Cam \"IDs\" maybe aftermarket?

I got these cams with a oilcooled gsxr 1100 big valve head i bought. Not sure if there Megacycle or other brand but here are the stamped #'s 21776 7 95
I had another set of cams awhile back that had #'s like these also.
By the way, #s are stamped on the ends of the cams, Int-ext cams are the same #.
How do i check the lift on these cams?

Re: Cam \"IDs\" maybe aftermarket?

Both cams have the same number on them? Weird. Check with the cross reference here to see if that part # is a valid Suzuki number or not.

Measuring the cams is easy if you have a micrometer big enough. Just measure the long length of the cam lobe and subtract the distance from centerline to the journal. Thats the measurement calle "lift"
