Okay, with my LT4 HOT cam, the car pulls good till about 5000 or so, then it runs out of breath because my TPI is stock. I am however getting a new Accel Intake base in the current GP, do you guys think that will help my car pull till 5500+? Also, I have new valve springs from TPIS, so I will be able to safely rev the engine over the 5500 red line and be okay, right?

Sounds good to me. Did you check for coil bind and piston-to-valve clearence when you put the cam in? My engine pulls to 5500 and a little bit beyond with the LT4 HOT cam and TPIS intake/runners. I've also got an AFR Hydra-Rev kit.

I didn't check for those things as I didn't know I was supposed to or how do even do it. Reguardless, the car runs great now and I know there is plenty of piston to valve clearance, although I have no exact numbers. Anyway, the car should breathe pretty high I hope!

Did your car actually get faster with stock heads and that cam? Somehow, I doubt it. I have seen that cam slow down cars with more mods then you have.
