The Chevrolet C20 was a variant of the 2nd Gen C/K that was introduced for the 1967 model year. The C20, which was a 3/4 ton, rear wheel drive pickup truck, was offered with two inline six engines, as well as V8 powerplants, which included small or big block options. These engines ranged from 155hp to 325hp in power, with drive sent to the rear wheels through manual or automatic transmissions. The C20 was available in two bed configurations, with the sleek Fleetside bed, or the fendered Stepside bed being the two options. Notable trim offerings included the Cheyenne and CST (Custom Sport Truck). Production of the 2nd Gen Chevrolet C20 ended in 1972 with the introduction of the Third Generation Chevrolet C/K.
