LA Roller block cam options

I've thought about them before, and not just "from" this board. I'm sure I'll be calling them in a few days. I need to get busy (the 318 is out of course) and make a profile of that cam. It doesn't have to be that very cam, of course. But I'd like to know what it "is."

And of course not knowing what it "is" I've never degreed it, just tossed it in, "straight up."
