I've got an 85 chevy 3/4 ton 4x4. It's got a 6" lift, 35" tires, and 4.10 gears. I am almost finished building up my motor. It's a 350 bored .30 over with trw flat top pistons, double hump heads, mild porting and polishing, milled, edelbrock performer rpm intake, edelbrock 1406 600cfm carb, headmann headers, crane roller rockers and pushrods, and dual flowmaster 40's. I need a camshaft. I drive it on the street but mostly take it muddin and rockcrawling. I want some really low end power and will spin the mud off the tires quickly. What kind of cam do i need?
