, sharing much the same body sheetwork, except for nameplates and grilles – though their differences, especially engines, have varied over the years. GMC advertising marketed its trucks to commercial buyers and businesses, whereas Chevrolet's advertising was directed towards private owners. Beginning in 1928, GMCs used Pontiac's 186 cu in six-cylinder engines in their lighter trucks. Medium-duty trucks relied on Oldsmobile straight-6 engines, while the heaviest trucks used GMC's own "Standard Big Brute" engine. From 1939 to 1974 GMC had its own line of six-cylinder engines, first the inline sixes known as "Jimmy's" from 1939 to 1959, and then their own V6 from 1960 until 1974, of which a V8 and a V12 version also existed. Additionally, from 1955 through 1959, the less than 2-ton, domestic GMC gasoline trucks were equipped with Pontiac V8s, and
