Offenhauser is one of the greatest names in racing history. Offenhauser speed equipment earned its reputation on the Grand Prix racing circuit during the 1930's and 1940's. Today, you can achieve the same power and performance with an Offy intake, flathead Ford cylinder head or transmission adapter. All Offenhauser intake manifolds are cast from high grade aluminum alloy and are precision machined to equalize fuel distribution to all cylinders for more power.

    This Offy single 4-barrel intake fits the 1932-48 Ford V-8 and features a Carter WCFB bolt pattern. For best results, our techs recommend the Holley 390 CFM 4-BBL which requires the Holley Flathead adapter 135-1935B.

    You may also need to purchase 560-6091, 4" tall carb spacer (in addition to 135-1935B) to use a Holley carb on this intake. The spacer gets the carb high enough so that the base will clear the water hoses.
