"The model “40” was the first generation of the Stromberg dual-downdraft or two-barrel design and saw limited use on some of the early 1934 V-8s. The 48s were the original-equipment carburetors for the 1934 and 1935 Ford flathead V-8s. The 97s were offered on the 85hp V-8s from 1936 to early 1938, and the 81s powered the 60hp V-8s in 1937 and ’38. Stromberg also produced a model “L” which had a one-inch venturi and was used only on 1936-’37 Lincoln V-12 engines."
