Chrysler LA engine

The LA engine is a family of overhead-valve small-block 90° V-configured gasoline engines built by Chrysler Corporation between 1964 and 2003. Primarily V8s, the line includes a single V6 and V10, both derivations of its Magnum series introduced in 1992. A replacement of the Chrysler A engine, they were factory-installed in passenger vehicles, trucks and vans, commercial vehicles, marine and industrial applications. Their combustion chambers are wedge-shaped, rather than polyspheric, as in the A engine, or hemispheric in the Chrysler Hemi. LA engines have the same 4.46 in (113 mm) bore spacing as the A engines. LA engines were made at Chrysler's Mound Road Engine plant in Detroit, Michigan, as well as plants in Canada and Mexico. The "LA" stands for "Light A," as the 1956–1967 "A" engine it was closely based on and shares many parts with was nearly 50 pounds heavier. The "LA" and "A" production overlapped from 1964–1966 in the U.S. and through 1967 in export vehicles when the "A" 318 engine was phased out. The basic design of the LA engine would go unchanged through the development of the "Magnum" upgrade (1992–1993), and continue into the 2000s with changes to enhance power and efficiency.
