I am on the verge of building a 383 for my 72 chevelle. I drive it at least three times a week to and from work and net at least 100 miles a week on it. My 350 is a little tired so I decided to build this. 1997 Vortec block, reusing roller lifters. stroke it out to 383, vortec heads machined for GM hot cam, 10 to 1 compression, eddy dual plane intake, 770 street avenger. I am just wondering if I should go with a dual grind cam to get better exhaust flow for the heads, i know the intake is great but the exaust not as good. Is the compressions to high for pump gas? Carb opinions? lifter opinions? All opinions and criticism please. The rest of my drive train is 700R4 1900 stall, 3.55 posi, 26 inch tire.
