For sale is a vintage Offy dual plane aluminum intake manifold for a Ford 351 Windsor. This intake manifold is in very good condition. This unit is used but does not have a lot of wear and tear. All mating surfaces are nice and straight. There are no cracks, breaks, or stripped threads. This was installed on a motor and worked great- it is much lighter weight than the stock iron unit and really promotes nice low and mid-range torque. It is an excellent choice for a street oriented 351w. See pictures, if you need any more pictures or have any questions, please ask!
