The GMC Sprint is a coupe utility/pickup that was produced by GMC for the 1971–1977 model years. The Sprint was renamed Caballero for the 1978 model year, and produced through 1987. The rear-wheel-drive car-based pickups were sold by GMC Truck dealers primarily in the United States and Canada as the GMC version of the Chevrolet El Camino. Trim designations, emblems, and wheel trim differentiate the GMC from the Chevrolet. The vehicles were built on the General Motors A platform through 1981; for 1982, it was re-designated the G platform as the A platform switched to front-wheel drive.

The Chevrolet "big block" engine is a term for a series of large-displacement, naturally-aspirated, 90°, overhead valve, gasoline-powered, V8 engines; that were developed and produced by the Chevrolet Division of General Motors, from the 1950s until present.
