I have owned the car since 1998 and decided to build it the way I wanted it, there is nothing original, non matching numbers, this has a 350 HP 350 4 bolt with aluminum heads and a small cam,Transmission is a turbo 350 with a firm shift kit, factory exhaust ( Hollowed out Converter . All new interior, Body was striped down to the seam lines and blocked and painted, frame was perfect, no rust or repairs, all GM door rubbers, T TOP and window seals. Inside the door jams look just as good as the outside, Power doors, windows locks, I had some 82 parts so I used the back window for that easy access. All the brakes have been changed.. The car has been garaged since 98 and has seen no rain at all..Restoration was just completed 2017.
