Thread: How to tell if it is a aftermarket cam

Tweet

how can i tell if its aftermarket? i know it has .500 lift

Look at some of the symbols and numbers between the cam lobes. My Crower has CWC between the lobes and clearly stamped "CROWER" on the end. From what I understand some company's provide cam cores to others. So I'd have to think some of the markings would be generic and possibly easy to ID. An old Crane Fireball cam I have has CC or CCC as I remember also.

good enough for a decent street motor that can make a few runs down the track?

Oh, sorry G, I took it as he wanted to know with it still in the motor.

You would have to get a degree wheel, and pull a valve cover where number one cylinder is. Set up a dial indicator so you could check the valve opening and closing. You need to first find true TDC, by using a piston stop by removing the number 1 plug, so you could mark the balancer for true O (TDC). Then go through the opening and closing of the intake valve a couple of times, or until you get a repeat of the degrees that match. Mark them numbers down. Then, do the same for the exhaust valve. When your all finished, you can then figure the duration, over lap, and the total lift, plus at what degrees it inituallystarts.

LOL I think your right Denny. I thought he was trying to Id the type of cam make?
