as a test on a SBE I know it needs way more revs to make power bit wanted that oldschool sound
Probably have 600HP or more if everything is setup right. We'd like to hear about it.
Would love to see you build a high RPM 5.3 and see how close to 10,000rpm you can go! Love the sound of a screaming V8
My combo will be... sorta close. 5.3 bored to ls1 size, 3.26 crank, 12.9 compression, solid roller. Should make peak power in the mid-7k, cam and springs are set up for 8k+
THAT IS A 4.8L BORED TO LS1 SIZE

Awesome video as always. Can you recommend a cam for my 98 C5 auto? Going from perimeter bolt heads to ported 799's milled .020. From the LS1 intake to an LS6. Gotta keep the exhaust manifolds for emissions. Car already has 3.42 gears with a YANK SS3200. Daily driver/weekend warrior. I race it, but it needs to remain a nice driving car. Don't need all the chop. Dont want super high lift, or have to worry about P2V clearance. Just need more power without making it a pain to drive! Thanks.
send me an email-might have one for you or I'll steer you in the right direction-killerbe16@aol.com
Thanks really needed to see this.
@Richard Holdener Great video! Thanks for thinking of us Aussies! I was fascinated by your small cam testing. I have a 2004 5.7 with a TSP 216/220 .600/.600 112, heavily ported 241 heads and all the other usual bolt ons. However, I still run the LS6 manifold and TB as I was told I will probably make no gains with a Fast 92 with my small cam. Your results seem to indicate otherwise. Would you expect any improvement from moving to a Fast 92 and NW or Warr TB over the LS6? Or only worth it if you have an LS1 manifold? Thanks 👍
you will improve power with the fast, but the gains you get increase with more cam timing (a more powerful test motor)
@@richardholdener1727 Thanks! I was expecting small gains and it's an expensive mod down here, so usually reserved for big power combos but interesting that there should at least be some gains.
@@richardholdener1727 I have a 01 C5 with BTR stage 3 cam kooks headers long tubes full exhaust. Would a stock 706 head make more power then the stock 241's??
Richard I got my hands on a LS1 from a 2004 GTO and transmission. And it only has 40,000 miles on it. I would like to install a cam, heads and intake. I liked what I saw on this video. I’m putting this in my 1997 SS Camaro. What cam, heads and intake would you recommend?
for what power level and usage
@@richardholdener1727 for street and strip. I have all BMR Suspension front and back. I’d like to get about 450 to 500 HP if possible.
I’m swapping a 04 GTO LS1 into a old Yota only has a upgraded clutch/flywheel, injectors, Holley efi, cam, springs, pushrods. Trying to make an easy 500whp for now to enjoy still can’t seem to get an answer as to what else to do to make that. I thought of porting my own heads but seeing these videos just makes me so indecisive on making a choice. I want to be n/a for now too just so I don’t break the frame.
you won't make 500 whp with an na LS1-you will need boost or a bigger motor
@@richardholdener1727what’s the max a LS1 can truly handle n/a without boost? Is 450whp reasonable?
Check out moto IQ channel.. Supposedly 650 wheel horsepower naturally aspirated.... But don't know if it's authentic.... Very high numbers..
Dude , do a turbo test just for fun. I know these are weak compared to iron but I love my ls6.
I have run LS1s with boost
Richard. Thanks for the great content. I love watching your videos on cam and head comparisons for the LS1 engines. Would it be possible for you to do a dyno run on the com cams # LS3LX270 carb legal 210/218, against the stock LS1,LS6, and non-carb legal 212/218 cam. living in california is a struggle with upgrades and meeting compliance. Thank you.
THEY HAVE A CARB LEGAL LS CAM?
@@richardholdener1727 yes, released in 2017 com cams FSL 210/218, 570/541 lift, 118 LSA. Carb # D-279-13 claimed to be 50 state legal. Would be interesting to see what the gains would be staying legal

@butch4481 they have slight piston slap but I really didn't notice much on my 2002 Monaro.🍺🇦🇺
How much would a FBO LS1 make with stock cam and heads? Longtubes, FAST 92 intake/TB, under-drive pulleys, cold air, and of course a decent tune. Want a set of ported 243s next. My car is a daily driver so I want to keep the stock cam. Haven’t been on a dyno yet. None here in my area.
Great video! I just picked up an LS1 with an LS6 intake that im going to swap into my old DD Volvo wagon. On a dyno sim program I have I plugged in the numbers to find the best average hp cam from 2000 - 7000rpm and it gives me like a 217/223, almost identical to the old "California love" WS6 cam.
I think you will be left wanting more are you planning on doing heads or just cam there are a lot of good cams Texas speed has a lot to choose from and they have never let me down
I'd go with something upper 220s low 230s .600 ish lift 113ish LSA. That cam you mentioned probably isn't going to rev to 7k. With what I mentioned your probably around what most companies are calling a stage 2-2.5 cam. Any decent place should be able to spec or recommend something specific to your needs
217 cam with a stock head and ls6 intake will be making peak power a lot closer to 6000 than 7000 rpm
I have a 5.7 M6 with a TSP 216/220 cam and LS6 manifold/tb but also ported heads, peaks just under 7000 rpm (I shift at 7000 rpm). It's nice on the street. Was looking at a Fast 92 with NW 92 TB but tuner said don't bother. I am curious if it would add anything.
@@jamestoby2552 it would add power but you're looking at 1500 for the combo plus installation and tune assuming you don't do the install and I'd guess you would get 7-10hp with that small of a cam.
1997 Chevy Silverado 5.7 Vortec is a engine I wish he’d do a video on
did you watch the recent vortec-headed build video?
Excellent. Any chance you can discuss l76/77 motors with dod then Cam swaps etc, I realise it's not a common motor there

A video on turbo spool vs different upgrades such as cams and intakes might make an interesting video.
look at the change in na power-that tells you change in spool
I'm playing with a tired 99' Camaro with a stock ls1 but I think the heads were milled cause compressions around 11 to 1 and 3.42s I just swapped the blown t-56 for one outta 05' GTO so its geared Lil lower now. The car was supposed to be just a doner parts car But It feels really good just banging gears in just a stock n/a Camaro, Not like something thats overpowered, unreliable and unpredictable Kinda like driving go-carts. able to get lil rowdy with my young boys who love Burnouts peeling out and getting sideways. Like being at Disneyland. So the $3000 shitbox has kind of turned into my summer project. I'm gonna race my Buddys 2012 LS7 Corvette he paid $40k hes also the old owner of my car, His ls7 he has now dyno'd around 640hp. with a Cali cam, MSD Atomic intake, and its tuned. I know even with the spare parts I already have laying around (comp Xer 281,Ls6 intake, maybe the Ebay long tubes , HpTuners and some fatty Nitto drag radials) . I still have little to no chance So I gotta dig around my garage and try piece together my old NOS setup. try to make a100 shot and get some decaps tested, On the bright side he's a shitty driver and lil afraid of his pretty lil garage queen. It only has 10k miles in 12 years. So most likely sporting the original factory dried out tires . I just want to earn those bragging rights before that overpriced monstrosity drops a valve! lol
I drive a 2000 Z28 I bought new. I'm looking to possibly upgrade the engine during a refresh in a year or so as it has over 180K on the odometer. My question is, what can I do to the engine and not have issues with emissions here in Arizona?

Im in the process of rebuilding my lm7 5.3 into a 5.7 have some leftover parts. I was thinking stock ls1 intake ls1 heads ls6 springs &ls6 cam curious on what the numbers might be any thought? Also a big fan have literally watched all your videos especially the lt1 series.
I haven't seen a combination like mine yet to know what hp i should expect, LS-1 stock heads, upgraded valve springs, sloopy stage 2 cam, 1 7/8 headers and a 102 fast manifold
Probably 380-400whp
As a iron head porter i look at the LS1 and see the Ultimate top end and they Barely get by on compression .But The Runners are to big to be turboed or supercharged .
It was ment to be the Ultimate Naturally Asperated Race Engine .
You dont want to shave heads .
you want to shave block after stroking it 45 thousandths if valve clearance allowed
At 13 to 1 compression it would perform like no other.
Starting with 500 horse plus 650 lift bump stick better valve springs
Bored to max upping the tork .
it would even Devour the SB2.2
As a 355 reving high
There would be monsters around here lol
runners are too big to add a turbo or supercharger? big no there
Da fuq you talking about Willis
Need opinions on what cam to run in my C5 LS1 5.7. Im mainly going with full bolt one, but I want a cam that will give me good power mid to high, chops good, and is suitable for street/daily use, I like to drift sometimes.
Read that the 226/232 600 112LSA is a good choice can make great power not too big of a cam. The other is Texas speed 232/234 600 112LSA and last
233/239/600 112
those will be a little soft down low but make good mid-the high rpm power
@@richardholdener1727 but which one would you say would make the most sense in terms of making good high power?
So weird hearing LS1 OG / Old school.
Richard, can you make a video on that water pump? My group and I have been going back and forth on if it actually yields any power. I swear by them where as a buddy of mine claims the $500 isnt worth it.
the mechanical water pump requires power (PARASITIC LOSS) to produce the work (moving the water), DIFFERENT DESIGNS ARE MORE OR LESS EFFICIENT, an electric pump frees up some of that lost power
I’ve got a 5.7 GTO with 4.11 gears, building a try hard 1/8 mile car. Should i worry about torque? I’m hoping the gear set will make up for the lost torque if i go max power for the 1/8th. Not worried about drivability it’ll almost never see a stop light

Hi Richard. Do you think a stage 3 xe-r cam is too aggressive for the LS1?
show me specs-but if it fit available p-v-you can run it
@@richardholdener1727 It is an XER281HR-12c
I can't decide RHS or MAST?

What value are we using for Stock LS1 cyllinder heads flow? I keep seeing ( 220CFM for unported LS1 heads ):
Lit Intake Exhaust
.100 66 51
.200 140 94
.300 193 126
.400 210 150
.500 219 162
.550 223 167.
So when you put aftermarket heads in the combo we are assuming closer to 300CFM peak flow, usually past 280? At least 50 additional CFM? The camshaft on the stock engine showed 470HP/450ft-lb and with the aftermarket heads and aftermarket intake was able to do 550HP/490ft-lb a gain of 50-80HP over stock LS1 head.
stock LS1 heads flow more than that
Which casting? I'm seeing similar numbers for early castings, but i should have noted the casting number from this data.@@richardholdener1727
The data is from 853 castings off of a 1999. I'm looking at other flow data which is very similar to within a few cfm. @@richardholdener1727
Can't you bore the 5.3 to a 5.7?
yes-Westech has one of those
Richard. What was the optimal afr and how much timing did it seem to like?
there is no optimal AF-lots of ratios will make the same power but we run NA motors near 12.5:1, and 29 degrees of timing for NA LS motors
Thanks, Richard. That's what i wanted. I'm just looking for somewhere to start. I have an og ls1 with lingenfelter gt12 cam and stage 1 cnc ported 799 heads. Cam is 227/235. 621/657. Have 6014 with dual plane intake and 750 hp holley.
Sweet. I got a 6.0 and recently a ls1. My ls1 seems to respond better down low with it's 862 heads than my 6.0 and ls3 heads. Both have 273 gears both are in 01 camaros but the ls1 car had a built 4l60 vs the 6.0 with a 4l80, same 3600 stall rating.
My 6.0 gets stomped in the 1/8th and 30 roll, but on the hwy it's pretty even till about 80mph then it's no contest. Oh and the same 228 cam
Man your two Camaros are similar to one of his tests comparing the heads!
Are both tuned?
4l80 might be part of the issue. Taller first gear, much heavier, and because it is so much beefier parasitic losses are higher. Biggest thing is probably the gearing though. Stock 4l80 gearing is not very friendly to cars without big hp numbers.
@@danholmes1522 the one with the 6.0 is tuned the ls1 car needs more tuning. Forgot to mention that. Needs about 3 degrees more timing.
Definitely the transmission is the difference.80s first gear is tall and long eats a lot of power.60s are weaker but man they don’t rob any power and with any gear it will chirp the tires. Put 410 in the 60 and it will feel like you added 100ftlbs of torque
Rich are you in the Bay Area? And do you tune cars??
I am not a tuner
Richard i ask you test Power Products LS1 heads they are 212cc/76cc with 57 cc chambers
never heard of them
Yessss.. 5.7! Spec'd out mine recently. Wish list is ARP fasteners, FAST intake/TB, TEA ported 241s, & a comp 227/235 cam 🤤 go go Camaro!!
You da man Richard!
that would be a good combo
Get the magic stick from Texas speed
So if you take two naturally aspirated engines of the same displacement, one stock making 200hp and a built engine making 400 hp, you take a turbocharger and put it on the 200hp engine with 15psi of boost to make 400hp, is the engine that’s boosted under more stress just because of the boost or are the two engines under the same amount of stress?
The boosted one I'm sure has more stress cause of the boost applied., been wrong before tho lol...Both will have stress applied at some level...at w.o.t honesty
The boosted engine is under more stress. Both engines NA are under 1 bar. For the 200hp motor, when you add 14.7 lb of boost to make 400hp. Now that engine is under 2bar. 1 atmospheric and 1 bar psi.
don't know what you mean by stress
@@richardholdener1727 I figured you’d say that but I had to shoot my shot.
@@tomcelica What are you most worried about? Scuffing pistons? Valvetrain failures? Rod failures? Blown head gaskets? the NA 400 HP engine will be under more stress due to higher operating speed, and the boosted 400 HP engine will be under more stress due to higher operating pressure.
Did I shed a lot of dark on the subject?
I learned that my ls1 should be making over 600hp na lol.
that would be a lot for an LS1
I’m sure it’s not making that kind of hp, I feel like I could run a ported msd and get way closer. Mods are ported fast 102, trick flow 215’s, solid roller 244-253, 109 Lsa, 680 lift. Fly cut pistons, Ewp, arh 1-7/8 headers.
I'm now Australian 😎
Aussie Aussie Aussie
Oi Oi Oi
Soooo close. I asked for the ls4 yesterday not the ls1 lol
It would start at 800 horse and just go up
ALL your video's need the engine noises. Laughing my ass off every time
Lol, "motor motor motor"...
