Nah, a small bore sucks for power production. IF the 305 had a larger bore and a shorter stroke from the factory, THEN it would be worth the time and money. Otherwise, just start with a 350 block
@@davelowets if you're gonna build it then definitely! For me though keeping it cheap so I can drive it and not cry about gas costs like other garage queens that never see the outside world is important and every single time the 305 will get you 100 hp cheaper than just about anything! Put that in a 30s coupe and the weight to hp works out great! If someone is whining about too much weight then stop driving a garbage barge.

I love my junkyard 305 I built 16 years ago. 77 Nova flat top engine, late 80's swirly heads kitchen table ground for more flow with an edel brock performer cam and TPI, it moves my 83 Firebird out of it's own way very nicely. I can keep up with modern Mustangs.

i had a 89 camaro years ago. it had a 305 TBI, i swapped in a 350 TBI and it still didnt have the power i wanted. i ditched those swirl port heads and it woke up. it had a bored throttle body, the correct PROM, a high flow fuel pump and short tube headers
We have a 5 litre 308 here in Australia with a 383 stroker they can make up to 650 bhp . And they can stay together for years with the right love and care.
Waste of money building a 308 for a HQ, unless it's a matching number 81837 You still end up with a 308. Spend the money on big block and wave goodbye in the rear vision mirror
This is without a doubt the best small block program, based on the one that no one wants 305 and that is available to everyone lying around in many places, now add a blow thru carb, and shut up once again those who criticize 305, cheer up guys.
My Dad and I test drove brand new Chevy Monza's with the, then new, 4.3 liter 262 Small block V8's and 4 Speed's. They were gutless so we ended up buying a brand new Oldsmobile Starfire Firenza with the 305 V8 and the 4 Speed. It was a blast to drive and much faster than the 262. Oddly we also test drove the new Buick Skyhawks but they had the 231 V6 engines that would end up in Dad's 87 Buick T-Type Grand National much later, but with a Turbo and intercooler.
It would be better to start with an engine that was already kind of hot from the factory, 283, 327 or 350. The 305 is a smog motor created in the malaise era from the 350.
That video is awsome! 511 HP out of a 305 (oh wait pardon me, 340 ci block) is stunning. Anybody would be proud to have that engine under their hood. Great job!! Very educational!!
@@Anarchy-Is-Liberty I agree. Pretty dumb way to spend 10 grand. Could have just shoved a big cam and springs in an otherwise stock 5.3 and made the same power for around $500 in parts.🤣 The fact that they had to spend that kind of money just to make Cam only LS power tells you exactly why nobody wants a 305.
Amazing build. For those of us that still rely on 1st gen small blocks for their hot rods this was awesome. Imagine a numbers matching late 70's early 80's Camaro that came with a 305 with this build up under the hood.
Had a HO 305 tuned port injected 87 IROC I always wanted to pull the 5.6 out of my truck purt the tbi on it and throw it into the the IROC my 5.7 was pulled from a suburban originaly. Have 2 307's to build and then onto 3 1500cc mg midget engines to build.

It's nice to see what this combo can make with a better cam, heads and comp ratio. Well done! These little mice can make power. My little stroked +.060 305 (I called mine a 339 as to not confuse the mopar guys ) has Speedmaster 195, 2.02/1.60 heads, summit 1107 hyd flat tappet cam, 1.6 roller rockers, same DSS racing pistons except the flat tops, 6"I beam rods, and OLD School Edelbrock Victor 4+4 intake.

This is awesome! Nice to see an engine build that’s out of the typical sbc/ls platforms! Never once considered the potential of a 305 but that’s why you guys are the experts and not me 😂 great work as always Pat and Frankie 👍🏻
@@AndrewDRoyappa I meant just different from the typical 350, 327, etc. The 305 is kind of the redhead step child, don’t hardly ever see anyone building them
Have a 78 Regal with 425,000 on its 305 with original pistons. Have owned it for 29 years. Runs like champ and has been the most reliable engine I've ever owned. I'm a Ford guy but I love this little Chevy.
That 305 didn't listen to the hype....it didn't care if it was a 400 or god forbid an LS/1/3/5/99x...it just did it's job and got you where you told it to go. Who has it better than that.....NOBODY!
Man all these parts and labor ain't cheap! You're sponsors deserve a hug, maybe a couple! Thanks fellows for what you do! Excellent show! Good and clean!!!!
If you want greater success extracting broken bolts using the nut welding method, you have to remove the zinc plating on the nut first. I drill out the center of the nut, and sand off the plating on the surface facing out and it works much better.
The next step up is to weld a washer to the bolt first then a nut to the washer and bolt, better chance of fusion that way with the cheap mig welders most guys are using. Most guys cold lap for the first bit due to too much stick out and not enough heat and don’t get any fusion to the bolt and the nut just comes right off until they get it hot enough after 10 attempts to actually fuse somewhere
I had a bone stock 305 in a new 86 Silverado. It was a gutless dog but tuff as a bull pup. I put 140K carb'd miles on the motor and it, rand it hard, and it never failed. It ran like new when I sold the truck. I didn't like it but I admired the durability
Wow! Beautiful a story and I'm looking forward to to completing the process of seeing what is done! In the late 1960s I put a 327 and a 283 together and began a hobby, sometimes quite expensive, which has not left me yet, though I'm happily pursuing (at 80 years of age disappears to be totally appropriate). longevity and good function rather than short-term go fast!😅
For people looking for lightening the reciprocating weight, use 305 rods, theyre lighter as are the counter balancers on the crank. That boys and girls is what a stock circle track engine builder, a winning one, does on 350's to help them rev quicker off the corner, and that wins races.
Personally, I think what hurt the reputation of the 305 had a LOT to do with the emissions equipment and tunes from the factory compared to the effect the emissions equipment had on the 350. The quick route to more power was to throw in a stock 350, and, if you could get one with a 4bolt main, that was a bonus. Since you also already had the 350 out of the car, it was a simple job of throwing in a new cam and heads for even more power.
@@Nowayjose-z2r The last year of the 307 was 1973, when it put out a whopping 115hp, if it didn't have emission controls then I don't know what FM did wrong.
LMAO 305 and 350 sbcs of similar years have the same emissions equipment. Wonder how many folklore and misinformation you had to dredge through to come to that conclusion
4 bolt main wasn't really a bonus unless you planned on building it for ungodly amounts of power and revving the piss out of it, 2 bolts are strong enough for up around the 1000 hp area.
Definitely, and not immediately ditch the TPI setup for a better flowing carb. What kind of power can you get out of the TPI? Maybe setup the engine for more of a torque monster than trying for peak hp.
Those engines were so anemic doubling the power wasn't very hard to do. My dad had a 305 in his 79 Monte Carlo that he rebuilt and it was weak. I can still remember him saying he should have built a 350 instead.
I had a 1979 GMC Jimmy with a gutless 305... so worn I added oil when pressure dropped to zero... ignition was messed up and it would backfire and about blow the engine apart... it was a mess! That Jimmy was our deer hunting field truck... it got flogged across plowed fields at 50mph...
I thought the same thing but when you take the cam, big headers, and hi flow heads you can get it climbing up to 7k and the higher spin is what is netting higher power numbers
@@Anarchy-Is-Liberty . . that's not the point, even though you make a good point. The point of the video was to show that the same improvements and modification will work on _Almost_ any engine. But yes, it's impractical, from a financial standpoint, to put that kind of monies into that particular engine.
@@jamesmedina2062 To be blunt.. gobs of torque!! Torque combined with horsepower is what makes things move, and move fast! Do the same exact build on a 305 and on a 400, and see what happens. The 400 will make approx. 65lbs ft more torque. It will lose about 8-10 hp on the top end, but the torque gained will win the race. Another benefit is, because the 400 has way more stroke, it moves the power band lower. So the 305 would operate (with a cam of 235 degrees duration @.050) from 4500-6500+ to the 400's range of 3500-5500+. Added benefit of being easier on parts, and longer lasting. Now, to make it actually fair, you could add another 0.1 to the rocker arm ratio (from 1.5 to 1.6), which would bring up the 400's hp and trq numbers even more. Because the engine has more stroke, that cam would actually be much smaller to the 400, so you could also use a bit larger cam to make up the difference. To bring the 400's rpm range up to that of the 305's, you'd want a duration @.050 of approx. 255, and about another 0.030 in lift (to stick with the original 1.5 rocker ratio). This would bring the 400's rpm range up near the 305's from 4500-6500+. Not only that, now you're making at least another 20+hp on top, and overall more torque throughout the rpm range. The cherry on top with the 400 now is, you're making in the neighborhood of an extra 15-20lbs ft of torque on the top end combined with the added hp, so massive power difference all the way around. Either way, I stick to my original comment... the 305 is a totally impractical build! Now, if you want to build it just because you want to, that's fine, it's your life, live it, I wont hold it against you, but it's still a totally impractical build. A V8 is a V8? Then why aren't people all racing with 283's instead of building 632's, and now over 900ci race engines?
Boy this is some kinda handy. I got rid of my last 305 at 19, it was a gutless TURD! Haven’t owned one since. But if I had know all this then I maybe could have had some heart in that old ‘81 Chevy single cab step side.
Awesome build! I have a 305 in my 77 Firebird Esprit! It was rebuilt before I bought it. The guy who re built it, put a truck cam in it. From what type of truck, IDK!! It also has been upgraded from the stock 2 barrel to a 4 barrel Edelbrock 600 cfm carb and manifold. I dont have any performance numbers on it , since the upgrades. Love the work you guys do! Keep it up!!
@@macthemec It's been used for years in forklifts. Inside many forklifts is a Chevy 4.3L V6 engine. Same with propane & natural gas used in generators. Many semi's use a combination of diesel with propane injection. If propane costed the same as gasoline mile for mile. An engine is way better off burning propane than gasoline.
I gotta tell yall. I found a low hour very good condition boat motor SBC that I thought was a 350. I just last week found out through the casting number it’s a 305 and I was disappointed and then yall drop this video 😂😂😂😂 insane timing! The car gods want me to drop it in my 93 Sierra after all 💪🔥
Just get a 350. You will pay the same to build and the 350 has more to offer. Actually the 350 can get 500hp for less money. Only use the 305 if you just need a engine to get by.
@@Soundsofthewood I’ve been told that and I do get it. But this boat motor was $free.99 and it’s already got forged internals and a cam. Also not really worried about making insane horsepower. If I copy the rest of this build from the heads up and get close to 400 or more I’m happy. 💪
BOP, BUICK OLDSMOBILE PONTIAC in respect made more power than the Chevy engine in 95% of stock forms, the Chevy is the clear winner in horse power per dollar in the aftermarket world
After having several Chevy small blocks, I bought a cutlas supreme with a 350 rocket, never went back to Chevy! That rocket has been my favorite of all time!
My dad's 1986 chevy c10 had a 305 and it lasted more than 300,000 miles original and it still ran good all the time. So 38 years later it's getting a new 350 with vortec heads and a freshly rebuilt transmission.
Awesome 305 build! LOVED IT!! My 1st driver was Dad’s ‘84 C10 I took over. I cut my teeth on street racing that ole truck. I finally blew the motor & had another 305 w/a Perfect Circle cam (292 dur, .502” lift), Holley Contender dual plane intake, full length headers, & a Carter 750cfm carb. Factory 3:08 gears & factory torque converter on a 700R4. Beware of bicycles up to 3,500rpm!!! It’d flat pull after that!!! Needless to say, I cracked every piston n that motor. Awesome memories while it lasted though!! 😁
I got a 305 as well, absolutely love it and was waiting to watch this episode because of the data one can learn from this. Yeah it’s cool to hop up a 305, but most are driving between 2000 and 3000 rpm, kinda disappointed at the power band within that rpm range, but overall I’m glad all did this pretty interesting
I got to give it to you. I put off watching this thinking the same thing. 305? Then Pat goes into a Honing tutorial! This is what I want from my machinist. Excellence! Of course, as a builder, you must inspect and verify. Great knowledge, you can find them anywhere.
This proved what I've been telling all these young engine guys that think they tested a 327 chevy, Unless you were alive in my era you don't know about the cars or engine perfomace of my era !! If you test a 327 you'll need to test it right. leaded fuel (103 to 107 octane fuel) and high compression (11 to 1 or 12 to 1) and headers Some of the same engines ran better because the automobile industry wasn't perfect. Thank you Powernation for opening some people eyes.. But most us knew that 305 was in the 265 family.
I have two 305 engines with mod cams and headers that run great. 350 where hard to find and people practically gave me the 305 motors. I love 'em. I never wanted more power and my 40 chevy has been on the road since 1996 with no trouble, no over heating and enough power to spin the tires on the 1-2 shift.
I really like the ease of how you guys do this and seeing the equipment that's pretty much automated is awesome. Always feels like I'm watching The Truman show movie with ad placements sprinkled throughout
I love this video. Where were you guys 25 years ago? I could’ve used your help back then when I was rebuilding my 305. Better late than never, I suppose. Thank you for making this video.
👍 Thank you for using one of those LS firing order camshafts for the small block Chevy. I've been anxiously waiting to see what those sound like and how they perform. It just would have been nicer to see somebody using it on a more commonly used 350. But that's okay, I'll take what I can get.
@@Torquemonster440 I never said it wouldn't. I'm politely implying that's it's a waste of time putting it in this boat anchor, but thanks for playing. 😁
I build a lot of streetable 335 strokers from the 305. Everyone's favorite is the 305 block with a Dana internally balanced 400 crank , trw ceramic top pistons, Bolin rods edelbrock airgap intake and 202 heads. 525 hp 477 torque. I also build a 357 copo style 350 that's 357 hp. 310 torque that's a great motor for your old square body trucks.
@@pastorjohnculbertson661 ah , those 2486 pistons are a 1.56" comp height piston, so you must be using 400 rods ..... and that internal balance crank is gonna be swinging some pretty big counterweights which are not 400 rod compatible ? so how are you making this thing fit together ?
@luckyPiston My in-house lead man worked with team force for 15 years he is a wiz at wringing out every ounce of horse power possible out of a motor. We're working on doing a full video build of a 335 stroker/ blown hitting 600 horse.
The 96 and up Vortec 305s are a fantastic engine. I dropped one in my 86 GMC after i messed up the 350. The 305 was free, so i figured it would be good till I fixed the 350. That was 10 years ago, lol. I used a edelbrock performer knockoff intake and the original Qjet. Headers and 2 1/2" dual exhaust woke it up.
I have yet to see you guys run a 327. Start off with the best heads (double hump) from back in the day (maybe ported and a good port matched intake) put flat tops in that makes about 10 to 1 with a dutnov grind 30/30 cam and a 650 carb. Then build it again with a lighter forged rotating assembly with lighter rods and pistons and good hardware. 11.5 to 1 compression is completely doable with aluminum pistons and heads with mls gaskets. Stick a healthy sollid roller cam to make power to about 7500-7800 rpms. Get a good set of AFR heads and a fully ported and polished edlebrock rpm intake with a carb spacer. Playing with different styles and widths could make good content then try a as cast vic jr then one with just the ports cleaned up both port matched to the AFRs of course. This could be a three part series. 1st Run the first engine with 91. 2nd the new combo and fully ported rpm air gap and different spacers with 91+race gas octane booster. 3rd with the vic jr as cast 91+ booster and then ported with race gas. It would just be cool and very interesting and enlightening to see/compare the difference hp/trq numbers to give people an idea where they could potentially save a lot of money and still make good numbers or if its worth spending just a couple hundred bucks and make awesome power. You guys do too much LS stuff and dont get me started on how many different small and big block Ford combos you've done.. By far and away the 327 has been snubbed by powernation for more than a decade! Time to show this forgotten gem some well deserved attention! I mean you guys have litteraly done 283 350s maybe 377 383s 400 and 400+ cubic in small block chevys but never a 327 to my knowledge.
Wow! That was a super cool episode. I was a little leery at how long it was but, it was well worth the time. I love how you all took it from mild to wild too. Outstanding episode guys.
I had an 81 Chevy truck 305 granny 4 speed I ran the piss out of that 305 it went 200,000 miles we pulled rebuilt it and put it in another Truck and is still running today from 1981 to 2024
I really appreciate the straight forward presentation without the over the top personalities. Some of those guys on these shows are so cringe it's impossible to watch the program. So again, thank you guys. This doesn't give me second hand embarrasment.
I just sold my 58,000 mile numbers matching 305 out of my 1985 Z/28. And bought a 5.3 LS I guess I'll stroke that and kick myself at the same time because something told me as soon as I sell this engine technology was going to catch up to this motor and do something awesome.... Thanks Pat & Frankie!!!!
Really they are mainly seen being used in certain stock car racing classes. I have seen them at the shop with splayed caps and built up pretty powerful running high rpms and living just as long as the 350 engine. Interesting video for sure but I am a big block chevy/ford guy for life 😂
The BBF/BBC are no joke, but lil engines do hurt big block engine's feelings at times.. i too am a big block guy myself, can't beat the raw power they make in n/a form..
Proof that with enough money, any engine will make power. I've never had a problem with the 305. Just a good, durable engine that was strangled to meet emissions
If you have a 305 in your own car this series makes a TON of sense to me. The 305 was around during the decades when fuel economy was being strictly mandated for the first time and there were no quick answers, so people talk about it like the engine sucks. There's nothing wrong with 5L of displacement if you just let it breathe.
You are the dream guy that I would love to have honing the block of my 383 build. I had to settle for a local machine shop, so wrenches crossed she is straight.
Cool video but i would have liked to see the stroker with the same heads/cam as the first build so we could compare stroker vs non stroker power directly
I can already tell you what would happen. It would lose horsepower and gain torque, which in this case would probably be a good thing, being it's going to go into someone's street beater.
Anyone on planet earth can find a hyd roller 350 core motor for $500. Why would anyone in their right mind spend massive $$ to stroke a 305, then be stuck with small-bore heads?
@@JS-kd7jf No, this isn't opinion. Compare a 3.75 stroke 305 to a stock 350. The 305 based engine will require heads that cost more and flow less because of the small bore
My Dad replaced the 4.3 V6 out of his '88 Chevy Cheyenne with a 305 from a '79 El'Camino, which came with the transmission also. That truck would still be around, had he swapped the rear end for a 12 bolt. Or at least changed the diff fluid a time or two....lol. But that 305 really livened that truck up, along with that transmission.
I have a 307, with forged pistons, moly rings, windage tray, 2X hump heads, solid lifter fuelie cam, 700 double pumper, etc. 7,000 rpm almost daily. Never let go.
Awesome project!! Grew up with these being a boat anchor. Do own one on propane sitting in an old school bus. Itching to pull it and make it more efficient. But to see parts off a counter make over 500 horsepower is great. Great job, hope to see a chevy 302 come up
I am a guy born in the early 70's and teenage muscle car, gear head days were the 80's. I can tell you my older gear head cousins always said they were throw away engines and not worth doing anything with. I did always find it funny that the holy grail small block chevy was a 302 and everybody ragged on the 305. Anyways, its nice to see that the 305 is not a throw away and it can make some really good numbers!!
Glad you did something different with a 305. I remember there was tons of them back in the day. Choked down with smog stuff
Great to see someone doing something with the forgotten 305 chevy

We have a 5 litre 308 here in Australia with a 383 stroker they can make up to 650 bhp . And they can stay together for years with the right love and care.
The plastic engine struggles at 3.5" stroke so any bigger is a real worry. And going that big means the heads are totally inadequate.
Yeah, but it's a shed-load of work and $$$s - and depending on the specific engine used for the build base, there are still some base weaknesses.
Your right ,about $12000 here in oz but like I said love and care . But you could say that about any motor .
Waste of money building a 308 for a HQ, unless it's a matching number 81837
You still end up with a 308.
Spend the money on big block and wave goodbye in the rear vision mirror
Is it a Chevy/ GM engine...?

305, 307, the same as 283, 327, etc. So why not? Cool build. Who doesn’t want a 500 hp hot rod!
I came here for this comment. Lol. 283 family has multiple common cubic inch sizes.
The only issue with the 305 is the odd bore size. Thats a large reason no one builds them.
My Dad and I test drove brand new Chevy Monza's with the, then new, 4.3 liter 262 Small block V8's and 4 Speed's. They were gutless so we ended up buying a brand new Oldsmobile Starfire Firenza with the 305 V8 and the 4 Speed. It was a blast to drive and much faster than the 262. Oddly we also test drove the new Buick Skyhawks but they had the 231 V6 engines that would end up in Dad's 87 Buick T-Type Grand National much later, but with a Turbo and intercooler.
Yo momma? IDK, maybe you've got a cool momma!
It would be better to start with an engine that was already kind of hot from the factory, 283, 327 or 350.
The 305 is a smog motor created in the malaise era from the 350.

Thank-you for Listening to us we're your customers too!. That is on the 305 build. Glad you are taking the time here US.
If you want greater success extracting broken bolts using the nut welding method, you have to remove the zinc plating on the nut first. I drill out the center of the nut, and sand off the plating on the surface facing out and it works much better.
Heck yeah. Good advice.
The next step up is to weld a washer to the bolt first then a nut to the washer and bolt, better chance of fusion that way with the cheap mig welders most guys are using. Most guys cold lap for the first bit due to too much stick out and not enough heat and don’t get any fusion to the bolt and the nut just comes right off until they get it hot enough after 10 attempts to actually fuse somewhere
I had a bone stock 305 in a new 86 Silverado. It was a gutless dog but tuff as a bull pup. I put 140K carb'd miles on the motor and it, rand it hard, and it never failed. It ran like new when I sold the truck. I didn't like it but I admired the durability
I had an 86 Silverado, first the 700r4 went, then the 305 spun a rod bearing. 3/4 ton with 4 bbl 305, 700r4, and c clip 14 bolt. Worst of everything.
@@randymagnum143 A 3/4 ton never should have came with that engine.
Wow! Beautiful a story and I'm looking forward to to completing the process of seeing what is done! In the late 1960s I put a 327 and a 283 together and began a hobby, sometimes quite expensive, which has not left me yet, though I'm happily pursuing (at 80 years of age disappears to be totally appropriate). longevity and good function rather than short-term go fast!😅
For people looking for lightening the reciprocating weight, use 305 rods, theyre lighter as are the counter balancers on the crank.
That boys and girls is what a stock circle track engine builder, a winning one, does on 350's to help them rev quicker off the corner, and that wins races.
Personally, I think what hurt the reputation of the 305 had a LOT to do with the emissions equipment and tunes from the factory compared to the effect the emissions equipment had on the 350. The quick route to more power was to throw in a stock 350, and, if you could get one with a 4bolt main, that was a bonus. Since you also already had the 350 out of the car, it was a simple job of throwing in a new cam and heads for even more power.
What really hurt it was displacement;. Otherwise the 307 would arguably been better as it had no emissions.
@@Nowayjose-z2r The last year of the 307 was 1973, when it put out a whopping 115hp, if it didn't have emission controls then I don't know what FM did wrong.
LMAO 305 and 350 sbcs of similar years have the same emissions equipment. Wonder how many folklore and misinformation you had to dredge through to come to that conclusion
They both made abysmal power, in the pickups some years of the 305 made as much or close to same power as the 350, bother were around 165hp
4 bolt main wasn't really a bonus unless you planned on building it for ungodly amounts of power and revving the piss out of it, 2 bolts are strong enough for up around the 1000 hp area.
I'd love to see what you guys could do with a 305 with TPI. See how much power you can get out of a "stock" setup from the 80s.
Definitely, and not immediately ditch the TPI setup for a better flowing carb. What kind of power can you get out of the TPI? Maybe setup the engine for more of a torque monster than trying for peak hp.
33 years ago I built the 305 in my 84 Malibu. RV cam, the HO 305 heads, flat tops, gutted the cat. Easily doubled the factory horsepower.
Those engines were so anemic doubling the power wasn't very hard to do. My dad had a 305 in his 79 Monte Carlo that he rebuilt and it was weak. I can still remember him saying he should have built a 350 instead.
So, now you have 240 horsepower?
@@davelowets, I think closer to 280.
And still lost to bone stock 5.0s lol
@mattipps no 😂 5.0 had 140 hp what are you talking about fordboy?
That's awesome never expected that outta a stroked 305 nice. May not be practical but It was nice to see
You should see how much the sprint car guys get out of a 305 stroker with a hilborn setup
I had a 1979 GMC Jimmy with a gutless 305... so worn I added oil when pressure dropped to zero... ignition was messed up and it would backfire and about blow the engine apart... it was a mess! That Jimmy was our deer hunting field truck... it got flogged across plowed fields at 50mph...
In the past, if someone said, " I have a 500hp 305" I would have laughed at them before calling them a liar.
from 200hp to 500+hp . . . That's some serious gains! . . . there's No Shame in Those Gains ! ! !
I thought the same thing but when you take the cam, big headers, and hi flow heads you can get it climbing up to 7k and the higher spin is what is netting higher power numbers
You could have spent the same money on a 406, and made way more power overall!! Totally impractical build!
@@Anarchy-Is-Liberty . . that's not the point, even though you make a good point. The point of the video was to show that the same improvements and modification will work on _Almost_ any engine. But yes, it's impractical, from a financial standpoint, to put that kind of monies into that particular engine.
@@Anarchy-Is-Liberty A V8 is a V8 and with good flowing heads and bottom end parts, what is the big difference? What advantage would a 406 yield?
@@jamesmedina2062 To be blunt.. gobs of torque!! Torque combined with horsepower is what makes things move, and move fast! Do the same exact build on a 305 and on a 400, and see what happens. The 400 will make approx. 65lbs ft more torque. It will lose about 8-10 hp on the top end, but the torque gained will win the race. Another benefit is, because the 400 has way more stroke, it moves the power band lower. So the 305 would operate (with a cam of 235 degrees duration @.050) from 4500-6500+ to the 400's range of 3500-5500+. Added benefit of being easier on parts, and longer lasting.
Now, to make it actually fair, you could add another 0.1 to the rocker arm ratio (from 1.5 to 1.6), which would bring up the 400's hp and trq numbers even more. Because the engine has more stroke, that cam would actually be much smaller to the 400, so you could also use a bit larger cam to make up the difference.
To bring the 400's rpm range up to that of the 305's, you'd want a duration @.050 of approx. 255, and about another 0.030 in lift (to stick with the original 1.5 rocker ratio). This would bring the 400's rpm range up near the 305's from 4500-6500+. Not only that, now you're making at least another 20+hp on top, and overall more torque throughout the rpm range. The cherry on top with the 400 now is, you're making in the neighborhood of an extra 15-20lbs ft of torque on the top end combined with the added hp, so massive power difference all the way around.
Either way, I stick to my original comment... the 305 is a totally impractical build! Now, if you want to build it just because you want to, that's fine, it's your life, live it, I wont hold it against you, but it's still a totally impractical build. A V8 is a V8? Then why aren't people all racing with 283's instead of building 632's, and now over 900ci race engines?
Boy this is some kinda handy. I got rid of my last 305 at 19, it was a gutless TURD! Haven’t owned one since. But if I had know all this then I maybe could have had some heart in that old ‘81 Chevy single cab step side.
Awesome build! I have a 305 in my 77 Firebird Esprit! It was rebuilt before I bought it. The guy who re built it, put a truck cam in it. From what type of truck, IDK!! It also has been upgraded from the stock 2 barrel to a 4 barrel Edelbrock 600 cfm carb and manifold. I dont have any performance numbers on it , since the upgrades. Love the work you guys do! Keep it up!!
So does it have any nuts?
Thank you for this truly lovely build up of 305cid!
Go Pat and Frankie! Do an episode on dynoing a propane-powered engine!
It'll have slightly less hp but the engine will last 2 to 3 times longer along with the benefit of needing fewer oil changes.
@@michaelbrinks8089propane is the equivalent of 100 octane gasoline, its got potential as a fuel
@@macthemec It's been used for years in forklifts. Inside many forklifts is a Chevy 4.3L V6 engine. Same with propane & natural gas used in generators. Many semi's use a combination of diesel with propane injection. If propane costed the same as gasoline mile for mile. An engine is way better off burning propane than gasoline.
Just figure on losing about 30 to 40ish hp overall with propane.
"Many" semis don't use that at all lol. It's VERY rare.
I gotta tell yall. I found a low hour very good condition boat motor SBC that I thought was a 350. I just last week found out through the casting number it’s a 305 and I was disappointed and then yall drop this video 😂😂😂😂 insane timing! The car gods want me to drop it in my 93 Sierra after all 💪🔥
Just get a 350.
You will pay the same to build and the 350 has more to offer.
Actually the 350 can get 500hp for less money.
Only use the 305 if you just need a engine to get by.
@@Soundsofthewood I’ve been told that and I do get it. But this boat motor was $free.99 and it’s already got forged internals and a cam. Also not really worried about making insane horsepower. If I copy the rest of this build from the heads up and get close to 400 or more I’m happy. 💪

BOP, BUICK OLDSMOBILE PONTIAC in respect made more power than the Chevy engine in 95% of stock forms, the Chevy is the clear winner in horse power per dollar in the aftermarket world
How about a 550" big-block Olds? With the aftermarket block and billet cranks available today, the big Olds can produce some SERIOUS power.
After having several Chevy small blocks, I bought a cutlas supreme with a 350 rocket, never went back to Chevy! That rocket has been my favorite of all time!
I've got several 305 engines thanks to my Thirdgen F-Body love. From factory q-jet to TPI, and love seeing this episode.
One of the best looking motors you guys have done, she's beggin for a turbo
Yes
Considering how much they got out of the 4.3, it's power level should be pretty good
If that turbo 4.3 was available and for sale, I would seriously consider buying it.
My 75 Monza 2+2 would love it.
Already pushing the power limits on a 2 bolt main block, turbo would absolutely grenade it at that point!
In the late 1970s Accel made a bolt on turbo kit for sbc. Put one on my G20 Chevy van and it was fun!
Right out the gate, I was surprised by the HP on the 305, I was thinking something more along the lines of 350hp not 400hp+

Awesome 305 build! LOVED IT!!
My 1st driver was Dad’s ‘84 C10 I took over. I cut my teeth on street racing that ole truck. I finally blew the motor & had another 305 w/a Perfect Circle cam (292 dur, .502” lift), Holley Contender dual plane intake, full length headers, & a Carter 750cfm carb. Factory 3:08 gears & factory torque converter on a 700R4. Beware of bicycles up to 3,500rpm!!! It’d flat pull after that!!! Needless to say, I cracked every piston n that motor. Awesome memories while it lasted though!! 😁
I got a 305 as well, absolutely love it and was waiting to watch this episode because of the data one can learn from this. Yeah it’s cool to hop up a 305, but most are driving between 2000 and 3000 rpm, kinda disappointed at the power band within that rpm range, but overall I’m glad all did this pretty interesting
I got to give it to you. I put off watching this thinking the same thing. 305? Then Pat goes into a Honing tutorial! This is what I want from my machinist. Excellence! Of course, as a builder, you must inspect and verify. Great knowledge, you can find them anywhere.
This proved what I've been telling all these young engine guys that think they tested a 327 chevy, Unless you were alive in my era you don't know about the cars or engine perfomace of my era !! If you test a 327 you'll need to test it right. leaded fuel (103 to 107 octane fuel) and high compression (11 to 1 or 12 to 1) and headers Some of the same engines ran better because the automobile industry wasn't perfect. Thank you Powernation for opening some people eyes.. But most us knew that 305 was in the 265 family.

I love it! I really like having a motor that revs out. They sound so good and I think are just more fun to drive.
Always loved the 305 my first engine I ever built.
I have two 305 engines with mod cams and headers that run great. 350 where hard to find and people practically gave me the 305 motors. I love 'em. I never wanted more power and my 40 chevy has been on the road since 1996 with no trouble, no over heating and enough power to spin the tires on the 1-2 shift.
That's a pretty spicy 305! Now imagine this engine with a medium-size turbo, and a milder valvetrain.

@luckyPiston My in-house lead man worked with team force for 15 years he is a wiz at wringing out every ounce of horse power possible out of a motor. We're working on doing a full video build of a 335 stroker/ blown hitting 600 horse.
How much do you charge to rebuild the 305 your way?
The 96 and up Vortec 305s are a fantastic engine. I dropped one in my 86 GMC after i messed up the 350. The 305 was free, so i figured it would be good till I fixed the 350. That was 10 years ago, lol. I used a edelbrock performer knockoff intake and the original Qjet. Headers and 2 1/2" dual exhaust woke it up.
I have yet to see you guys run a 327. Start off with the best heads (double hump) from back in the day (maybe ported and a good port matched intake) put flat tops in that makes about 10 to 1 with a dutnov grind 30/30 cam and a 650 carb. Then build it again with a lighter forged rotating assembly with lighter rods and pistons and good hardware. 11.5 to 1 compression is completely doable with aluminum pistons and heads with mls gaskets. Stick a healthy sollid roller cam to make power to about 7500-7800 rpms. Get a good set of AFR heads and a fully ported and polished edlebrock rpm intake with a carb spacer. Playing with different styles and widths could make good content then try a as cast vic jr then one with just the ports cleaned up both port matched to the AFRs of course. This could be a three part series. 1st Run the first engine with 91. 2nd the new combo and fully ported rpm air gap and different spacers with 91+race gas octane booster. 3rd with the vic jr as cast 91+ booster and then ported with race gas. It would just be cool and very interesting and enlightening to see/compare the difference hp/trq numbers to give people an idea where they could potentially save a lot of money and still make good numbers or if its worth spending just a couple hundred bucks and make awesome power. You guys do too much LS stuff and dont get me started on how many different small and big block Ford combos you've done.. By far and away the 327 has been snubbed by powernation for more than a decade! Time to show this forgotten gem some well deserved attention! I mean you guys have litteraly done 283 350s maybe 377 383s 400 and 400+ cubic in small block chevys but never a 327 to my knowledge.

Engine Power is my favourite channel I love all of the engine builds.
Really they are mainly seen being used in certain stock car racing classes. I have seen them at the shop with splayed caps and built up pretty powerful running high rpms and living just as long as the 350 engine. Interesting video for sure but I am a big block chevy/ford guy for life 😂
The BBF/BBC are no joke, but lil engines do hurt big block engine's feelings at times.. i too am a big block guy myself, can't beat the raw power they make in n/a form..
Proof that with enough money, any engine will make power. I've never had a problem with the 305. Just a good, durable engine that was strangled to meet emissions
Nicely done gentlemen!!
If you have a 305 in your own car this series makes a TON of sense to me. The 305 was around during the decades when fuel economy was being strictly mandated for the first time and there were no quick answers, so people talk about it like the engine sucks. There's nothing wrong with 5L of displacement if you just let it breathe.

You are the dream guy that I would love to have honing the block of my 383 build. I had to settle for a local machine shop, so wrenches crossed she is straight.
Cool video but i would have liked to see the stroker with the same heads/cam as the first build so we could compare stroker vs non stroker power directly
I can already tell you what would happen. It would lose horsepower and gain torque, which in this case would probably be a good thing, being it's going to go into someone's street beater.
The first version would be a nice budget. Friendly wake up for a 305.
This episode is 30 years too late. 😂😂😂
Not really ppl still running the 305
I’ve got a 305 in my car so I’m seeing how this turns out and see if it’s a better idea than buying a different motor
I mean not really, I still have four 305s in my shop. I'm sure there's plenty of other people that do also.
@@NOWB504 Have you tried to buy a rebuild kit for a 305 recently? 😮
they all our are lol
My 78 Nova has a 305 and I have had it rebuilt and runs amazing!!
Really good stuf , but you can prove a lot of things with money!
8:53 weld a flat finder washer first and then the nut trust me .
I guess if u have an unlimited budget...
An amazing machining job with this block!
Pretty damn pointless to build a 3.75 stroke 305 instead of a 350
factory motor class? (I'm not a drag nerd but I've heard of something like that before. I'm probably wrong tho) completely agree tho
Well that's your opinion,, and like ARMPITS EVERYONE HAS ONE AND MOST OF THEM STINK😮😂😂😂😂😮
That's your opinion. Keep it to yourself.
Anyone on planet earth can find a hyd roller 350 core motor for $500. Why would anyone in their right mind spend massive $$ to stroke a 305, then be stuck with small-bore heads?
@@JS-kd7jf No, this isn't opinion. Compare a 3.75 stroke 305 to a stock 350. The 305 based engine will require heads that cost more and flow less because of the small bore
I could get you alot more out of your combos, but enjoy just watching what others do.
Good Job
👍
My Dad replaced the 4.3 V6 out of his '88 Chevy Cheyenne with a 305 from a '79 El'Camino, which came with the transmission also. That truck would still be around, had he swapped the rear end for a 12 bolt. Or at least changed the diff fluid a time or two....lol. But that 305 really livened that truck up, along with that transmission.
I've always been curious about a 305 build, cool video guys!
I have a 307, with forged pistons, moly rings, windage tray, 2X hump heads, solid lifter fuelie cam, 700 double pumper, etc. 7,000 rpm almost daily. Never let go.
307 before a 305 anytime!
Awesome project!! Grew up with these being a boat anchor.
Do own one on propane sitting in an old school bus. Itching to pull it and make it more efficient.
But to see parts off a counter make over 500 horsepower is great.
Great job, hope to see a chevy 302 come up
I am a guy born in the early 70's and teenage muscle car, gear head days were the 80's. I can tell you my older gear head cousins always said they were throw away engines and not worth doing anything with. I did always find it funny that the holy grail small block chevy was a 302 and everybody ragged on the 305. Anyways, its nice to see that the 305 is not a throw away and it can make some really good numbers!!
