Offenhauser 1075 1949-1953 Ford Flathead Regular Dual Intake Manifold
Carbureted Fuel System Type, Single Plane Intake Manifold Type, Two Carburetor Quantity
- Accepts 3-bolt carbs
- 4 3/4" carb centers
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"
Specifically designed to fit ’49–’53 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.
