No, you are wrong & for the umpteenth time LSA, LCA [ & LDA ] are the same thing, just different words used. Like calling a lifter a tappet....
Neither of the three have anything to do with the alignment of the cam to the crank.
If the cam has a 108 LSA [ or LCA or LDA ], it still has that angle sitting on a table & nowhere near a crank. It is in cam degrees & is ground into the cam for the cams in this thread.
LCA cannot be changed without having the cam re-ground.
You are confusing ICL [ int centre line ] with LCA. ICL is measured in crank degrees. ICL can be changed by moving the cam relative to the crank using multi slot sprockets etc. If you add the ICL to the ECL & divide by two, you get the LSA.

I'll have to re educate all the Cam Grinders I know:rolleyes:
I guess you just can't be told, can you. The reason LSA is spelt different to LCA is because they mean two different things.
LSA refers to the angle between two lobes, LCA is a reference to only one lobe.
Separation.....Center... use a Dictionary..
ILCA, ELCA, ILCD, ELCD... See I can make it even muddier and more of a mess.
I see David has a new book out, but somehow I think you already have a copy.
