You can do a search on this forum. Nutshell the ported stock stuff works and works well to a point. The general rule of thumb is with cam, especially a large cam, it is better to go to MSD and 95TB (ported or not).

I was merely pointing out that cam and heads have been shown to add upto 80 engine HP, even with stock IM,TB and header / manifold. TSP itself broke 600 engine HP with a stock engine + ported head and their beta VVT cam.

So it comes to a money issue, go with cam and ported heads and save the $1600 on the MSD and 95mm (which can be added later). Same goes to CAI, I'd just cut the box and maybe run a green filter save the $400 for cam and heads.

If this is NOT a money issue, King is correct that the general rule of thumb and get the MSD and 95 both ported and never look back. The stock intake is not only limited it has two different runner lenghts. Hope GM comes out with a LT2 version of their manifold that would directly bolt on to the Camaro just like the LS1 to LS2 / LS6 intake upgrades.

Okay awesome, this was the answer I was looking for, thank you very much!
