ok thanks for settin that straight for me...i think ill go with the 112 straight up

I think that the original poster needs to clarify between LSA and ICL. When you say "on a 112", some take that to mean on a 112 LSA. Others take that to mean on a 112 ICL (as TurboBerserker appears to have done). When talking about 4 degrees of ground in advance, there is a huge difference between these two.
My assumption was that you were speaking of a 112 LSA for both cams in the original post. If that is the case, there is no reason that the 220 cam in the OP should have loped harder than the 224. Other factors must be at play (engine size, tune, exhaust, etc.). |

My point was not to disagree with your opinion of the proper way to refer to a cam's specs. I was simply trying to point out that LSA and ICL are frequently confused and the OP needs to be more specific with his question if he expects to receive a definitive answer. FYI, people refer to cams by Intake Duration/Exhaust Duration, LSA, advance all the time. See post #2 below

https://www.performancetrucks.net/fo...d.php?t=435550 Yeah, I agree. LSA can't be advanced, but the ICL can. LSA is amount of the circle (in degrees) between the ICL and the ECL. Edit (removed info that was confusing or wrong) |
:lurk:

The cam in my truck is on a 112 lsa with 110 icl. Would that still be +2

Most off the shelf cams these days are +2 or +4 in the grind. |
[QUOTE=TurboBerserker;4232111]Yeah, I agree -- I do the dur + lsa all the time too, however, anything with a xyz+a does not refer to lsa, but ICL. Your example in post#2 is not on a 111 LSA if his sig is correct, it's a 113 LSA on a 111+2 ICL.
That is an assumption on your part. Many people, including the example from my previous post, list xyz+a as their LSA+advance. Judging by the nature of the original question, I wouldn't think that the OP even knew the difference between ICL and LSA. That is why I thought it prudent to determine which he was speaking of prior to offering a definitive answer. |
