Early Bronco Engine Parts

Basic Engine Tech

For the 1966 year model, Ford introduced the Bronco with the 170 in-line 6 cylinder engine. Later the same year, they added the optional 289 V8. In 1969, the 289 was replaced with the 302 V8, which remained the engine of choice until Ford discontinued production of the early Bronco. The 170-6 cylinder was replaced in 1973 with the 200 in-line 6 cylinder and then discontinued in 1974.
