If it were me, I'd find a good Plain Jane body, paint it to my liking, and stuff the drivetrain into it and have myself a sleeper.
The Camaro this drivetrain came from is long gone, only value would be for date correct build if one were going to build a clone,
and then the devalue of a cloned Z/28. Might be more honest presenting it as a PJ with Z/28 internals and enjoy the cruise with the car.
