Cam ID help

In addition to the purple paint, MP cams were not parkerized(the black coating on the lobes).

I’ve never seen a Comp without their numbers on it.

Most “name brand” cams(Isky, Crower, Lunati, Howard’s, etc) will have their brand on them.

No name cams of the past were usually “white box specials”, where the reseller takes it out of the plain white box, and puts it in their own branded box.
Many of those were ground at Camshaft Machine Co. in Michigan.

You should measure few lobes...... intake and exhaust..... to see if it’s a dual pattern or not.
