    Does anyone know what the best ignition timing is for a 350 with a holley carb,Edelbrock manifold and Hooker headers mated to a 4 speed manual trannie. This is a truck in Belgium and has no emision control equipment left on it.

    8 degrees before top dead center for a start, If it pings (detonates) back it off to 7 or 6 before top dead center. If does not ping at 8 degrees before top dead center move it to 10 before top dead center.
