The first design was produced from 1956 through 1967. An Electrojector version was to be the first commercial electronic fuel injected (EFI) production engine for the 1957 model year.
The second design was introduced in 1966 and became available in several displacements over the years as well as in high-performance and racing versions.
In 1987, Chrysler Corporation acquired AMC and continued manufacturing the AMC "tall-deck" 360 cu in (5.9 L) version until 1991 for use in the Jeep Grand Wagoneer SUV.
