Anyone With Chevy 350/383 Knowledge?

Actually the 383 Chevy is a great streetable, torque engine perfect for trucks, 4Xs, and heavy cars. U are correct in that they used a crank from a 400sb. They cut the main journals down to fit the 350 block. However, these cranks were never forged so the guys building big HP didn't use them. A less known version was the 373, which used a forged steel 350 crank in a 400 block. Bigger bore, shorter stroke high winder! The only drawback was the siamese cylinder bores in the middle of the block which could cause overheating in extreme conditions as there wasn't a water passage between them. Man do I miss my Chevys!

My dad and I build a 396 stroker out of my stock 350 I removed from my old truck, it actually ended up being comparable in price with building a 383 and made 530hp on pump gas with mild compression. Those extra cubes allowed us to use a more streetable cam and lower compression to achieve similar power to what a higher compression radical cam 355 or 383 would have made. Pretty sure it was eagle or lunati that made the rotating assy. kit for the 396, not sure though.

HA HA I can take a hint. It's a 68 Firebird with a 400 punched .030 over. It has a set of mildly ported Ram Air III heads, a Crower 60243 cam, Edelbrock Performer RPM intake, and a modified Rochester Q-jet carb. It has a Muncie M-20 4 speed trans and it has a 12 bolt posi rear with 3:73 gears.

Oh man! That is CLEAN. You need to bring that over here so we can go for a cruise!

my dad runs both breathers in his chevelle with a 355 (350 punched out 30 over)

I don't believe you either. I'm going to need to see pics of that too.

Lol I'm beginning to notice a trend here . . .

This is my old 357ci small block with ported and polished dart vortec heads (before I swapped it out for non-centerbolt style patriot heads and bigger cam). Truck also has a built 4L60E, built 10 bolt with 3.73s, TCI fully programmable trans controller, 454ss interior and custom dash w/ auto meter, about 1000 hours of body/paint work, etc . . .






Dad's 355ci small block nearly identical setup internally. 64 chevelle REA SS convertible 4speed 12 bolt, he's had the car since 1975 when he was 16. It's gonna get the surgery for a 396 small block transplant next time I go home to visit.
