Ok guys im new to the PI 4.6 world.... WTF are PI heads? and PI intake? The 97 GT im about to buy supposedly has a 99 head swap.......how can i tell if this is true? and just what the hell is PI lol?
monkie, i havne't seen too many non-pi heads even in the same realm as an LS1...in fact i've NEVER seen . Except maybe a supercharged one pushing more boost than you should on a stock engine.
