Three Chrome 9 Super 7 Carbs, Offenhauser 1074 Intake Kit, 1942-48 Ford V8
                        

This tri power kit uses the Offenhauser Flathead Ford 3x2 intake with 9 Super 7® carbs. It has progressive linkage to give you good driveability and economy, but power when you need it. It includes three carbs, the intake, air cleaners, linkage kit, fuel block, fittings and red fuel line. Assembly required.

Has 4-5/8" carb centers. Features a mount flange at the front of the manifold for Offy fan carrier 560-3499 (sold separately).

The 9Super7 Carb ® makes setting up a multiple carburetor induction system easier than when Strombergs were available new. All that's required to do so with our kits is a Uni-Syn syncing tool and a little patience. Our 3 Carb kits come with one primary carburetor and two secondary carburetors while the 2 Carb kits are both primary carbs.  See our Multiple Carburetor Tech Tip for more information on using the 9 Super 7 in a 2x2 or 3x2 carb set-up.

  • Stainless steel screws and hardware
  • Original troublesome needle and seat replaced by a Grose-style fuel inlet valve to better cope with higher fuel pressures and improved high speed running 
  • Will not stick or dribble like the old Viton-tipped needle and seat setups
  • Extended brass throttle shaft to simplify multi-carb linkage
  • Primary Carb - (1) Middle Position
    • Choke assembly, accelerator pump, and jets have all been faithfully retained and accept standard Stromberg parts

Speedys 9 Super 7 Primary 3-Bolt 2 Barrel Carburetor, Plain Finish
                        

Speedway Motors now offers a reproduction version of one of the most popular carburetors ever used, the original Stromberg 97! Original equipment on '30s and '40s cars and trucks, the Stromberg 97 has long been favored by flathead hot rodders and racers who realized the performance qualities of this timeless fuel supplier.

There have been numerous attempts to reproduce this unit, with little success. "Speedy" Bill Smith of Speedway Motors in Lincoln, Nebraska, took on the challenge to make a great product even better. The 9 Super 7 ® Carb brings this reproduction of the original Stromberg 97 2 barrel carb into the 21st Century!

Speedway Motors has incorporated all of the improvements shown above while maintaining the carburetor's original look. Features such as the choke assembly, accelerator pump, main jets and cosmetics have all been faithfully retained. Additionally, each carburetor is individually flow tested and inspected for leaks. Perfection is the result! 

Aesthetically, the 9Super7 is nearly identical to the stock unit, minus the large 97 logo that appeared on the side and the patent numbers found on the float bowl area. Upgraded internal parts include; the float, needle, and seat. Jetting and power valve settings remain as they were for the original 97 carbs as well as the cfm and vacuum specs.

The other similarity that the 9 Super 7 shares with the original 97 is the setup and tuning necessary to yield a well-running machine. While perhaps not as simple as bolting on a single four-barrel, the 9 Super 7 makes setting up a multiple carburetor induction system easier than when Strombergs were available new. All that's required is an intake, a linkage system, a Uni-Syn syncing tool, and a little patience. Be sure to include the Secondary 9 Super 7 when installing multi-carb setups. Our 3 Carb kits come with one primary carburetor and two secondary carburetors while the 2 Carb kits are both primary carbs.  See our Multiple Carburetor Tech Tip for more information on using the 9 Super 7 in a 2x2 or 3x2 carb set-up.

  • All-new tooling for crisp, flawless castings
  • New aluminum base assembly allows for cooler fuel temps and better fuel efficiency as compared to the original cast iron design
  • Stainless steel screws and hardware
  • Choke assembly, accelerator pump, and jets have all been faithfully retained and accept standard Stromberg parts
  • Features original Stromberg 0.97" venturi diameter
  • Modern Nitrophyl float and Neoprene gaskets
  • Original troublesome needle and seat replaced by a Grose-style fuel inlet valve to better cope with higher fuel pressures and improved high speed running 
  • Will not stick or dribble like the old Viton-tipped needle and seat setups
  • Grose-style jet valve won't corrode in modern fuel, something the original needle and seat units can't do
  • Comes with a No. 65 power valve and 0.045" main jets, identical to the stock 97
  • Extended brass throttle shaft to simplify multi-carb linkage
