1965-76 Oldsmobile Big Block V8; 400-425-455 cid; Offenhauser 360 Degree Equa-Flow Intake Manifold; Dual-Quad; Square Bore; Low-Rise

Offenhauser 360 Degree Equa-Flow Dual-Quad Low-Rise intake manifolds make good use of Offy's 360 degree technology to feed all cylinders evenly and make more power. This results from their single-plane configuration, with its unique split-plenum chamber and tuned intake runners. That combination delivers the fuel-air charge evenly to all cylinders for more power without flat spots. Edelbrock Performer series and Carter AFB carburetors are recommended. Some applications cannot mount Holley carbs in any manner, or clear HEI.

• Fitment Note: This manifold accepts square bore, Holley, Carter AFB, Edelbrock style carburetors. It will NOT accept spread bore, Quadrajet type carburetors.
