In 1969, Pontiac wanted to present a model to homologate for Trans-Am racing. To mask its intentions, Pontiac introduced the Firebird Trans Am as a loaded version. It featured big-block power from the famous 400 V8 engine equipped with a Ram Air III or IV intake system (via Hemmings).
However, with its signature white paint, blue stripes, Rally II wheels, and other equipment, this special version proved to be a tough seller. So they sold only 634 Firebird Trans Ams. Among those, only eight were convertibles.
