The 114 is overlap.. That will work fine on a FI set up.... Yet still have a choppier idle then stock..

Got it. It just chop light or just hard chop idle? I need to know just add 114 or different one 114 +?(for numbwe of LSA) Because I read some people who running with 110+2 or something like that. I wonder about 114

+# is the amount of advance built into the cam. It brings the powerband down.

I'd go with the TSP220 or 224 with the 5.3

I think it will hurt since I do tow sometimes. Thats why. 212/218 will be ok. But Im confuse on LSA Im try to keep search on LSA there is too many number I can't figure. I would like to know why LSA (lope Separtion) Like engine may picky if I go wrong number of lsa.

Sorry, I have to correct you, 114 is not overlap, but is rather the "LSA" or the angle between the peaks (centerlines) of the Exhaust and Intake cam lobes. Overlap is measured on a graph when you take the lift values of a cam lobe and plot them over degrees of rotation. When overlap in a cam exists you will see the exhaust lobe in the act of closing (but not closed all the way) and the intake lobe will start opening. The degrees of overlap are measured when this condition exists (when the intake lobe opens before the exhaust lobe is closed) from the point at which the intake lobe opens to when the exhaust lobe finally closes. LSA is just the angle between the centerlines of the two camshaft lobes.

Not disputing that the cam will work for F.I. for clarification, as I have not personally tested that cam nor have I seen it's geometry.

Just tell me which cam should I go for na/later boost. Remember I do tow sometimes. So 212/218 is good enough to go? All I need to know what number of LSA will be ok for na/later boost. Or I have to pick ONE LSA which Im running na or boost? JUst tell me which lsa I just ahead get it simple without ask to much. Just like to have sounds beaufail!
