Pontiac Firebird Trans Am
As part of GM, the factory was still under the racing ban. Still, the fans and private teams used many Pontiac products, and the factory wanted to introduce a version for racing. That is how the Firebird Trans Am came to be. To mask its intentions, Pontiac introduced the Firebird Trans Am as a loaded version that featured big-block power from the famous 400 V8 engine equipped with Ram Air III or IV intake system (via Hemmings).
The difference between those engines was significant since Ram Air IV featured a lot of improved engine internals and components. Still, they were both rated at 366 HP, which was understated. However, this particular version with signature white paint, blue stripes, Rally II wheels, and other equipment proved to be a challenging seller, and only 634 Firebird Trans Ams left the factory. Among those, only eight were convertibles.
