Drilled for AFB and Holley Carburetors. Shipping Wt. 22 lbs. 360 degree Equa-Flow Offenhauser.
Produce more horses. While the highly-advanced new Offenhauser 360 deg manifolds are not twice efficient as the old 180 degree models, they are certainly in a class by themselves.
Note: We recommend AFB carbs for most Dual Quad Manifolds due to carb clearance. In order to use Holley Carbs it may be necessary to use our carburetors no. 5880 or no. 5832. Be sure and check.
