I second the motion that you consider the TR224 on a 112. I put in Texas Speed's cam with the same specs (more lift, though) in my C5 with their 5.3 liter heads. It gives a really nice, broad torque curve, and I'm at 410whp, which is about 93whp above my baseline with CAI. With an F-body, you'd probably hit a few more ponies, I think... Even cam-only, a lot of guys are getting high 300's with that cam. It lopes some, but isn't obnoxious (especially if your catback is mild). Good luck!
