We have been running dual H/W's on our 47 Chev Sedan. They are outstanding! Replaced tuned Rodchesters.
Running them on a 235 Chevy 6, Howard's M4F cam, headers, 3:55 gear, and a 5 speed. Got all the carbs, linkage, adapters, and air cleaners from Langdon's Stovebolt.
1. Fuel mileage went from 12/16 to 16/22.
(Car pulls a 26 Ft. travel trailer!)
2. Installation was easy.
(Couple of beers worth of figure'in!)
3. Choke are water or electric.
Electric are a few bucks more. Well worth it!
4. Fantastic throttle responce, fuel milage, and power!
5. No fuel leaks!
6. Burns Rubber!
