The legendary Boss 302 is now available as an entry-level racing engine. The Ford Racing engineers created the X302B and X302E engines to be an affordable way to get your first race car up and running, while still delivering the performance you demand on the track. Constructed from all new parts, the X302B and X302E will run as hard as you demand them to, and work well under their own power, or with forced induction systems.
