I have a set of 1990 aluminum heads (#10088113) that I am putting on a 383. The camshaft is a Comp 262H-10, w/ 270/280 degree and .462/.469 lift. I have an Edelbrock dual plane 2701 and a 600cfm Edelbrock for carb.. The manifold and heads are matched as close as I can get them. Also headers will be matched up upon install. All put into a 1979 Caprice 2dr. w/3.73 and a tricked turbo 350. Any thoughts or suggestions? Its a street machine mostly.
