The '''LA engine''' is a family of [[overhead valve engine|overhead-valve]] small-block 90° [[V engine|V-configured]] [[gasoline engine]]s built by [[Chrysler Corporation]] between 1964 and 2003. Primarily [[V8]]s, 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 chamber]]s are [[wedge]]-shaped, rather than [[polyspheric]], as in the A engine, or [[hemispherical combustion chamber|hemispheric]] in the Chrysler [[Chrysler Hemi engine|Hemi]]. LA engines have the same {{cvt|4.46|in}} 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 "[[Chrysler A engine|A]]" engine it was closely based on and shares many parts with<ref>{{cite web |last1=Lotspeich |first1=Justin |title=Poly A Block Parts Interchange |url=https://poly318.com/poly-parts-interchange.html |website=Poly318 |publisher=Poly318}}</ref> was nearly 50 pounds heavier.<ref name="Willem Weertman">{{cite web|title=Willem Weertman, Chrysler engine designer |url= http://www.allpar.com/corporate/bios/weertman-chron.html |publisher=Allpar |access-date=17 December 2017}}</ref> 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.<ref>{{cite web |last1=Lotspeich |first1=Justin |title=Poly A Block History |url=https://poly318.com/poly-318-history.html |website=Poly318 |publisher=Poly318}}</ref>

The basic design of the LA engine would go unchanged through the development of the "[[#Magnum engines|Magnum]]" upgrade (1992–1993), and continue into the 2000s with changes to enhance power and efficiency.<ref name="Willem Weertman" />
