Like Mark Yac said earlier, Pontiac was the NHRA sponsor at the time.
I went through the same crap with many other car models when NHRA will choose to give their own designation although the manufacturer had a different one.

One example is when NHRA designates a car model to a full body style when the car is a Medium size based on the OEM's designation. At the time, the Pontiac brochure had designated the Firebird as a Sports Car.
