Well Bart that's a pretty firm statement but the reality is every car/motor is different. It would be great to say if you have this then that should be but since I'm dealing with a cammed up 462ci with 10.7:1CR at about 520hp with full length headers and a tiny engine compartment in stop and go traffic on a day when it's 100+ degrees outside...all absolutes kind of go out of the window. Pontiac really didn't design for this so factory stuff just doesn't seem to cut it anymore. Time to get creative with some out of the box thinking.
