Ok, let me try again, since I proved that the cam is ground as the manufacturer said it is, LSA = 113.5, Intake c/l = 112, Exhaust c/l = 115 and the LSA is determined mathematically only?

Now, I use the Intake c/l @ 112 and add 1.5 degrees built into the Cam from the Melling factory, sold by Butler, together = 113.5 what? is this the new Intake c/l that just happens to be the same as the LSA?

I have 113.5 whatever?

The Cam is advanced now @ 4 Cam degrees.

8 degrees advance @ Crank.

1.5 degrees, added into the Cam at the factory. 112 Intake c/l + 1.5 advance = 113.5 what?

Given the same information that I have, can you finish the equation, in Cam degrees, please?

I believe I am at: (1.5 + 4 = 5.5 advanced), 113.5 - 5.5 = 108 degrees new Cam timing. I used the 4th notch at the Crank here.

My original target advance was: (1.5 + 3 = 4.5 advanced),
113.5 - 4.5 = 109 degrees new Cam timing. I used the 3rd notch at the Crank here.

I believe one is as good as the other because I won't be testing to see at the track.
