Hello to group, I'm new but I thought if anyone could help me, a hot rodder could. I'm trying to ID a cam I bought for my Harley. I was told it was a Crane Fireball 310 H but the cam has no identifying markings like an Andrews cam. I do have the box, but how do I find out exactly what I've got? Any help would GREATLY be appreciated!
I also bought a cam for the same Harley which has 01-092 numbers on the end. Here again NO manufacture mark so I don't know anything about this cam either. Any help on this one too would GREATLY be appreciated.

V blocks, a degree wheel and a DI are cheap options.

Yep, with unknowns or no numbers, the only way you will know what they are is to degree them out, just like you would degree them when installing them.
You reverse engineeer a cam card that way.

Or you can send it to someone with a Cam Doctor rotary scan tool and they'll measure it all out and provide the cam card.
Jones Cam Designs/Mike Jones is one place that will do it...like a $25-35 fee IIRC plus shipping. Harley might be cheaper since there are only 4 lobes and not 16.
