Turbo Rocket-Oldsmobile COPO?

[69SSZL1]

Finally, after all these months of working on it, I took the Turbo Rocket powered Jetfire out for a drive. It runs great, and really moves. I am really impressed with the engineering Oldsmobile put into these. With this Jetfire now running, that makes 10 known 1963 Turbocharged Jetfires on the planet.
The way these were modified on the assembly line is similar to the COPO program. When a Jetfire was ordered, Oldsmobile would pull a F85 convertible body off the assembly line and weld a Buick hardtop to it (Olds wanted the Jetfire to be a true hardtop, and they did not make a hardtop F85/Cutlass at that time). Then, the special Turbo Rocket engine was fitted and other body modifications were done to accommodate that engine. A special rear axle was installed, and a special code "OX" transmission (if an automatic) was installed. I know its an RPO and not a true COPO, but a lot of modifications over the regular F85 were done to make it. So, my question is, what would this car be considered, a Musclecar, a Factory tuner car, or what? (I know it's not a 500hp Rat motor, but the car is 1000lbs lighter then a Camaro).
