Can someone identify what this cam grind is please?

I bought this cam used, the lobes look good but it didn't come with a cam spec card. I've tried looking but I'm not finding any info that matches what I have. I'm probably looking in the wrong place, but anyway, I know someone on here will be able to spill out the specs for me,so if you can, thank you very much.

CC equals Comp Cams, look up the lobes or degree it at .050 lobe lift to see what grind it is

1737 lobe
320/287 .515 lobe lift

1871
330/292 .500 lobe lift

Thanx
