John Dampf's 1970 GTO
(In His own Words)

Dave built this 550 HP 468 back in 03.

Fully rollerized pump gas combination, it runs 11.20's in Edmonton all day long in a 3580 lb GTO. A new IA2 combo is now in the works.
Marcel and Dave are great people to work with , they understand your needs and will respond to any issue in a professional and workman like manner. A pleasure to deal with!
