The Trans-Am Series was initiated in 1966 in the early days of the Pony Car era as a derivative of the SCCA A and B Sedan Club Racing classes. The idea was to use ommercially produced cars that were allowed a moderate degree of modification. Trans-Am cut into 2 basic classes:The under 2.0 liter class, which brought together a great collection of Alfa Romeos, BMWs, Datsuns and more, but the real draw was the over 2.0 liter class - the big American V8s, that were limited to 5.0 liters.
In 1967, a privateer named Bud Moore partnered with Mercury to develop Cougars for the series. By the conclusion of the season, the Bud Moore Cougars, driven by Dan Gurney, Peter Revson, and David Pearson won 4 races of 12 - just as many as Ford's vaunted Mustang. Bud Moore's Cougars came within 2 points of winning the championship in 1967. He had Ford's attention.
