zr1 cam compared to patg 218-238
could anyone tell me about how much hp and tq if any would be gained switching from the stock zr1 cam 211-230 to a patg 218-238 119+3LXL. this would be used with a whipple on a 2010 camaro A6. i made 640-540 with the zr1 cam already. i have considered the gt9 but to many people say it's hard on valvetrain? although there seems to be plenty of caddy guys running it.
