If it helps, our '545' cam is our most popular with our 5th gen camaro customers. Not only does it have a fantastic sound, but it lays down 470-480 rwhp on a dyno jet with an intake/good exhaust, and starts picking up power even below 3,000rpm...it feels amazing on the street. With heads it ends up around 500rwhp, and it also works great with a blower should you add a TVS2300 or something like that down the road.
I run it in my personal car if that tells you anything! Here's a build blog featuring one installed in a customer's car -
