Are these numbers the Part Number? Or maybe the grind number?

The lobes look like they might have a bit more duration and lift than stock, IMHO.

The shape of the lobes appear to me as if the cam may be a roller cam, probably a hydraulic roller. The only thing I could come close on was the Crane series roller hydraulic cams. They all begin with the numbers "289". So you may have an earlier version of what they offer now. Might want to contact them just to ask, they may know, or will tell you it is not one of theirs.
