I found out that I have a 383 in my 79 Camaro. I was wondering what type of horse power I would be making and if I switched from 76cc to 64cc heads would do. The engine is a 1970s 350 bored 30 over with flat toped pistons. Forged rods and a 400 crank with a push on harmonic balancer. It has a .015" head gasket and old after market over the counter 882 heads with new valve job and springs. Has a summit racing 1103 cam. Holley 600cfm, edelbrock eps intake, hei, 30w race oil with a 4.3 high torque starter. Connected to a 4 speed close ratio Saginaw with 11" clutch and hurst shifter with posi and 4.11s. Thanks
