The Boss was specifically created to change that perception forever. It all started when Ford tasked engineers with making the Mustang Boss a leader in the SCCA Trans-Am road racing series.
They chose to use their NASCAR 429 engine as a starting point and engineers set about making a true performance Mustang a reality.
The end result was three different engine configurations and two body variants with styling by new Ford designer Larry Shinoda. The blacked-out hood, racing stripes, and front and rear spoilers made sure that its looks matched what was under the hood.
The engine combined a four-bolt main Windsor small-block with reworked heads from a 351 Cleveland engine with a forged steel crankshaft, connecting rods, and pistons. Ford claimed the Boss would make 290 gross horsepower, but its actual output was likely a bit higher.
The end result was a Mustang that posted the fasted lap time on the Ford track to that date, and a car collectors are clamoring to get into their garages.
