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.

But, according to that list the Camaro/Firebird was available with that engine. I know I have had Gen 3 F body cars through my shop with 4 cyls. Been too long to remember which 4 cyl, but as best I can remember that was the only one GM had used in anything but sub-compacts at that time.
