No, I'm saying its eligible as are all other cars except open wheel. You won't win Nationals, but a well modded Z28 will find someone to race with at a regional race. This class attracts a wide variety of cars, and where you finish depends on who shows up.
Note that I never said anything...
The point is you said that “the Z28 is not permitted in NASA”, and that you “can’t race the car ANYWHERE”. On those points you’re 100% wrong, so you need to stop making those claims if you want to maintain any credibility at all. The fact is that car can run in ST or SU with nothing more...
