1970 Ford Mustang - Classic Car Price Guide

History of the 1969-1970 Ford Mustang

Ford unveiled another restyle in 1969, but it was lost in the shadows of three new models: the Mach 1, Boss 302 and Boss 429. Various competition-style appearance items and the GT-handling suspension were standard for the Mach 1, with engine options including the 351-cid small-block, 390 big-block or 428 Cobra Jet. Two race-ready Boss V-8s, the 302-cid small block and 429-cid big block were predictably the hearts of other two hot-to-trot pony cars. The Boss 302 produced 290 horsepower, and its 429 cube big brother made 375 horses. Handling was the main strength of the Boss 302, which was created to race Chevrolet's Z/28 Camaro on SCCA Trans-Am road courses. The idea behind the big, bad Boss 429 involved homologating its exotic V-8 for NASCAR tracks, where it did its darndest beneath mid-sized Talladega hoods. Both Boss Mustangs were built through 1970. Boss 302 production was 1,628 in 1969 and 7,013 in 1970. Boss 429 numbers were 857 in 1969 and 499 in 1970.
