Bakerlite,
You cannot even read your own chart in post #92.
It says: 'centerline, degrees, intake profile, 102. That is referring to the ICL, Intake Center Line, not Lobe Center Angle. Which is 106* for that cam; which is the same as Lobe Separation Angle. Get it? Apparently not, so read on..
[1] Cam grinder Sig Erson says this in his catalog: 'Lobe center line angle, or lobe centers, is the angle between the theoretical center line of the exh & int lobe'.
[2] Page 8 of my Comp Cams catalog:'..the difference between intake c'line & LSA. These two terms are often confused. Although they have similar names, they are different. LSA is the number of degrees separating the peak lift points of the exh & int lobe.
[3] The Hotrod camshaft book, p 116.' The angular measurement from the c'line of of an intake valve lobe to the centerline of the corresponding exh valve lobe is called the Lobe Displacement Angle'
[4] Page 4 of the same book: ' The lobe separation angle, also known as lobe center line displacement angle.
LSA, LCA, LDA all the same thing.
Maybe you can post the name of the cam grinders you know in post 89 so that I make sure I NEVER USE them.
They are dopes like you.
If anybody wants copies of the above, PM an email address.
