The Willys L134 (nicknamed Go Devil) was a straight-4 automobile engine made famous in the Jeep produced in World War II. The engine displaced 134.22 cu in (2,199.5 cc) with a 3.125 in (79.4 mm) bore and 4.375 in (111.1 mm) stroke, a very undersquare design.

The L134 was phased out by the F-head Willys Hurricane engine beginning in 1950.
