Hey so this is my first build and I'm trying to do it right the first time.
I'm building a 383 stroker for my 1986 Z28. Heres what I have

L98 block bored .030 over
Stroker assembly from enginekits.com
crank stroke 3.75
5.7 forged rods
12cc dished pistons
splayed main caps
novi 1000 with 10-11lbs pulley
1.6 crane gold rockers
hardened pushrods (stock length)

So with 64cc chambers the compression ratio should be 10.2:1 :yikes:

I know thats way too high to run 10psi so I want to know what size chambers should I be looking for 68cc, 72cc or..... size runners 190cc or 210cc?

Also what size cam? I want it to be a hydraulic roller cam.

I was thinking and airgap intake

btw it is a carbed motor. Unsure on carb setup aswell.

All help would be really appreciated. :beer:

That is prefect compression for boost.

I've been told from just about everyone 9:1 or 8:0:1 is the better compression ratios to go with.


why is it you think 10.2:1 compression is good for 10lbs of boost????

Carb size?
cam size? I was looking at the extreme energy cam 1,800- 5,800
Intake .510
Exhause .540
230int/244exh
those numbers are for factory 1.5 rockers and I'm going to be using 1.6
