Offenhauser intake manifolds are cast of high grade aluminum alloy, and
expertly engineered and precision machined. These quality aluminum manifolds provide increased power, economical operation, and a smoother, better running engine. Equalized fuel distribution to all cylinders allows engines to operate at maximum efficiency throughout all ranges of RPM.
Specify early (32-48) or late (49-53) engine and select from these four configurations:
Note: If you use an early manifold on a late block or vice versa, the crankcase ventilation will not work as designed. You
may be able to overcome this by installing a PCV.
