Give us a call I'm pretty sure we can get you lined out. We offer a pretty wide variety of camshafts based on your goals, and even a full cnc port for the cylinder heads if you decide to port the heads while they are off. Typically LS7 engines in Z06 vettes go near 600rwhp with our heads/cam packages depending on camshaft selection & other mods!
Checkout the LS7S & LS7R camshafts we offer. I've made over 550rwhp with both camshafts in LS7 applications.
