The Ford Motor Company introduced the 460 C.I.D. (cubic inch displacement) engine to the American automotive consumer in 1968. Ford offered the engine as a power-train option in most full-size trucks and luxury passenger cars like the Lincoln. In the late 1960's, many municipal police departments utilized the Ford 460 as the main power plant for their police interceptors; the high-powered engine was an obvious choice for chasing down fleeing criminals. The 460's easy-to-work-on, high-horsepower design was also popular with automotive enthusiasts. Replacing the oil pump drive shaft can be performed with common tools and moderate knowledge of automotive repair.
