I want to swap my cams out but im not too sure which one i want....i have SLP LM2's, BBK o/r X-pipe, and BBK LT headers(1 5/8 primaries, 2 1/2 back), BBK Twin 65mm Throttle Body, and K&N. I looked at the Comp Cams XE-R Stage 2 as idle doesnt really matter to me. Would this cam unleash the horsepower im looking for? or would Ford GT or FR500 Cams work better. Im looking to make as much Horsepower on the stock Longblock as possible. The cams i want are Xtreme XE-R Series, XE270BH-114.......and i was wanting to know about how much power i could get from these cams? and would it be worth it in the long run? as in want to go N/A anyway. And if i am upgrading to a rough idling cam like this, what problems could i encounter because of that?
