"Chrysler actually made three basic versions of the 318: the first, polyspherical-head version in the 1960s -the second, LA family in the late 1960s and through to the late 1980s/early 1990s - and the final Magnumfamily, which is still in production for light trucks and Jeeps. The 318 may be discontinued as the firstcompletely new Mopar V-8s since the 1950s are introduced. The 318 came as the standard V-8 for many years, and was the optional V-8 on Valiants and other small cars in its earlier years, when the 273 was still around. It was used as a police engine, mainly in the M-bodies (Diplomats and Gran Furys), and was often the largest engine available in Valiants and theirdescendents, the Volare/ Aspens and Diplomat/Gran Furies. From its introduction in 1967 through its conversion to EFI, the 318 was generally treated as a two-barrel workhorse. With the 340 and 360 around, the 318 kept its "economy carb" from 1968 through 1978, when it got a four-barrel option. Despite its "economy engine" status through many years, the 318 started out as a performance option and ended as one in Chrysler's final police cars, the M-body Diplomat and Gran Fury. (Unfortunately, without rear-wheel-drive sedans to put them in, the Magnum treatment never made it into the police force). Though the 318's performance came between the GM 305 and 350, it never seemed to have the oil-burning and smoke-producing qualities of those engines. Like the slant six, the 318 has shown itself capable of great abuse at the hands of those non-oil-or-air-filter-changing bozos who so often end up behind the wheels of Mopar cars and light trucks. Rather than coming to the same (performance-oriented) end as the 305/350, though, the 318 was destined to be phased out of cars entirely, and to be used in pickups and Jeeps. Though the modern version has been raised to its potential, with sufficient fuel making its way into the cylinders and more efficient burning, the 318 was rarely really full appreciated by Chrysler (the pre-1972 340 years are a major exception)."
