ALL  DUAL PORT MANIFOLD - GM - Part Number 6167-DP
1976-1978 Dual Port Manifolds Buick/ Olds/ Pontiac 231 C.I. Will not fit Tall Port heads due to port size. Detroit's re-discovery of the V-6 doesn't surprise Offenhauser engineers at all. We've been making 360 deg Equa Flow Manifolds for the V-6 since its original introduction in the early sixties by Buick. Now also 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 4bbl carb from 400 CFM to 600 CFM depending on whether it's for street or competition.
