Default I need help to identify this cam.

It was in a ls1 short block I got. It's supposed to be a low 230@50 cam on a 112. Thanks for Any help.

The numbers on top are lobe part numbers. You can match them up in Comp's master lobe catalog for the duration and lift values. The HR 112 means it's a hydraulic roller and it was ground on a 112 LSA. Usually it would have another number after the 112 to show how much advance was ground in, like 112+4 would be 4 degrees advanced. This cam may have none.

Do other cam grinders have access to Comp lobes, or is this positively a Comp cam?

I doubt other grinders have access to Comp's lobes, but those are definitely Comp part numbers. Looks like it's going to be Xtreme RPM lobes with 232/236 @ .050" duration, .541/.544" valve lift, and a 112LSA as already established.
