    Intake manifold is new or appears to be new and never mounted to a block (not an expert but it's clean enough to eat off of). Bought this for the wrong year block and have no use for it. Email or PM me if you are interested.

    This intake retails at Jegs.com and Summit.com for $305.95. Looking to get what I paid for it, $200 + shipping (very light due to being made from Aluminum).

    Smooth, unrestricted fuel and air flow.
    Offenhauser's 360 Degree Equa-Flow Single Quad High-Rise intake manifolds feature a 360 degree design for full-capacity operation. This combination of unrestricted fuel-air flow and a divided plenum means no flat spots throughout the entire rpm range. What does all this mean? The equal fuel flow to each cylinder increases horsepower and torque, while evening-out individual cylinder temperatures. Power bands start as low as 1,800 rpm with a small carb and climb all the way to 8,800 rpm with a big one.

    These are the only pictures I have available at the moment. The center divider goes all the way to the bottom of the manifold and both sides are cut to the same level.
