Advancing/ Retarding Camshaft

I don't know how big the cam is - someone rebuilt the motor and put some sort of hydraulic cam in there. As for the timing I counted the number of teeth on the big
cam gear and divided it by 360 - came out each tooth was close to 8 degrees. For
some reason thing there were 47 teeth on cam gear(360/47=7.**) I was hoping to see some numbers on the front of the cam when I had it apart but didn't see anything.
