whats the difference between a gmc and a chevy
GMC (automobile) Starting in 1920, GMC and Chevrolet trucks are virtually identical except for the grilles and nameplates, though their differences have varied over the years. From 1955 through 1959 small (less than 2 ton) GMC trucks with gasoline V8s were equipped with Pontiac, Buick, and Oldsmobile V8s (the Canadian trucks used Chevrolet engines). GMC had its own line of inline 6 cylinder engines, known as "Jimmy's" from 1939-1959, and their own V6 from 1960-1974 (also a V8, V12). Chevrolet trucks were marketed towards private ownership, while GMC was focused towards commercial uses.
