I can kinda help. He is actually right in my development where I live. He has a nice big house with a four car garage he restores vettes out of. A guy I work with had him install a supercharger, gull wing doors etc on his Z06, and the thing runs!. I've seen a few Vette's out that he has worked on and restored and they look really awesome, and I've heard he has sold a few at Barret-Jackson.
