With styling tweaked by newly arrived Ford designer Larry Shinoda, the 1969 Ford Mustang Boss 302 sported front and rear spoilers, a blacked-out hood treatment, and racy side stripes for a look that screamed performance. Under the bodywork, the Boss 302 didn’t disappoint. Its engine combined a four-bolt main Windsor small-block with reworked heads from the then-new 351 Cleveland engine. A forged steel crankshaft, connecting rods and pistons rounded out the reciprocating assembly. The result was a free-breathing, high-revving powerplant making what Ford claimed was 290 gross horsepower – though actual output is estimated to be significantly higher.
Ford engineers also thoroughly massaged the Mustang’s suspension in an effort to meet then-boss Semon “Bunkie” Knudsen’s mandate to “build absolutely the best-handling street car available on the American market.” Stiffer springs and shocks, special sway-bar tuning, a stiffened chassis and wide tires led to the fastest Mustang ever to lap the Ford test track up to that point.
