I have the PDF I can email to anyone who wants to print it. And no, you don't mark cranks and blocks, you simply do the math.
Here is a photo when I was indexing an unknown cam in a Raptor I. In this instance, I was getting crank angle at .050 lift, because in most cases, that is the number used by the grinders. That number will indicate how your cam lobe centers are set up, as well as ramp slopes, and of course max lift, which seems to be what everyone focuses on, because they're too lazy to put a degree wheel on. But hey, that sells cams, right?
Shoot me a PM with your email address, and I'll send you a PDF file you can print of a degree wheel.
