The 1970 Ford Mustang BOSS 302 serves several purposes… with the first being to make the Mustang legal for competition in the red-hot SCCA Trans AM road race series  The other purpose of the BOSS 302 was purely to provide us wannabe racers with an at-home-player version of the Trans AM racer that was ready to rock right off the showroom floor.    These cars featured all the style of the track-only cars, but were 100% street legal.    And they weren’t just for looks, either… the BOSS 302 has a long list of performance improvements over the base model Mustangs.  From The Brothers Collection.
