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 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, jets and cosmetics have all been faithfully retained. Additionally, each carburetor is individually flow tested and inspected for leaks. Perfection is the result!

Here's what others are saying about the Speedway Motors 9 Super 7 Hot Rod Carburetor:
We dyno tested the Speedway 9 Super 7 carburetor back-to-back with an original Stromberg 97 on a 355ci small-block Chevy. Both carburetors performed equally well, with comparable power. The 9 Super 7 delivered a slightly richer fuel mixture than the stock 97 - which is a good thing with today's poor quality pump gas. This is a smooth carburetor - it does everything right. I think it is a very good piece.

We tested the 9 Super 7 on Bob Everts' '32 Ford sedan delivery, which has a stock '36 Flathead V8 previously equipped with a Stromberg 97. We removed the Stromberg and installed the 9 Super 7. We hit the starter and it fired up immediately on a cold, unstarted engine. It idled perfect with no adjustments or leaks. After a short drive, we shut the car off for a few minutes; it restarted immediately upon engaging the starter button. Overall driveability was excellent. Bob has kept the 9 Super 7 on his '32 and reports that it is still running great.
