very simple small cam and stock 862 heads atop a ls1. 85mm tb, long tubes, unfinished tune with 273s and some spare parts in the trunk (toolbox, and another 10 bolt rear end complete). 4l60 with a converter that shudders hard in od so I drive it in 3rd. that said, car isn't running in tip top shape and has more to give.
This is the Black Z28 with the 5.7 not the 6.0
