Gunner, I believe a '10 Camaro comparo was attempted on that one. But Ford already has the 'Stang and they are reviving the 5.0 GT, so it would be wasted effort. Besides, the GR-1 is waaaay too sexier for that...could be easily postured in the Z06/Viper arena. In this economy though, no one is going to touch that thin market.
Which brings us back to the only shop that could actually pull it off in kit or turn-key minus form...
