1967-1969 Manifold American Motors all V8. Shipping weight 21. 360 degree Equa-flow high rise single quad manifolds. Looking back, over fifteen years ago Offenhauser broke away from the old 180 degree design and introduced a 360 degree design manifold which other manifold manufacturers are now following: You get full benefit of improved passages on every single engine stroke, there is no down time with a 360 deg - your engine operates at full capacity at all times. So-called 180 degree manifolds operate on a part-time basis due to the fact that one side of the manifold is "down" while fuel is delivered to the other side of the engine. Exclusive plenum chamber design of Offenhauser 360 degree Equa-flow Manifold wipes out flat spots in all RPM ranges. Gives you smooth, unrestricted flow of fuel continuously. Each cylinder receives equal fuel flow w/o interrruption or oscillation. You get vibration-free smoothness and power rammed distribution through balanced efficiency. Hands you more power off the line. A fantastic to end improvement. Dyno, Street-Strip Proven. Test results show a 20 H.P. increase at 6500 RPM over competitive manifolds. Fits all regular Holey and Carter AFB 4-barrel Carburetors. California customers - Please note: Vehicles that are sold in state of California and are used for driving on city and state highways must have the emissions equipment working as they were equipped from the factory. If the vehicle came equipped with a single barrel or a 2 barrel carb, and a 2 barrel or 4 barrel is not offered as a factory option in California, then a carburetor of different size and type can only be used for off-road or racing applications.
