Hey Kyle, i'm building a 383 as well for my 71 chevelle. Here's what i have so far.
4 bolt main block
SCAT stroker crank
forged i-beam rods
forged Federal Mogul pistons
block zero decked, bored .030, internally balanced, clearanced etc.
I am buying Trick Flow Twisted Wedge G2 heads, with Crane Gold Race roller rockers.
As for the cam, i plan on using a Crane hydraulic roller cam retrofit kit with, i think, .510/.519 list and somewhere around 230 duration.
Compression will be just about 10.3
I am also shooting for 450 hp (at least) on pump gas, and i think i will get it, especialy with the full roller valvetrain.
Only time will tell though.
1971 Chevelle 350/TH350 (soon to be 383/4 speed)
