Detroit s re-discovery of the V-6 doesn t surprise Offenhauser engineers at all. They have been making 360 Equa-Flow manifolds since its original introduction in the early sixties by Buick. Now available is the Dual Port design which gives the V-6 extra punch in low to mid RPM s and better gas mileage without altering the emissions. Uses standard 4 bbl carb from 400 CFM to 600 CFM depending on whether it s for street or competition
*emission control adapter kit sold separately (will not fit Tall Port heads due to port size)
