Anyone got a set of 93-95 cams lying around? Wondering if you can measure the base circle; which should be 1.29-1.3; then measure the overall height. Found something funky on the ones I have

Lee,
Some measurements from some data samples I have made. New 93~95 Cams, B/C: 1.299~1.304, O/A: 1.688~1.692 These dimensions are the same as 90~92 cams

Well, maybe they never were ground to stock lift. Entirely possible they were machined & ground from forged blanks with the stock B/C with higher lift.
There are quite a few of those around. I have 4 of them in my Zee. SGC Stage I cams have 0.415" lift, close to what you are describing.
