Have you tried contacting Crane? A few months ago I went through the same thing, and after contacting them, they sent me the spec sheet for the cams. I can only attest to what's on the cams I have, but there should be a sequence of letters and numbers "etched" towards the cam gear end of the cam that will identify the grind, and at the opposite end there will be a number "stamped" that will identify the platform they're used for.
