Building a 480hp Classic 383" Small Block Chevy - Smeding Performance

[@AutoAuctionRebuilds]

Thank you for an amazing engine! It just arrived today so the Monte Carlo SS is about to be torn down! EPIC video!!

[@6.0999]

Thank you for hooking up auto auction rebuild with phenomenal 383 stroker!

[@galeng73]

Thanks for hooking up AAR with the sponsorship. That made me visit. I'm actually in the market for a crate engine, as I have a project in mind. I'll definitely consider your products.

[@MartinScreeton]

I'm looking forward to seeing Randy put that into his 1987 Chevy Monte Carlo SS! Very Cool!

[@alexlozano1722]

nice to see everyone wanting to do an ls swap. making the price for a small block chevy more affordable.

[@Seymour5575]

All I can say is WOW so cool thanks for building that sweet engine for Randy.

[@donnysandau1548]

Thank you for working with Randy at Auto Auction Rebuilds on a fantastic engine build. You have yourself another subscriber. Can't wait to check out other videos of yours!

[@VWMANCA]

I THINK U MEANT TO SAY "AUTO AUCTION WALK AROUNDS" THERE AIN'T NO RESTORING OR REBUILDING GOING ON THERE. LOL. Now this channel is a different story..... great things happen here.

[@KylieWalkerT4t]

Thank you for hooking up AAR man we sure appreciate what you do the hard work you put into building those balanced engines!!

Thanks for building the 383 stroker for Randall at Auto Auctions Rebuilds!

[@robertwest3093]

Man that cam lope is perfect. And the engine sounded awesome on the dyno!

[@JosephGuzman-k4k]

I can't wait. I just older my 383 about two weeks ago and should get it in about two months 😁

[@MichaelSmith-cn7se]

Came over to see Randys engine. Looks great!

[@joer8399]

Nice engine, cant wait to see Randy start the Monte Carlo with the new 383. The stock 5.0 v8 is ok, but nowhere near 480 hp.

[@patbullard9276]

I loved the time lapse build. I get all that I need to see without the chatter. Thanks.

[@waverlystevenson426]

Came over from watching Randy’s channel and I’m very impressed. Will definitely be subscribing and keeping you guys in mind when I’m ready for a new build .

[@rinoabate5013]

Great engine build. Thanks for sponsoring Randy at AAR with this engine build. I currently have a project I would like to build and will definitely consider your products.

[@edwardkamenar1493]

Popped on over from Auto Auction Rebuilds to watch. Loved it.

[@hughobrien4139]

Those are some extremely nice upgrades to that block. Two detail items I’d like to know more about. How much lobe lift does that block allow before the oil pressure band comes out of the block? I know there are some lifters with work arounds for this. Just cost associated like in most cases. The other item is cylinder distortion under torque plate honing conditions . Those blind head bolt holes are a plus no doubt and I know that those head bolt holes were CNC machined and much more accurately located than the factory based engines are. When decking these style blocks the head bolt threads being flush with the deck makes it necessary to champher the bolt holes. For this reason it would be very nice if those head bolt holes had a counter bore depth before the threads began. I’m sure it could be done and still accommodate a common length ARP stud. Just think that it would improve overall quality and even help the manufacturing process. Couldn’t add more than a minute to the cycle times. Over all those are major nice upgrades. A 4 1/4” bore ?

[@rosagg1368]

Wow, that cam lope is exciting! Awsome!

[@Dalt634]

Great video for Auto Auction Rebuilds of Randy's engine!!!

[@jeffdohse7124]

All i kept thinking was 'overbuilt for only 480 hp'. Thinking to my 500 hp 500 lb torque 1971 block with 400 crank & hypereutectics Run since 1999 with No problems.

Thanks for building a nice engine for Randy!

Great job with Randy's motor

[@cuzz63]

Glad to see you guys ran a 650cfm carb..so many people over carb the motors.

[@lit549]

Ehh, 750 would be the better choice on that build.

[@cuzz63]

@@lit549 not really since its below the 500hp threshold. 650 will support up to 500hp. I could see that argument if they had thought the motor would go over that and then was restricted or if it wasnt going in a street car/

[@jeffdohse7124]

I ran a 650 on a '500' hp 383 switched to a 750 cfm & the 383 was ALOT happier

[@cuzz63]

@@jeffdohse7124 how much difference in HP and torque?

[@jeffdohse7124]

@@cuzz63 Engine shop used a 750 on their dyno. Never got around to Dyno'ing with my BG Demon 750 but it pulled a lot harder. 13.0 1/4 mile w 650 Edelbrock & 12.6 with the 750 Demon. But I also had pocket ported heads & port matched rpm intake So the better breathing made a difference.

The best way to set valve lash right there 👍

[@thomasfulton5696]

I'm thinking about saving up and buying an older Chevy truck with a 350 want to have it bored over to a 383

[@kelvinhayes4177]

Like how the motor runs and sound. Very good build. I really enjoyed the video. Strong!!

[@allenwind6412]

Awesome I'm torn between 383 and the 406. I had a blueprint sbc 396 in my 71 k10 short bed. Need more power. Lol 510 wasn't enough. 😂

[@travisartis5141]

421 is what you need

[@jeffdohse7124]

Are you going for street manners? For the price of a 600 hp small block drop in a big block and reap the benefits of big torque. Just a thought

[@Chopski64]

I like the water pump spinning on its own. Nice builds. I built mine locally but it cost more for sure.

Amazing Offerings... Thanks for Sharing

[@Yard27955]

Thank you for building, auto action, rebuilds engine

[@chadrivers1568]

Why would you not use a 4032 aluminum forged pistons? Wouldn't that be more suitable for a performance engine? I guess I've seen to many explode in circle track racing and that's very similar to drag and drive out power tour type of situations and heat cycles or loads. Just my opinion nice build either way guys.

[@4x4simon4x4simon]

I like that the sleeves are longer to protect the skirts. What's the cost of this package

[@LifeofShiizard]

Wish someone would make a stroker kit for Oldsmobiles 350,403,455

[@scottm7341]

Long live the SBC! I heard of you today from a friend who just ordered a short block. Very impressive how you are making all your own parts, and it's a good idea to use a 4.000 bore with a 3.8 stroke to get the 383 cubes. What is the make of the HEI dist?

[@joeyjojojr.shabadoo915]

Do you guys also offer a 4.125" bore SBC or just the 4.000" ? In terms of the added material that you mentioned going into the block, is that more or less a substitute to allow all perpendicular main fasteners rather than outside splayed ? How about Billet Main Caps as an upgrade ? Very nice looking block. The cam thrust plate is also a nice addition.

[@christopherhorne8665]

Splayed mains are stronger than straight.

That's correct after the two 429 Cobra jet engines the second one had the oil going to the crankshaft first cause on the first the crank seized.

That is a (SMOKING DEAL) on your "POWER ADDER" shortblock with that block! If i had the coin i would throw it down right now as i planned to build a all forged AFR headed version to replace my GM ZZ430 clone. I do wish you had a normal 350CI.. It would also be cool as crap if you guys did "RETRO" 302CI, 327CI, and 396CI Small blocks as well.... What is the Max HP rating that block of yours can handle? I wanna add 15psi and shoot for 750hp+ /650RWHP... 90% street engine... But i want it to last. And what oil pump do you guys use? Melling "Sharktooth"?!? Those are the one i had planned to get.

Nice driver

[@normbarrows2]

my 30 over 350 makes more power than that. how can you have a 1/4" more stroke and not even make as much power? Obviously, you did something different (perhaps wrong?). Guess I'll have to watch, just to see what's up. Or it may be a case of apples vs oranges - different goals - different results. Compression ratio - I'm running forged pistons at about 10.25 to 1. Valvetrain - True roller here - get those steep cam profiles that really breathe. Heads - I'm running Brodix Track-1's - best breathing 23 degree head I could find - beats airflow, edelbrock, etc. Induction is another difference. I'm running an Offenhauser Individual Runner Intake with twin 390 double pumpers with non-progressive linkage. It's basically an eight one-barrel carbs setup. Nice block, BTW. All I have is a Summit 4 bolt with a Moroso two-piece rear seal adapter, and a two-piece rear seal forged Chevy steel crank. Given the differences between the two builds, everything makes sense. I wonder how they compare on cost. From your website, your stuff seems pretty reasonably priced. Mine is actually a re-build of a 30-year-old hot rod motor. I was able to re-use the crank and cam and had to replace everything else - even things like the distributor and water pump and the twin aluminum big block radiators and 4 cooling fans that keep it streetable.

I'm a bit young, honestly I'm only 13, but im building a race car right now, does anybody have any recommendations on what kinds of parts I should use? I'm starting with a 480hp 383; Specifically this model, any help is appreciated greatly!

[@PapawCulberson]

No soaking the roller lifters in heavy oil before install? No builders grease on push rods or rocker rollers? Let's hope that you run the oil pump and rotate the engine by hand before you fire it up on the Dyno. I suspect lifter and cam failures - am I right or are you doing the things that we didn't see in the video?

[@docsmallblock6584]

I'm fixing to copy a David Vizard 383 build, where they got 620hp on pump gas! I'm going to copy it step by step, part by part. It's here on KZbin if anyone else is interested in building a 600+ horsepower pump gas 383 sbc.

[@lurebenson7722]

I have done one 383 using 6 inch rods and it now is in my 1988 1 ton chev truck so I have started a new engine that is a 385 stroker and again with 6 inch rods for my 1991 1/2 ton chev truck and my gripe is trying to find a roller cam rated at not over starting 1000 RPM or less for a work truck that tows trailers and boats 98% of roller cams seem to be rated for racing application for mid to High range RPM. Look at any 383 video or built for sale 383 SB and they have been done for a race streetcar & race application and no one does a video on a 383 for work trucks that tow trailers. I think I found a comp cam for my truck application but it took 2 months of search the internet and Jegs or Summit racing looking for the roller cam that fit my needs for a cam

[@redlinemontecarloss6573]

If it is a 383, shouldn't it have 4.030 pistons? The ring compressor you used was 4.000. Are you just using the smaller compressor?

They used a 3.800 stroke crankshaft.
