My brother and I found that the offenhausser two carburetors manifold it's a good idea to get better performance at a low cost. What was initially difficult was to find parts of the linkage adjustment of the carburetors and other difficulty was to make chokers work perfectly , we solved the problem by making a sheet steel base for the first carburetor welded to the exhaust manifold. We use two carter carburetors and now we slowly found the ideal adjustment of the floats for gasoline consumption, currently the car gives us an average of 6 miles per litter in the city and on the road an average of 8 miles per liter at a rate average of 60 milles/hr. The engine works smoothly and the car gets a very docile handling, I also own a 1968 Valiant with 318 engine with a four barrel carter termoquad carburetor, as well as other modifications, a 727 gearbox with converter and a 3:51 rear axle, I do not miss it when I drive my 1962 225 Valiant with the offy dual carburetor, It is not as explosive as the other valiant at startup, but is excellent for rapid traffic management, and excelent for long road trips. I completely recommend it.
