Ok, I measured up the cams tonight as best I could. Put them both in the lathe and setup the dial gauge. I could only measure lift.

The cam marked 921 measured 6.75mm lift on all four lobes, x1.39 = 9.3825mm or 0.3693"

The cam marked 630 measured 7.64 lift or near enough on all the lobes, x1.39 = 10.6196mm or 0.4180"

Is lift alone enough to identify these two? Is there a list of specs somewhere?
