"The mid-1955 introduction of Chevrolet's Cameo Carrier pickup truck helped pave the way for the El Camino. Although it was a model variant of Chevrolet's Task Force light-duty pickup, the Cameo offered an array of car-like features that included passenger-car styling, fiberglass rear fenders, two-tone paint, a relatively luxurious interior, as well as an optional V8 engine, automatic transmission, and power assists.[2] As always, there was a GMC version offered during the same time, called the GMC Suburban Carrier with the same features offered on the Chevrolet. In 1957 a special version was made for GMC to be shown at national car shows called the Palomino,[3] which had a Pontiac 347 cu in (5.7 L) V8 installed, borrowed from the 1957 Star Chief." Wikipedia
