The Nash Rambler engine is a family of straight-six engines that were produced by Nash Motors and then American Motors Corporation (AMC), and used in Nash, Rambler, and AMC passenger cars from 1940 through 1965. It was succeeded by the AMC straight-6 engine in 1964, a completely new design. The engine evolved in several displacements and was built with two different valvetrains. The engine was originally of a flathead layout; an OHV version was introduced in 1956 although the flathead continued to be available. A version of the OHV engine with an aluminum block was introduced in 1961.
