SuccessorFord Boss 351 V8

The Ford Boss 302 (formally the "302 H.O.") is a high-performance "small block" 302 cu in (4.9 L) V8 engine manufactured by Ford Motor Company. The original version of this engine was used in the 1969 and 1970 Boss 302 Mustangs and Cougar Eliminators and was constructed by attaching heads designed for the planned 351 Cleveland (which debuted the following year) to a Ford small block.[1] The construction was aided by the two engines sharing a cylinder head bolt pattern, though the Boss heads had to have their coolant passages slightly modified.[1]

An entirely new Boss 302 engine was introduced for the 2012 Ford Mustang using a variant of the Ford Modular engine.
