Interesting Fact: The Ford Mustang BOSS is a high-performance variant of the base Mustang. Produced in 1969 for one year, the Boss 302 and the Boss 429 were produced for the Trans Am racing series.
The introduction of the Boss series for Mustang began at the same time as the rivalry with Camaro. Standard mustangs were not capable of beating the powerful Camaro, so a new variant had to be created that could emerge victorious. Therefore, the Boss 302 engine was created to win the rivalry.
