Cam degreeing help me understand!

Can I ask a stupid question??? When there is an advance ground in to a cam, that will be the measurement at the lobe. Correct? Anotherwords....my cam card states 106 intake and 114 exhaust. That should be my actual measurements. No? I guess I am not understanding the "ground in". Is my cam 110 with 4 degrees advance ground in giving me 106? What about the exhaust lobe?
Does advance get ground in there as well? Also, when a cam is advanced or retarded via crank gear or offset cam key, the exhaust should move the same amount of advance as intake. Correct?

Here is the truth about ground in “advance”. Any advance ground into the cam is for the sole purpose of hoping beyond all hope that if you line it up dot to dot it will be installed at the correct ICL. Sooooooo, if you cam is on a 110 LSA and Ken wants it in at a 106 ICL and IF he ground 4 degrees advance in it, then you can theoretically line up the dots and it would be at a 106 ICL.

And just as often as not, lining up the dots doesn't produce what the cam card calls for. Which is why degreeing the cam is the ONLY away to know where it’s installed.

You are doing everything right. Something is just giving you grief.
