Chevrolet introduced the Corvan in 1961 as a direct competitor to the VW van, with a larger more powerful rear engine. It came in a variety of versions, the panel version, window van (Greenbrier) and even a pickup (Rampside). However the Corvans never could compete with the Econolines introduced at the same time and production was stopped completely in 1965. The Chevy / GMC vans were introduced in 1964, with engine placement similar to the Econoline. In 1967 they changed the styling slightly. The forward control Chevy/GMC vans were fazed out in 1970.
