The Boss 302 Mustang (Hi-Po) engine is manufactured by taking the Ford Windsor (assembly plant) block from the 289 then adding the 351 Cleveland head with its larger valves to create the 302. This is an engine that will be formidable competition for the Chevy small blocks and any other competition in the SCCA Trans-Am series. The resulting 302 (5.0 L) engine is the maximum size allowed that will fit the homogenization guidelines of the Trans-Am series. The Boss 302 also has improved aerodynamics and superior handling with the intent of eclipsing the Camaro, not only on the race tracks, but on the street as well.
