The owner stated it had 10.5:1 compression. You can clearly see the head is marked 75cc, it has a 4 valve relief flat top piston( which on a good day are around a 5cc dish if not more.) You can see the block has not been decked, so I would assume the piston is still 0.025" down in the hole. I can't see the part number on the head gaskets, but by the looks of them they are a fel pro 1003, which is a 4.166 bore 0.041" thick head gasket. That calculates out to roughly 9.35:1.
3970010 350ci 4bolt main was probably one of the best engine blocks ever made between GM cars & trucks, if treated respectably they can last a really long time, mine lasted over 10yrs running hard 400hp and my buddy had a decent tuned one for almost 20yrs. with a cam & timing chain & gear change halfway through, make that a stroker engine with good parts and your getting some torque & horsepower like a bigblock and the higher revs of a smallblock that's a win-win right there.
I hear about a quarter of a billion dollars worth of court orders but damn, What good freakin war music WOW!!!! and threw in the star wars... that was great stuff.... Clicked play again :-)
I change the oil and filter every 5.000 miles so I don't realy care about the filter at all and the variety of US Car spare parts is not very high over here in Germany. I just dont't want to order a just an oil filter from summit if I want to change my oil...thats why, but thanks for the comment!
I usually just close photo montages but your choice of music is quite excellent so I stayed. :-) great looking engine. Was it install error that caused it to blow, or was it a faulty part?
Hi sure this is a fuel sucker, but thats the way it is with high HP Motors! A EFI is way better, more reliable but a LOT more expensive than the 850 Quickfuel which is on the motor right now. I don't need reliability, cause its a saturday night special only driven on the weekend, so I don't wanna spent all that money for something I don't really need!;) Thanks for the comment though! Cheers!
Guys just to inform you...I sold the Air Gap Intake and put a port matched GM Performance 10051102 aluminum high rise single plane with a 1" 4 Hole-Spacer on the Engine.The next step is to trow the Edelbrock shit in the trash an put a 850 Quickfuel Carb on the engine. And this is not a weak hydraulic flat tapped cam in the engine, its a big Mechanical flat tappet comp cam (COMP Cams CL12-678-4). Anything bigger need to be a roller...The engine is now in the 500+ League as planned! Cheers!
Nice motor! good combination of parts. I hope the eddy was just to fire up the engine while the 750 dp holley was on backorder..... I would hate to see the potential of those AFR heads wasted on an edelbroke carb.
Sorry we live on trees here in Germany, we don't have books here! That's why we don't have a clue of everything! Thanks for reminding me! Small hint, much not necessarily helps much! The carb was a transitional solution, it's long gone and the rods a way stronger than you think! H Beams are not the final answer, probably you have to read a book first!?! Schönen Tag noch!
hey man i know how you feel. bought an 88 toyota pickup. 2 months later rod bearing #3 welded itself to the crank, wiped the oil pump, that wiped the head, that wiped the cam, that wiped the rockers. the guy before me replaced the timing chain tentioner and left plastic remains in the oil pan. that clogged the oil pickup. i was doing 98 mph down a hill and then it started slowing down. 1400$ later i have new crank head rockers oil pump bearings gaskets 1 rod.sucks dont it :P
@aminimaleffort u need to build what ever floats your boat !!!! in today's modern technology it is easy to get 650hp on pump gas now and still be cost efficiant and with this technology we able to take a mouse to new levels of hp that was once not capable of doing. for instance my heads i bought last year are old news and now afr has got even better ones to replace mine plus there killer molded 2pc intake to help on cooling. so allready my engine is outdated so build max hp before its outdated
You are right with the compression, it's only 10:1, I asked my friend. That was my mistake but the piston is almost at 0.000" in the hole so he calculated 10:1, he uses probably the same software and stuff you do. He has a real big machine shop over here in Germany and builds american V8 engines for over 25 years now, so I trust him! But you showed very high knowledge in engine building, that is remarkable. Thank you for your comment!
Nice motor. I like 383 and 400 motors. You're right on going with that 850 DP. I had a 750 Holley vacuum secondary on mine with a RPM manifold. I ended up going with a 800 DP and 1" spacer. I run an Isky Z-25 solid cam and 3500 stall, 1 3/4 long tube headers and Pro Topline heads 220cc intake runners. Will boil the tires off my 84 Silverado short box and does a sexy dance in the middle of the road hitting second gear! Thanks for the video. Good job!!
@383TruckRider I'm in the process of building a 388. Was told by Jerry who owns the machine shop that if the piston rings are not file fit properly with the Kieth Blacks that they will expand and rip off the top of the piston. This my first build so any pointers?
looking good, but with carburetor this make a fuel suker: fuel injection is much more efficient and more reliable: see for adaptable injection like Megasquirt...
Nice build good choice in heads. Whats cam profile? Im building a 383 right now and i cant decide what cam to use. I'am using 215cc dart heads with 64cc.
@383TruckRider Oh i know all about AFR heads, we have AFR 195s on an 11:1 388ci with a solid roller cam, it made 499HP ON THE DYNO....... I bet yours is closer to 450ish though, still a good set-up... What cam are you running?
you can have 500+hp with a airgap intake? cause I got a 327 with a RPM airgap and it barely fit(very near) under my stock z28 hood! i want to build a 500hp 406ci and dont want to have a aftermarket cowl hood just to fit a SINGLE plane high rise intake!!
Off topic... Looking at the pistons and the connecting rods: are they miss matched by about 0.100" (too long)? List at end of video says 6.0 rods and 1.22 pistons... if holding 6.0 should be 1.125 pistons... right or wrong? Might be why it blew up...
Good vid, my only beef is going with a cast crank on a stroker, not a good idea. I would have saved the cash on the efi set up and spent it on a forged crank. Lower end failures are the most common problem with stroker builds. And contrary to popular belief MSD is JUNK always go Mallory. Congrats on the build though it looks sa weet!!
u know if you would of got the afr 220s eliminator heads and change cam to a bigger one got a victor jr intake you would be at 653hp also the heads would of cost you the same i got my heads from a guy in tn for $1976.30 with free spring upgrade.
Guys thank you for your opinion. I do know that a 850 might be a little to big for that motor but with my intake, cam and the AFR heads it really performs great! My engine builder also suggested to go with a 850 with this setup, it's a annual booster Carb and the engine makes beautiful vacuum even with the big cam. So everybody is happy! I will have final nummbers on friday, then it will be on the dyno for the final tune.
filler cap to front pcv to rear, keith black pistons in hyper form suck, just plain junk, other than that,nice clean build. on a budget build use the speed pro hypers . thought you might want to know
I love these mouse motors, I put in a mild 260 crane, roller tip rockers and hedmans and imy k15 will break my 33x12.50x15's loose every time. Just a fun almost bullet proof engine to work on. Thanksf or the video...
Ok guys, be honest with me please... I’m pretty much going with the same setup as he did in this video... my questions is this.. CAN I MAKE 450-500 HP to the crank with this setup???? Help me out! Lol
@Mikej1592 Thanks Mike, I appreciate your comment and of course CCR is one of my lifetime favorites!:) The failure was caused by a faulty piston ring, which expanded under heat so much that it popped off a part of the piston. When I did the engine the first time I didn't touch the pistons so the problem was already in the engine...so I found out the hard way!:D
Nice job indeed! Great video, akin to the CCR hits in terms of quality. Great to see the parts (great AFR heads) and the assembly in progress. Thanks for sharing this 383 SBC.
Everything looks good. Was it a kit? I would have used black or gray silicone instead of that crap blue. Gray is the best. That's what we use at the dealer.
@Badchevee1 Go to AFR'S Website...the have prove of Dynosetups there...my is running on 10.5 Compression and on 95 Octane Gas...It will make 500+ outside of the car on the dyno. It's a whole different story in the car with all the accessories connected, thats for sure.

nice engine build. Like your video of it with cool music well done. Did you have to relieve the bottom of the block to allow enough clearence for the big end bolts with the stroker crank. if so how did you go about it.
ey. i love the look of the engine.. exactly what i want 2 do 2 mine.. i have a pre smog era 327 block bored .30 over and i have barely started on the build but was planning on making it around 500hp 500 ftpnds of tq.. and i was wondering if the xtreme compcams camshaft was the equivalent of the big mutha thumpr becasue i have already purchased it?.. it would be great if you could get back to me .. thanks and again great lookin engine
@crazylazy03 Start with a good baseline around 32° and then work your way up until it starts pinging. This engine is timed at 34° right now, might go up to 36° but I'm not pushing it cause it's not finally tuned.
@aminimaleffort its not amazing, its simply knowing what parts make what for HP.... Ive been around engines all my life. Watch his other video of this engine running, and tell me thats 500HP... i dont think so.
gotta love ccr...........and sbc's to
Nice looking build.
nice bulid
nice block man nice choice in music

My dream is to one day make one of these old big blocks or even a small block Chevy into a direct injected 4 valve engine, just for kicks.
carbs are the best for horsepower. thats why all the race engines are carbureted
Small block Chevy and Creedence, can't get more American than that! Great video/build!
I usually just close photo montages but your choice of music is quite excellent so I stayed. :-) great looking engine. Was it install error that caused it to blow, or was it a faulty part?
loks like you guys had a fun time.. most important part of working on a car! (or truck)
who said it was? the heads are AFR 195cc. They come with either 75 or 65cc combustion chambers.
A 350 with a 400 crank is also a 377. You have to bore it out to get those extra cubes.

LT1 high compression 1970 only in 1971 and 72 the LT1 was low compression 330 hp

Some people dont like other colors then black, Im not worried about spotting leaks as every engines ive built thus far has not leaked.
New friend
hey man i know how you feel. bought an 88 toyota pickup. 2 months later rod bearing #3 welded itself to the crank, wiped the oil pump, that wiped the head, that wiped the cam, that wiped the rockers. the guy before me replaced the timing chain tentioner and left plastic remains in the oil pan. that clogged the oil pickup. i was doing 98 mph down a hill and then it started slowing down. 1400$ later i have new crank head rockers oil pump bearings gaskets 1 rod.sucks dont it :P

@LoNgBeAcHfIvEsIxTwO its a 350. with a different crank. giving it a longer stroke. and putting the displacement up to 383. hope that kinda helped.
Very nice build, but i dont see 500 + HP coming from it

What kinda truck is it? nice job!
It's only because I didn't want to route the hose to the back, so I use the PCV Valve port for refilling the oil as well.
isnt the 383 a small block 400 with a 360 crank board 40 over??
@383TruckRider I'm in the process of building a 388. Was told by Jerry who owns the machine shop that if the piston rings are not file fit properly with the Kieth Blacks that they will expand and rip off the top of the piston. This my first build so any pointers?
looking good, but with carburetor this make a fuel suker: fuel injection is much more efficient and more reliable: see for adaptable injection like Megasquirt...
You think someone who overcompensates with CFM will know about intake velocity?
Excellently done, Bravo gentlemen!
if i had the money to do this...id be fukin dangerous. lol. nice build man
@aminimaleffort What doesnt make a Holley better?... Holley Carbs are the BEST performance carburetors out there.
First nothing wrong with the intake but I did notice a cast crank, did you change that to a steel crank?
your choice of music had me wanting to work on my 383 untill the end then i decided to go work on my pod racer :D
good music man.
Wow, AFR heads!
Nice build good choice in heads. Whats cam profile? Im building a 383 right now and i cant decide what cam to use. I'am using 215cc dart heads with 64cc.

thats cuz all his parts are new.Youl save yourself HALF if you buy used from like craigslist or ebay!
Thanks man, yes it was machined for the crank and rod clearance. A prof. machine shop did it.
Made around 450 HP at the crank on the dyno. So with a engine-dyno setup arround 500+ hp.
Nice build, good use of CCR/TBL
Good vid, my only beef is going with a cast crank on a stroker, not a good idea. I would have saved the cash on the efi set up and spent it on a forged crank. Lower end failures are the most common problem with stroker builds. And contrary to popular belief MSD is JUNK always go Mallory. Congrats on the build though it looks sa weet!!
Done!:) Now runs on a 850 AN Quickfuel with a single GM Performance intake.
Since its a stroker, did you have to do much grinding on the block for clearance?
great! video
u know if you would of got the afr 220s eliminator heads and change cam to a bigger one got a victor jr intake you would be at 653hp also the heads would of cost you the same i got my heads from a guy in tn for $1976.30 with free spring upgrade.
how do like the e-curve? im thinking about getting one for mine

BRILLIANT Vid!! Really enjoyed the pics, parts, choice of tunes and the editing! Good effort Sir. Thx for posting 5/5! =D
Did you do this from an LT1?
junk that carb and manifold! only mistake
yes it runs on Euro Premium 95 octane, compression is 10.5:1.
filler cap to front pcv to rear, keith black pistons in hyper form suck, just plain junk, other than that,nice clean build. on a budget build use the speed pro hypers . thought you might want to know
this is a dumb question but, what are the songs?

wait how exactly did you blow it up. and what pistons did you use. im confused
Nah LT1s come in the 93-97 Camaros and Firebirds.
I like the CCR man and nice looking build

383 with imapala 96 from 0 to 100 km ??? plz
Sorry it's 10:1 not 10.5:1.
Dope ass video
@lgrumour1 Thanks man, good luck on your rebuilt! The block I uses is a 72...so not so far apart!;)
Sorry, but it isnt 10.5:1 with a 75cc head.
Agreed!
@crazylazy03 Start with a good baseline around 32° and then work your way up until it starts pinging.
This engine is timed at 34° right now, might go up to 36° but I'm not pushing it cause it's not finally tuned.
Awesome video! Good job. Thanks
@MRBATHTUB89 Thanks man, it's a '72 4 bolt main 0.40 over.
love me some CCR while watching builds
how would you determine the correct timing for a modified engine like that??
It's made from a '72 4 Bolt main, if thats a LT-1 tell me, I don't know.
@aminimaleffort its not amazing, its simply knowing what parts make what for HP.... Ive been around engines all my life. Watch his other video of this engine running, and tell me thats 500HP... i dont think so.
Really nice motor bro!
omg thats awsome nice work love the vid and the engine i have a 350
with direct fuel injection runs good but its not as cool as yours
@klsnr1 Can absolutely recommend it, very good to run without a box.
