Ford whips out the Boss 302 to show the jaw-dropping side of the Mustang every time the muscle car war heats up. By far the coolest part of this rare Mustang is the venerable Boss 302 engine. While there have been two generations of the Boss 302 Mustang, there are actually three different families of engines carrying the Boss 302 moniker. The first generation of the engine powers the 1970 Boss 302 Mustang. It is a hybrid of two small-block Ford V8 engines. It gets its block from the Ford Windsor engine and its heads from the Ford Cleveland engine. While this engine produces 290 horsepower, the second-generation engine in the 2013 Boss 302 Mustang delivers 444 horsepower with the same 5-liter displacement. However, Ford Racing made a set of crate engines carrying the Boss 302 badge in the late 2000s. These can go in any Mustang and have displacements ranging from 5-liter to 5.9-liter, with power delivery ranging from 340 to 500 horsepower.
