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). http://store.summitracing.com/partdetail.asp?part=ofy-5874&view=1&N=700+150+ Brand: Offenhauser Product Line: Offenhauser 360 Degree Single Quad High-Rise Intake Manifolds Part Type: Intake Manifolds, Carbureted Part Number: OFY-5874 Engine Block Style: Stock/OEM standard deck Carburetor Quantity: Single Intake Style: Single plane with divider Intake Finish: Natural Intake Material: Aluminum EGR: No Intake Manifold, 360 Degree, Split Single Plane, Aluminum, Natural, Square Bore, Buick, 400/430/455, Each 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.

Intersted can you provide better pic of center divider. Is center divider cut low? this might work for my 3 Barrel holley thanks
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.
