I bought 1987 #17 a few years ago for $13K. It was in rough shape; rebuilt the turbos, all of the lines were leaking, trans leaking. Its a pain in the *** to work on and they are sensitive to changes.

I do not think my experience is typical, but tuning with mods using the Callaway system requires some expertise. I have a prototype intake on mine, I also have the last copy of the sledgehammer cam made by Dave Generous(not installed) along with a wonderbar(not installed).

If you have means, I would say go for it. I would expect to spend a few K on repairs.

They drive like an L98, and power comes on differently than a LT-5....its like something pushes the car from behind
