Traded in my 03 Anniversary Vette and got a 05 Red GTO A4, JUST LOVE IT!!, But I had my Vette running 11.50s and want to get there in a hurry. I am going to buy the aluminum SLP402 and cam it with 232/234 598 @ 114 ThunderRacing cam. I've got an Art Carr 3000 Stall converter, I want a near stock idle and want to hit 11.50s or better on motor what is you alls take on this effort, I'm new to GTO's and don't know how they take to modifications, my vette did it with a cam only, but a rough idle. I appreciate any advice on the topic.
