The '''Ford Boss 302''' (formally the "'''302 H.O.'''") is a high-performance "small block" {{cvt|302|cuin|L|1}} [[V8 engine]] manufactured by [[Ford Motor Company]]. The original version of this engine was used in the 1969 and 1970 [[Boss 302 Mustang]]s and Cougar Eliminators and was constructed by attaching heads designed for the planned [[Ford 335 engine#351 Cleveland|351 Cleveland]] (which debuted the following year) to a Ford small block.<ref name="maf-oct2010"/> 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.<ref name="maf-oct2010"/>

An entirely new [[Ford Modular engine#Boss 302 .28Road Runner.29 Variant|Boss 302 engine]] was introduced for the 2012 Ford Mustang using a variant of the [[Ford Modular engine]].
