Details

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 carburetors original look. Features such as the choke assembly, Accelerator Pump Rod for Stromberg 97, Adjustable Jets for Stromberg-Style Carbs and cosmetics have all been faithfully retained. Additionally, each carburetor is individually flow tested and inspected for leaks. Perfection is the result!

Aesthetically, the 9 Super 7® 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 thats required is an intake, a 3-Carb Progressive Throttle Linkage, a Edelbrock Uni-Syn Tool, and a little patience. Be sure to include the 9 Super 7® Secondary 2 Barrel Carburetor 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 ourfor more information on using the 9 Super 7® in a 2x2 or 3x2 carb set-up.

On the primary 9 Super 7® carb the throttle shaft extends from carb body .983" and has the hole on the end to pin the linkage. There is a brass sleeve that the throttle shaft rotates in that extends from the carb body .400 and this leaves the useable throttle shaft length of .583. There is sufficient room for progressive linkage and the manual throttle linkage that rotates over the sleeve.

  • 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 oldViton-tipped needle and seat setups
  • Grose-style jet valve wont corrode in modern fuel, something the original needle and seat units cant 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
