Offenhauser 1090 Details

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
