cam specs dont match when degreed
People often get hung up on the “advance” or “retard” thing, and how it relates to the numbers.
If you remember what the c/l numbers are referring to, it should keep you straight.
It can sometimes be easier to think of it in terms of direction.
You are moving the cam clockwise or counter-clockwise relative to the crank.
Whichever direction you move one lobe...... the other goes with it.
Look at the(typical) degree wheel....... if you moved the cam from an int c/l of 106...... clockwise 3*, the new c/l is 103.
If the ex c/l was 114 when the intake c/l 106, and you moved the cam 3* clockwise.......if you look on the exhaust side of the tdc mark of the wheel........what is 3* clockwise on the degree wheel from 114?(it’s 117).
