Have 2 GP's
99 Grand Prix GTP, L32 Swap, TOG's, SIX cam is my 2d E85 car.
98 Grand Prix GTP Turbo, ST2, PT61, FMIC is my 4d DD

Dan, I don't own them...thinking about buying them.
Nick, Not planning on swapping out the cam anytime soon. Have a full Stattama kit on the shelf with ST4 or ST5 cam going in it...if I pull the trigger on the bigger turbo build.
