A Brief History
In the late 1960s, Ford was determined to dominate the SCCA Trans-Am racing series, a fiercely competitive arena showcasing the best of American muscle. To meet homologation requirements for the series, Ford needed to produce a certain number of street-legal versions of their race cars.

However, enthusiasts often claim that the actual output was closer to 350 horsepower.
