Identify my cam

Sorry, no pics yet. I don't have accurate measurements yet either, but here's what I know:

Lift is considerably more than a stock cam, about .400. Intake and exhaust are about the same.

It has scrolled journals and is drilled for the cam breather.

The end is threaded 1/4-26, not 1/4-28.

The side of the left intake lobe is stamped "50"
The side of the left exhaust lobe is stamped "6000"
There are no other markings visible anywhere.

Does anyone have an idea what it might be?

sounds like a megacycle 5600. it also requires the radiused followers that you were asking about. it is a little hot for a stock compression 850.

Yeah it sounds like it could be a MegaCycle 560-00, but curiously MegaCycle claims their billet cams are tapped 1/4-28. Maybe an old Norris cam? (Megacycle bought Norris)
