I am building a Chevy 383 Stroker. I have World Sportsman II heads,Pertonix HEI distributer, Holley Street Avenger 770CFM. TH 350 Trans with 2100 Stall Converter & 3.73 Posi rearend. This will be going into a heavy 4000# 1976 Monte Carlo. I know I need a lot of low and midrange torque to get this beast moving. This engine will be for high performance street use. I will be using a Hydraulic Cam since a Roller is so expensive. According to the Engine builder a cam of about .500 lift should be used. I do not know the exact cam specs yet. As always thanks for the help. Joe

Will Pocket porting add much power in RPM range of Idle to 5500 RPM ?

in those heads you won't feel the improvement below 5500, keep your .050 duration below 230,( use as wide a centerline as you can for the broad curve,) if you want functioning power brakes,(or use a vac can)and as much lift as your heads and valvetrain will allow. the 3.73 gear will help with streetability.

Thats a lot of head and carb for such a mild engine, you've got circle track equipment there man. Unless your going for looks the stuff you have there won't start building power until beyond 4000 rpm and thats only if you cam it for that.

Is this what you want?

The Machine shop I am working with builds Circle Track, Drag Racing and Marine Racing engines. He is building the Short block and using a "Drag Racing cam", he told me working with the this cam vacuum will not be a problem.

Thanks for the help.
