You wouldn’t be wrong in that miss on the cam and it’s hard to crutch the rest of the combo to make it happy.

What’s the actual part number of the Comp cam? It’s probably on a 110 LSA. and they want it in on a 106 Intake Center Line.

Just so you know, the Lobe Separation angle is the actual centerline of the intake and exhaust lobes of the same cylinder. It is fixed when the cam is ground and can’t be changed on a single cam application.

Intake Center Line is where the cam is degreed. That means if you install a 110 LSA cam on a 106 ICL you have timed the cam so that maximum intake valve lift occurs at 106 degrees After Top Dead Center. It also means the cam is installed 4 degrees advanced. If you installed that same cam on a 110 ICL it would be installed “straight up” or split overlap. Should you desire, you could install that cam on a 114 ICL and then it would be r degrees retarded.

If you look at the numbers and what you are doing you’ll see that advancing the cam is actually doing that very thing. It is advancing the timing events. Retarding the cam means just that. You are retarding the timing events...opening the intake valve later as well as all the other events occur later.
