537 hp with bolt-ons!
A big thanks to both you guys. And Kurt had his work cut out for him with these Stainless Works headers. Thanks for your hard work!
Has GM done something to the newer Z06s since the valve guide problem so they now apparently make more power? I have not read where any of the 06-09 have made this much power with factory heads/cam.
It might make good mph at the track but I have always raced automatics and not sure I can get a decent 60' with this manual and with this tall first gear. This car needs at least a 3.73 gear and a 3.90 even better.
I was wondering about the valve guide issue also. What is the guide material made of in a stock ls7?
