I am on both, I used to restore 60's GTO's and now only do new cars, I work in a repair facility and have done many a maggie, and heads & cam cars. We do mostly fleet trucks, but are into speed. Next up 418cid 6.2L na motor for my FRC shooting for 650 hp in progress, and a maggie for the 04 gto next year.

thanks
