I really loved my old school GK C1M-308R. I went from the 140 cam to this in my LT-1 and it was noticeably stronger in the mid range. It was hard on the valvetrain though. It also barely had enough vacuum for the brakes but man what a rush at 3500. This was with stock heads and the dual plane manifold. 4:10 gears and the M-21.
