Offenhauser 1075 Details

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

The generator may not fit into the stock location due to the clearance issue with the carburetor.  The generator can be relocated to the passenger side using bracket # 325-1146. If using a GM alternator, use our chrome 916-67909 or plain 916-67910 bracket.

  • Carb Centers:  4-3/4"
  • Carb pads are angled as they were on stock 49-53 intakes
  • Front drivers side accessory hole is for draft tube and measures 1.25"
  • Rear drivers side accessory hole is for oil fill tube and measures 1.375"

Overall Assessment

Customers highly value our product for its quality, practicality, and superb fitment. They've particularly praised its aptness for flathead engines and its excellent compatibility with air conditioning compressors. The manifold's polished intake runners also add to its user-friendly and efficient design. Some customers had to apply creativity in adapting for the generator due to the variation in carburetor spacings, reflecting the product's versatility. One significant highlight is the direct improvement it provides to engines, deemed so essential that "no flathead should be with only one carb." So, in comparison with competitors, customers positively recommend our product for its outstanding performance, superior features, and proven benefits.

Very pleased with the manifold but there is a variation between the early and late model carburettor spacings which you can't see in the catalog. This required some ingenuity to adapt for the generator.

This is a high quality intake that looks as great as it performs. No flathead should be with only one carb.
