Just something to ponder and engineers please verify my math....diameter of of the cam base circle is about 28.77mm and if I remember my high school math that makes the circumference 90mm....which means the one degree on the camshaft is 1/4mm?

360 degrees in a 90mm Circle would mean 1 degree=.25MM correct? I guess the point I am making is that it does not take much to move the cam a few degrees in reference to the crank.....

I am doing a novice write up on cam timinig....

This camdegree setup is genius; uses the plug hole as a stand and two dial gauges split off...

"Base circle", in my mind anyway, refers to the lobe(s). That measurement threw me before I realized you were referring to the cam journal. A 28.77mm base circle would = one heck of a re-grind!
