What's in the Box

Info

Said to be its most popular flathead intake, Offenhauser’s 2x2 Regular intake has closely spaced carbs that will clear the stock generator. The Offy regular dual intake accepts two 3-bolt carbs. Great addition to a street oriented engine. Has 4-3/4" carb centers.

Has room for generator in stock location, but generally requires an offset bracket. If using a GM alternator, use our chrome 916-67909 or plain 916-67910 bracket.

  • Carb Centers:  4-3/4"
  • For 1932-48 Ford Flatheads

 

Notes

Specifically designed to fit 1932-48 models, which allowed Offy to move the carbs 1-inch further forward compared to the competitors intakes. This relocation was worth 2.8 more peak horsepower over the competitors but at the cost of 1.2 lb-ft less torque. Overall, the Offy had slightly better overall average power and torque numbers. This twin carb set up produces better numbers than Offy’s single four-barrel intakes.

Note: If used with our progressive linkage kit, the front carburetor will need to be set as the primary.
