cam id

I believe the number on the end is a blank #. It means something to the manufacturer before it is ground into a finished cam. I have heard this anyway?
You will have to measure the cam. I have several mystery cams on the shelf I will have to measure someday. Never get around to it. Seems I always end up buying new.
I do know that mystery cams are cheap. Would be good for your budget engine. I would install it and see what it is.
What cam are you wanting? Solid. Hyd or roller? Lift?
