About Mopar
Mopar (short for MOtor PARts) is the automobile parts and service arm of Chrysler LLC. The term was first used by Chrysler in the 1920s and has been in continuous use ever since.
Mopar has passed into broader usage among car enthusiasts as an unambiguous reference to the Chrysler parent company, as the Chrysler name also refers to a company marque. The term has thus become an inclusive word for any Chrysler-owned brand, but generally any Dodge, Chrysler, Plymouth, Imperial, or DeSoto, and later American Motors (AMC) or Jeep, vehicle. Thus, for example, a car club for owners of any Chrysler Corporation vehicle might describe itself as a club for "Mopar enthusiasts."
The term Mopar is most closely associated with the muscle cars produced by Chrysler, Dodge, and Plymouth during the 1960s and into the early 1970s. They were famous for the wide selection of engines and carburetor combinations available for their cars. Class "LA" engines included the 273, 318, 340, and 360, and were predominantly used in the base model cars. Class "B" and "RB" included the high performance engines including the 383, 400, 413, 426 wedge, 440, and 426 Hemi. The 440 engine was available with a single four-barrel carburetor (magnum) or three two-barrel carburetors (six pack). The Hemi (named for its hemispherical combustion chambers) still serves as the pinnacle of power in Mopar automobiles.
