Offenhauser 1079 1932-1948 Ford Flathead 4-Barrel Intake Manifold
                        

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.
