- We built a "327" SBC the hard way by combining a 283 crankshaft and a 400 block. Our 329 SBC's first dyno session revealing valve float. Engine specs listed below. View our 329's second dyno session: • Dyno #2 283 Crankshaft...
This dyno test took place at Richmond Engines for our 329 cu.in. SBC dyno test, with the best dyno pulls reading 500.3 HP and 427.2 LBS FT. We did notice valve spring float and addressed it here:
• 283 Crank + 400 Block ...
(Why "destroke" a SBC, use a camshaft with conservative intake and exhaust duration, lift, and lobe separation angle? Because we can. And we did-producing fantastic horsepower and torque numbers that would suit any street application. )
The 87 octane dyno tests had a Holley 750. The 94 octane dyno tests had the 750, a Holley 830, and a Holley 770-the final pulls with the 770 were not captured on video, and our 329 accomplished 498.7 HP @ 7,000 RPM (second dyno session 512.1HP) 417.1 LBS FT @ 5,600 RPM (second dyno session 435.7 LBS FT), still exceeding our expectations, with approximately 35º timing. A Performance World HEI distributor was used for this test. The 329 had ample time for warm-up, break-in, and was solid throughout the entire session on the dyno at Richmond engines. Valve float was noted above 6800 RPM. Did it limit this engine's potential? See Part 5 for the component upgrade and Part 6 for the re-test!
Richmond Engines balanced our rotating assembly. It's as smooth and sharp as a scalpel! A huge thank you to the team there!
Michael Shumey, of Canada Engines, meticulously prepared and assembled the 329 short block. Thank you, Michael!
Because cam and engine specs have been requested:
Cam
The lobes are from Comp Cam's Extreme Energy family and are numbers 3314 and 3315.
It’s 224/230 @ .050” lift. With 1.6 rockers our lift is .536/.544 at the valve. Our cam has a 4/7 swap, with the final cylinder firing order being 1-8-7-3-6-5-4-2.

Back in 1995 I had a de-stroked 400- which made it 377 cubic inches, it was a monster! It was in my 1970 Monte Carlo with a m21 4-speed with 390 gears in a 12 bolt position, i shifted at 6800, ran 11.12's weighing 4200 pounds
Sounds awesome! I just love those Monte Carlos too.
Nobody does that today. It's all turbos and the bottle. Good job.
Thank you for commenting :)
Do you remember the specs of the heads and cam and compression?, That's a great time for the gears and weight 💪
Thats hella cool, my iron headed 350 powered 72 Monte Carlo weighs 3,770lbs with AC and rally wheels on a 12 bolt... wonder why yours weighed so much more. Mine ran a 15.5 bone stock.
Kinda nostalgic...
We built so many oddball engine combinations decades ago, making our own main bearing spacers, sleeving blocks for bigger bore sizes, big breathing heads came from hours of hand work, parts swapping from brand to brand etc etc, back when stroker cranks were welded and cut and high strength fasteners came from either tool & die or the aircraft industries.
Everything old is new again.
Very cool! Thanks for commenting!

You're plenty welcome!
There's so many area's of engine building to be revisited because of advancement in other areas, airflow potentials unheard of except in the 'secret rooms' of the top Pro/Stock engine builders (Bob Glidden has never really gotten the recognition deserved for his cylinder head developments, not just with the Cleveland Ford), camshaft profiles once thought impossible, spark curves only now possible with electronic ignition management etc, now available over the counter, making new combinations working with "old" areas completely worth investigating.
I NEVER restricted my business or research to any one engine brand, there's so much to be learned from one design to the next that moving my knowledge forward meant WAY more, and I preferred the challenge.
One of my personal toys - I was in the business for just over a decade and still would be if not for financial damage done from divorce - was a 2.87" stroke x 4.15" bore 8.2 deck SBF with very heavily modified early 351W heads (the Tool & Die background of my family allowed modifying blocks etc for very little to no money) and a G.K. camshaft of my own specs.
Very long story short, just over 520fwhp at 7900 on 89 octane pump gas, acceptable street manners even carbureted, and a notoriously fast little street racer still able to be driven back and forth to the shop.
The short strokes allow for some big rpm (low mean piston speeds), I still spend time investigating rod length to stroke ratios as well as bore to stroke ratios and the affects they have on power under the curve and shape of the curve, valid when building to suit a specific car's intended use.
I found there's a lot to be gained by working the area between max torque and max horsepower just through different bottom end geometry - so thanks for visiting this area!
Mike, thank you again. Very cool project there with your SBF.
I really appreciate your enthusiasm for different engine combos!
What was your favorite sbc combo from back in the day?
@@SketchysGarage
I always loved a high compression 327 with a wild solid roller camshaft and a single plane manifold.
Now I’m building several different things like these short stroke combos as well as long and short stroke LS motors.
Always something a bit different.
Same exact engine setup my late uncle ran in his dirt track cars! He’d turn them 7,200-7,400 rpm with no issues. They love to rev out! His was also making around that 500 HP mark. He had a lot of wins.
That’s awesome! Thanks so commenting.
Many moons ago back in high school,I built a 327 small journal 283 crank and dome pistons ported 202 heads never got beat! The sound of it 7000 rpm I'll never forget
That awesome!! Fun times I bet! Thanks for commenting :)
Roy Huff ,
The small block 307 is a 327 crank and a 283 block
The small block DZ 302 is a 283 crank and a 327 block
I have all of these cranks and all of these blocks
One of my 327 engines is in a 66 Chevelle Super Sport , 12 :1 Forged pistons and Steel Vette crank ,
11 inch clutch , M-21 Muncie 4 speed , 12 bolt posi rear end ,
Pulls both front tires off the ground,
Revs to the moon at 11,000rpm !
450hp
Sounds like fun!!
@@jimthomas1989 what rods for the 283 crank in 327 block.My friend had 307 crank in 327 bored supposed to been 335 I think
@@badassbees3680 , I think 307 uses 5.7 Rod and I'm not sure if it is 5.7 or 6 inch Rods for the DZ 302 but it's a 283 crank , I will have to check on it
Awesome! My 327 made that, spent a small fortune but it was a giant killer!
Your 329 is a killer but a different cam and springs you would run over 7000 rpm and 500 hp with huge torque numbers!
Man I love this build!!
Thank you for commenting! Look out for another video in a week or so. We just added some spring pressure and titanium retainers and we’re going to whip it again.
Agreed, that LSA needs to be narrower.
We’re happy with these results for the application we have.
Next build will tighten the LSA and get more out of the top end! Thanks for commenting.
Vice Grip Garage approval.
Makes me wish I still had my '67 302. That sound at high rpms and the realization of what a shorter stroked engine can accomplish, gotta love it.
We appreciate your comment, wfd805!
Don’t think there was a 67 chev 302 !
@@edwardhuett7924 there was, indeed. Small journal. We have a guy here that has his all original 67 Z-28 and the factory 302 is still in it.
@@wfd805 thought it started in 68
@@edwardhuett7924 no, in 67. It was for the Trans AM race. They were limited to 5 liter engines and that was the answer. They had Zora Duntov work his magic and the 302 was the outcome. I know there is a lot of mystery around the reality of the 302 chevy engine and most parts suppliers don't even acknowledge it ever existed. But, they did and are gaining popularity in collectors again. I knew mine was original also. My friend Gary bought the car new in early 67 and he pulled the engine to drag race a big block. When he passed, I was lucky enough to receive it. But, I got bit by the big block bug. I sold it to a police officer for his 56 chevy.
Ran similar motor combo about 30yrs ago in a class rule deal, max 320cu, OEM production block, crank and rods only & cast iron heads, it used a 400 block, 265 crank, chrysler 6.123 rods, 14:1 made just over 600hp @8400 on alcohol in circle track application, it's a sound combo
I'd been waiting for someone to bring up some rule restricted circle track combinations.
There's a lot of it that applies so much better to street/weekend race cars than the specific drag race build mindset.
Thank you.
@@Motor-City-Mike going smaller bore larger stroke is not worth anything if your not running down low enough rpm to make use of it, the improvement using 4.125 bore to cylinder head flow back then was huge as you could lay the chamber walls back so much more and using a 4.125 dome piston gave a lot more dome volume to bump compression, we ran a street version some years later using dome piston and increasing combustion chamber size as we found the dome slowed the flame travel enough to run a high compression ( for street) 12.5::1 without detonation, relieving the quench pad area to a slope proved best as unless the quench clearance was virtually zero it seemed to do very little to prevent detonation ( broke a few motors finding that one out)
I bet that thing sounded INSANE
I seen some serious small block chevy power back in the 70's and early 80's when these engines were everywhere. nice build!
Thank you for your comments!!
Beautiful build, and it sounds GLORIOUS! 500 HP on pump gas with a 3" stroke? That is a GREAT accomplishment. Thanks for sharing this gem!
Thank you, Greg Plant! It does sound glorious!
Not really. With a short stroke, spin it fast enough the numbers go up.
Remember, this is break-in. Thanks for commenting.
My first racing engine used a 307 block. Mainly because it was free but also because I was just getting started in an IMCA modified and needed seat time with a lower power motor to save money. I was definitely budget constrained. My engine builder was an old timer who knew how to make engines that lasted. I could certainly run with the pack and because I had been setting up modifieds for other drivers I knew how to get through the corners and get all my horsepower to the ground. There were a couple of guys running 406s with tons of hp burning up two tires every night. Difficult to compete with that but that 307 was what I needed to get started.
You had a 283 block. Same thing
This is one of those reasons I really love GM for classic Cars and hot rodding. It's like a Lego set. So many parts fit together in different combinations, and making a fever dream engine work, is a lot less difficult than custom fabricating everything. It gives those of us, like you, that are incredibly creative, the means to really test out every wacky combination you can think of.
I love that! Thanks for your comments :)
Great job guys!
Big power out of a little guy!!! Some more cam R&D and better valve springs that little motor should be fun!!!!
Sounds great! Love to see what it could do with more valve spring and cam.
Thanks for the message! We plan on running it up again after making a small change. Watch for another video to come!
That is so freakin cool..My first 56 chev had a 283 in it...all 180 hp in 1970...:) You guys are giving me ideas!
Hey, thanks for checking us out!
I hope you’re motivated to build something unique too :)
Awesome little motor, sounds like valves floating on top. More heads cam and intake and would be a serious contender such a small displacement.
Hi Rick Lauster! Agreed. It's all in the R&D! Best regards!
Would love to see a solid roller cam
Ya know, that is a great thought. Typically I’d build something like this with a solid roller but on this one we utilized a set of good used hydraulics because we had ‘em.
Thanks for commenting :)
Great idea. Destroking the engine, just like Chevy did with the 327 to create the 302 to make power.
Hi w41duvernay! Thank you for commenting! We think of it as applying tried and true principles. There's something surely going on with a longer connecting rod that's benefitting power, torque, and efficiency; it's certainly applying the characteristics of what a short stroke produces, (and we are learning those characteristics as we go). Best regards.
If i remember right, a 327 block , a 283 forged crank, and a 5.7 rod , did reproduce the 302 z28 engine. Won't be a DZ block, but ....

That’s correct!

Awesome what you guys built

can't wait to see it on the street
You guys cut to the chase, unlike some, I like that. Thanks for the post. I'm building a 301 just because, lol. I picked up on your selection of rod length as well.

Sweet :)
So cool, ever since I had a small block 400 in my first car in 1986 I wanted to build this combo. It would be so fun in a lightweight build
Hi XOZ Industries! Thank you for your comments! Here's our 329 SBC, installed in a 1966 Beaumont, an A-body, and it's super fantastic to drive!: ua-cam.com/video/QDYyRbgEtxA/v-deo.html
Thanks for the video.😎
Cool. Thank you!
Pretty cool build I’ve imagined this combo in my head thousands of time would love to see this combo with a little more camshaft valve spring and single plane intake
Hey, thanks for commenting!
It would definitely be nice to build another one and make it a bit more aggressive :)
For this one, we’re so pleased with the results. It’s in the Beaumont now and it’s a bunch of fun. Amazing with the great drivability, mild mannered camshaft and a sweet long power band. The 5 speed TKX is a real treat too!
👍great build! Thats pretty impressive.
Thank you! It a fun machine now. 1966 Canadian Beaumont 2 door post. TKX 5 speed too :)
A super cool chevy small block combo.
Was building them in the 80’s with hi compression, ported Holley street dominator intake, ported and gas relieved Fulie heads and ported quadrajets with inline carter vain pumps (for use when in it) and didn’t have anything running us down. Did run heavy springs and drilled the valve retainers to lighten them up.⚡️🏎
Cool stuff :)
Thanks for commenting!
Very impressive. 500 horsepower and 329 cubic inches of a generation 1 small block. Not bad!
500 or more wasn't unheard of back when a fully developed Chevrolet iron head 331" 327 was a hot SBC, like in the early 1970s.
Ref. some of Bill Jenkins (amongst others) work.
@@Motor-City-Mike Yeah, but with a mild 224 duration cam?
I had me a 283 4 speed 66 SS (originally a 396)Chevelle back in the eighties with a solid cam, single plane, roller rockers etc. that would scream past 8k. The Lakewood scatter shield was a must when the diaphragm clutch would over center and explode. Fun times!
That’s so true! Those fun times sound like my youth too :)
Reminds me of the old small journal 327 based builds the dirt track boys use to run in the 70' into the early 80's turning ungodly rpms.
They'd have headers glowing red after every heat race.
Ya'll remember those days, because I know a couple of ya'll have to be as old as I am from reading comments.
I never did sell any of em my lil 327 either, and they were always offering me good money for it too.
That's when the engineering was what you could afford, and you used what you could scrounge up between the scrape yards, and friends of friends.
Few had the factory hot rods, but they were usually older just home from Vietnam, are daddy's money.
But most of us just making minimum wages, either still dating or just married back then.
Drinking few cold ones, maybe Mexican cigarette or two here n there.
Mainly it was all about that we could do with our imaginations, the big 3, and WOT!
Who else was like that back in the days of long gas lines, and out running the local police, because you couldn't afford another ticket.
At least that's how it was for me, but couple friends.
Thanks for the memories of times when life was good n simple.
Sounds like some good old fun!! Thanks for commenting!
Now we live in a goddam police state and me and every other 20yr old in America gets given a 500$ ticket every other month from some fat bastard in a new charger or mustang

Not to knock you chevy guys (because I own a '66 Belair 350 now) but Mopar did this with their 340. 4.04" bore x 3.310" stroke. Those factory 7.534" rods was where I believe the magic happened. I had one in my '72 Duster. Was .030 over with X-heads 2.02 intake valves & 292/509 lift hydrolic cam, 750 double pumper and 10:1 compression. I'd wind the shit out of her all day and shift @ 7200 with still more to go. Being a teen on a budget I'd run 89 on my drive to school & back if $ was tight. My '66 tops at around 5k max and can't hold a candle to the fun factor of that fast rev high rpm power the "smaller" Mopar offers. It could barely spin the wide micky tires with 355s but 2800/3200 stall converter, it would jump off the line in the power band with full traction & blow the doors off all the 350s with even more top end and power. I miss that car. My research into building a similar big bore short stroke Chevy for the '66 is what led me here!! I still remember the Infamous Hot Rod? Article on the 400 block/327 crank build running on 87 and I always could relate. Nobody believed me I was running 87/89 octane with 10:1 compression and spinning to 7200 being safe. I could shift at 8k without even trying she just wouldn't stop pulling. Though I did pony up the extra cents for the 92 almost always. Back then the cheap stuff could be had for under a buck a gallon..those were the days!
Hey thanks for commenting! I encourage you to check out our other videos where you’ll find our 400 block, 327 Crankshaft build( like the Hot Rod article ).
The long rod, short stroke stuff is definitely the ticket and fun to drive :)
I love this build
Thank you! It’s been so sweet as a street cruiser. Such a fun ride with a 5 speed :)
This seems to prove what Smokey Yunick always argued: “put the longest damn rod I the engine that you can”. Longer rods increase dwell time around TDC and make the heads act as if they were larger than they are. That is why you can get that kind of power with a relatively conservative cam.
Absolutely! It’s so often over looked. Thanks for commenting!
Short stroke big bore is why it rpms like it does. A basic 327 winds the same with mild cam timing.
Dwell at TDC is what results in increases cylinder filling for a given head and cam. That is what makes power.

I am putting together a 353 Cu. In. SBC. A 0.030" over 400 with a 327 crank, Icon forged flat tops, 6.0" rods, Milodon gear drive, Offenhauser crossram and either an 850 or two 600s as I have both dual and single top for the intake. Not exactly sure of what cam I will be running. Initially I purchased the optional off-road Z cam (140) and thinking a solid roller would be fun. RPM will be over 7000 or close to 8000 with a roller. Lots of block prep, oil considerations, and some good flowing heads. I have been dreaming of using the 400 with a short stroke since space saver bearings first came out. I have a set of the Clevite bearings and also a set of King bearing spacers. Finnally I am going to realize my dream engine. Quite a few more goodies are in the engine for reliability, such as Milodon 4 bolt caps, Shark oil pump, Milodon oil pan, electric water pump, shaft roller rockers and so on.
Wow that all sounds amazing. I’d go for the solid roller like you said! And I’d recommend AFR heads. Depending on how much you you go with would determine the size. How much power are you aiming for?
Thanks for sharing your thoughts and commenting!
Tony Mamo flat out got that design right on the eliminators before he parted ways with AFR...
Those heads prove with tests like this what they are capable of... I mean a 180cc runner making 500hp, that is tough!!
Velocity monster ports is what they are!!! It also proves a 300CI engine can make good 500hp power and no need for 383+ unless you want torque.. Look at the ZZ430 430HP on the 350CI chevy.. The LT4 Hotcam is small, 218/228 is not a lot compared to most cams..
With AFR COMP 195's, a Comp 230/236 HYD Roller 350CI on 93 should be thumping 500+ HP all day long with good torque. The stroke is the issue for torque, on the street torque is key..
Nice build...
Thank you very much for your comments! We’re very happy with the results except not quite enough spring pressure. We’re going to lighten it up with titanium retainers and add 50 lbs more pressure then whip it again!
@@ceperformance Bump it up to the XE282HR-10 cam, 500+ all day long i bet! Maybe 520 from where you left off!

Hi Rick Dion, agreed! We knew we were on to something when a SBF 302 cu.in., with AFR heads and a 9.1:1 c/r, and 6" rods, produced 455 HP and 375 LBS FT-1.5 HP/cu.in. We applied that to this build and achieved the same result and a couple extra-1.52HP/cu.in. We didn't produce a dyno video of it, but here's the SBF 302: ua-cam.com/video/cgzTemIAMvI/v-deo.html.

It because Chevy never built cnc heads to make this combo worth producing on a factory style head this combo might make a horse per cube, but as I said before you can put afr heads on anything over 300 cubes and make 500 hp
They sure do work great!
They might have done something similar if the muscle car era had continued, but the manufacturers were forced into focusing on economy and emissions instead of performance during the 70s. Remember, the 400 was introduced in '70, right before GM's big compression drop in '71.
Absolutely right. Glad we can do these things ourselves :)
I've wanted to do this with an aftermarket Ford 8.2" block. Nice tidy package with short and light rods.
I agree. The SBF packages are really great. We built a “302” a few years ago for a custom who was building an endurance race Old School Mustang he was taking to the Baltic Classic race. Quite an amazing adventure… worth a google search :)
www.endurorally.com/events/the-baltic-classic-rally/
He needed an engine no bigger than 5.0L that could run on crappy fuel and run the distance.
What we built him started with a Dart block with a 9.2” deck height (not the standard 8.2 or the larger 9.5 like the 351 Windsor). We used a 3” stroke steel crankshaft and 6” long Scat rods meant for a Chevrolet. We narrowed the big end to fit the Ford crank journal width and hit the 2:1 rod ratio. With a very mild hydraulic roller and 165cc AFR heads it made 450hp between 6500-7000 rpm and a broad torque curve peaking at 5500 rpm (375 lbs).

I've been looking for a video on this engine combo, I've wanted to build one of these for the past 20 years. It's too bad I'm just now seeing it because it would be really awesome if you keep improving the weak links and got her to really zing! 👍
Hi Jed! We certainly agree! And that can be applied to any project. However, there comes that inevitable time when the artist must step away from his painting. Imagine this: ua-cam.com/video/xv251lDtGu0/v-deo.html . Thanks for commenting! And, if you want to build an engine, get in touch with us! ceperformance.ca
I have been wantiing to build this myself, and I am glad someboy did. I love the big bore short stroke long rod combo. Be interesting to see what it would do with big exotic haeds, and/or a Smokey Ram Intake. How about some 450 CFMer heads. RPM screamer. Awesome.
Thanks for commenting. Absolutely, it would be great to start again and change things a bit on the next one. This engine just sold so there’s money to spend again!
I really like that little engine although I don’t like the idea of spacer main bearings but it’s mainly because I don’t know anything about what your using exactly & if it’s a big weak spot or not.great job man 👍🏼
Thank you for your comment!
Race Engineering takes an HP King Performance main bearing for a 400 and trim the inside to fit the 350 bearing inside of it. It’s an absolutely perfect fit and we have zero concerns with using them.
Give and take. Not sure anything is needed 500 hp and will turn 7000. Very respectable. Sounds like it will live a long time. Nice
Take a bow, well-done
Thank you sir!
All 265s and early 283s had factory steel cranks . Took my 301 to 8 grand a hundred times at Lions drag strip and the others . Never had a crank/rod fail 👍 Neil
Awesome :)
Looks good for my daughter's z28.
1.52 Hp/in³ Well done guys !
Thank you! For such a mild mannered motor, we’re very happy with the results.
Have a look at this build…

Bigger Caleb got you over the hump. 👍🤓
We appreciate the viewership and inquiries. Check out our previous crate engine build based on "The 350 that Chevy should have built" article, a 400 block with a 327 crankshaft, using 6.250" connecting rods instead of the 6.209" connecting rods that the article covered. The SBC block we used was a salvaged Dart block, a block that had been damaged during a race-track incident, with 350 (2.45") mains: ua-cam.com/video/3oLz362AbDU/v-deo.html
What compression ratio was this 329 ?
@@jimthomas1989
Thanks for watching. It’s 10.78:1
There used to be a shop just off Scott Rd. that specialized in rebuilding Chevy small block engines. I was into off-roading, not street racing so low end torque was more important to me. I had a small block 400 in a Blazer that they completely redid and turned it into a torquey stump-puller which I also used for snow ploughing. Previous to that I owned a1963 Chev 4X4 Panel truck that I found in Burnaby with an actual L76 in it! At one time or another I've probably owned every Mouse engine made,
Cool stuff! Nice to hear that your from our area :) Thanks for commenting.
That suckered is SMOOTH!
Thanks! It has great drivability and still boots very well :)
Sounds great through 2.5” pipes.
that was so cool. i am building a Dart block large journal 327. i thought about going with a 348, 3.25 stroke 4.125 bore and if i had known to get pistons made in north america i had to order diamond pistons i would have done it. hopeing for 440 HP 8000 rpm solid roller daily driver.
Holy moly, sounds awesome. Would love to hear from you when your done!
This would make an awesome engine for a road course car!
Absolutely. It’s pretty fun on the street too :)
WOW very impressive! Thought for sure you lads were going to add a little timing in her on the 87 fuel. What compression is that little beast running please? Thanks and Merry Christmas and cheers from Motown.
Hello Robert and thank you for commenting! The compression on the 329 is 10.78:1
Going to run it again this week and another test video will follow. We swapped out the steel retainers for titanium.
this combo is perfect for pound per cubic inch nostalgia classes... you should market this combo to Southeasr Gasser association
Thanks for commenting! And thank you for that suggestion :)
The sound of that engine is just music to my ears.
Hey, thank you for commenting!
I knew an old dirt track engine builder/driver he made 2in spacers to extend the cylinders deck height with 8in rods it really liked the upper rpm range
That’s hilarious. I’d love to see the that!
Wow! Intake manifold would be something to see on that one!@@ceperformance
@johnadams8975
I would love to build another copy of this with a much wilder camshaft and a Super Victor manifold and take it to 9K.
Thanks for commenting :)
Holy small blocks. That's impressive!!!
Hi arodderz! We agree! Thank you for commenting. Best regards.
Amazing u got that much torque from a 283 crank
Thanks for your comment!
A big part of the success is undoubtedly the 6.1” connecting rods on the 3” crankshaft.
I built a 327, several years ago.. it was a 210 hp 2 brl 327 that came in my 68 Camaro.. Once Worn Out, with little compression, I had an Older Friend, my Dads age, who Drag Raced, in the H/S Class.. He miked out the engine, all componants, and told me how much metal to have removed, from heads, and block deck.. I put in a 3O/30 solid lifter cam in, and my friend, Charlie, the master mechanic, degreed it in for me.. I had a 4-Speed, and what ever gear came in the car.. After about 50 miles of break-in time, I decided to TURN IT LOOSE! I CAM OUT OF THE HOLE, FROM FROM SITTING STILL.. Power Shifting from first, to second, THE SPEED-O NEEDLE, WAS ON 75 MPH, AS SOON As I slammed 2nd gear, and looked.. It was a bad machine!! Once I put in a 57 Pontiac. Rear, with posi, and 5'38 gears, it was TERRIBLE! NEEDLESS TO SAY: I did not make long trips! I did go out 25 miles a few times, at 35-40 mph..
Great old memories for sure!!
I've heard of the Famous Homemade 302 (327 block+ 283 crank) the same using a 350 block (using similar bearing adapters), a 377 (400 Block+ 350 crank) 383 (350block + 400 crank) and even a 334 (I think) (307 block+ 400 crank). This is the first I've ever heard of someone, trying to use a 283 crank in a 400, very cool. Me personally due to the size differences in journals, I might have had a crank custom made to a 400 journal size just for bearing stability, those bearing adapters are notorious for spinning. But this is pretty cool
Thank you! Our block is a BowTie block that has 350 mains. There are still spacers in there to fit the small journal crankshaft but the ones we’ve used fit amazingly and there’s no concern of them spinning. Thanks for commenting :)
@@ceperformance, Ok less adapting is always better, did not know that about the bowtie block. BTW this is still not the most unusual engine I've ever seen. Our local speed shop owner did oval racing and built an interesting stroker small block dodge, He took a 340 block and a 360 crank (turned to the 318/340 main journal size) and offset ground the rod journals to a 350 chevy journal size and used a 5.7inch rod with the stock 340 pistons ( want to say it was around a 370 cu in afterwards). The offset he ground into the crank meant no changes to pin height. That was a crazy fast oval car when I saw it run
That’s some great innovation! Very interesting :)
@@ceperformance, It was a local track class that required a mostly factory engine, but factory was a bit loose, as in other makes and differelt class parts can be used (Example cleveland heads on SBF's or BBC rockers on a small block Chevy) so long as they are factory part numbers, a lot of outside the box thinking there. Hipo Ok, but no aftermarket pieces. I didn't see the logic of shortening the rods, till he explained the class. he was racing more than a few homemade cleveland headed SBF's in that class and held his own. it was a crazy class
It’s great to see that type of creativity come together.
Wonder if an aftermarket Motown 454 ABC with a 262 sbc crank would rev more? And make good hp ?
Did you even try a tighter Lsa, this combo has much more potential than you guys have found !
You’re right about its potential. We were not at all looking for maximum horsepower obviously. If we were then a completely different camshaft, larger heads and a better intake manifold would have been used. What we’re impressed by and happy with is that even with very conservative components, the output and drivability is remarkable.
Thanks for commenting!
Holy smoke! That one shot showing the top of a piston in the bore looked like you had at least a .025" piston to bore clearance. Expecting some serious heat were you?
The clearance is.0025”. I think your eyes are fooling you.
I could do that stuff all day long.
Couldn't afford to go to school for this stuff , had to go to work in construction.
First time to channel , impressive. Canadian , eh ?
Thank you! Yep, Canadian!
we put in a 235 custom made crank in a 327 then ran aluminum titanium alloy rods that then put in over sized cylinder in the block, we even seasoned the block polished the inside of block ported everything. the crank was built for the rods and piston we used matched the counter weights on the crank . we had to port the cam bearings to get the custom cam in it just to big for the stock bearings. but ended up to be one crazy engine even terry fisher said it was crazy when he drove the car. we started with rick news dragster engine then ended up putting another 25,000 in it . we went with high compression for a tunnel ram 13.5 to 1 it came out good, runs rpms like most engines dream about. the pro racing engine builder said it would run 10,500 rpms all day long. i have had up to 15,000 when my clutch blew but then i got a rev eliminator i try to shift at 9,000 rpms. the engine still runs today it has lots of runs under its belt but i try not to push it to its limits it just cost to much to repair it. every time i had to tare it down it cost 5,000
Wow, sounds like a beast :)
@@ceperformance the most expensive engine i ever owned but been getting lucky getting the 4 inch stroke 454 with the 02xx 400r turbo trans for free with low miles on them got 4 so far from 6,000 miles to 58.000 miles on them modeled after the ho 454 70 chevelle engine 450 hp at 485 torque stock crate combo trans good to 800 hp
Sweet! I always thought about building this combo. I even sent it to HotRod magazine years ago hoping they would build it for a engine contest that they had.
Interesting! Did you get a response?
Thanks for commenting :)
@@ceperformance Unfortunately no, I think they ended up building a Chrysler engine. Thanks.
Oh well. Good for you to reach out to them anyway.
Maybe not to late to build your own project!
I’m building one now 400 block 4.185 bore 3.50 stroke crank Honda rod journal size 220 afr heads 12-1 icon 2618 pistons all arp studded and strapped main caps 4 bolt main not the 2 bolt come out to be a 383 cubic inch that will turn 8200 all day long estimate realm of 650 Hp with around 550-575 ft lbs of torque but we will see after it’s built havent decided on cam yet but will be around 270 at 50 should be real fun with a m22 in a 78 Camaro
@@thomasbradley7844 Tom, that sounds real cool. I have a mild 383 in a 73 Vega. I hope to have it on the road soon. I don't think that Muncie will last even if it's a m,22. Good luck.
I saw this done back in the 80s.
Back years ago Hot Rod magazine did a engine design competition for its readers. The design I entered was a 400 with 3.0" crank. Didn't win of course. I never had the funds to build one and always wondered how it would work. It is cool to see you guys building one now. It would sure be fun in my 1989 iroc camaro. Or my protour 1969 camaro. If I could get specs on bearings / proper rod length and piston pin location for thus combo maybe I could build one.
Right on! If it’s a possibility I’d say go for it :) This would be great in either one of those cars.
Make your dream a reality! Thanks for commenting.
An 8000 RPM supercharged version would be an absolute blast!
Ya that would be amazing :)
Thanks for commenting!
Great vid. I wonder how much this combo resembles the Z/28 302 specs?
Hi Giving! Thanks for your comment! There really isn't a comparison apart from the 3" stroke length. Here's another channel's dyno test of a DZ302, producing 415HP and 345LBS FT: ua-cam.com/video/i9vJ5BYhje8/v-deo.html , and the top comment read: hot rod magazine or super Chevy magazine did a build with the dz 302. stock block, ported 186 heads and crankshaft. aftermarket pistons, rods, cam, headers and intake. it made 501 hp @ 8500 rpm. pretty impressive.
Our 329's second dyno test resulted in 512HP and 435LBS FT, a result that surprised us and that we are very happy with: ua-cam.com/video/Ge6RsIOs1-U/v-deo.html
Considering the short stroke and mild cam making that number without rediculous rpm is impressive!
It will never wear out thats for sure!!
Internet says you cant make more than 350hp without a turbo ls. Gen 1 forever!
Right on! Thanks for commenting :)
I’ve put together a couple of 364 inch combos by having the crank offset ground to run 327 small journal rods and they always worked well.
I’m currently screwing together a forged bottom end 355 with some 205cc intake runner aluminum heads that is to be a 500 hp base for a 200 shot of spray.
Just found your channel and will definitely be looking at more of your videos.
Thank you for commenting! What rod length went into the 364 combos?
@@ceperformance standard 5.7”
The 350 block is bored .030"over, and the standard 350 crank is offset ground 1/16" , with the rod journals turned down to the old 'small journal' 327 size.
If you use an aluminum rod you may have to clearance the block on the pan rail.
Much easier on the ears than the 6200 I used to shift my factory '70 2-bolt 3951511 block 400 at. She is moth-balled for now but I am starting to see a 283 and crank in her future!!
Go for it!! Thanks for commenting :)
We do very much the same combination with slightly longer rods more compression little bit more cam he was making 600 hp it's there you just have to talk to her
