Offenhauser 1078 Details

This Offy single 4-barrel intake fits the 1949-53 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.

This intake moves the generator and fan to the driver's side 3/4".  This will require modifying an original fan shroud if one is used and if a belt/driven fan is being utilized.

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.

  • For 1949-53 Ford Flathead, 4-barrel carbs 
  • Requires Holley carb, adaptor, and spacer for best results
  • Single Plane

Overall Assessment

Our product has been appreciated by customers mainly for its quality and functionality. Customers have noted that it fits perfectly on a flathead V8, enhancing the look and performance of the engine. Its design, which has been described as efficient, allows 12 bolts to be utilized for adequate and secure placement. Furthermore, the manifold is expected to improve engine breathability when paired with a 4-barrel, Fenton headers, and dual exhaust system. While certain holes may not align with the engine block, it doesn't seem to detract from effective operation. Overall, the product exemplifies practical use and high-quality material.

The manifold bolt pattern only allows 12 bolts to be used. There are 7 holes where there is no threaded hole in the block. There are two locations where the block has holes, but the inlet has no boss. The 12 useful holes appear adequate to secure the manifold.
