I talked to a tech at summit and he said that the numbers listed are just the base numbers and the cam would pull to 5200 no problem.

I'd look for a little more lift and duration.

This is the cam I am currently running but I was told by Summit technical services that the lobe seperation was too tight and it wasn't computer compatable. The Tpi cars like an LSA of 110-114?

Is there a problem with how the engine runs now?

That Isky cam looks to be pretty mild to me, and I'd think would be better than the stock cam if used with stock heads.

TPI does like LSA of 110-114

The engine runs fine, but my emissions HC and CO counts were high so I am trying to figure the problem out.

"Comp Cams has a computer-friendly grind that works well with the TPI and MAF. Call them and ask about the 260AH-14 grind in your application. It specs at .444"/.444", 212°/218°, and 114° LSA."
268AH-14 looks like a good choice for a non-stock setup.
