both of those techniques work just fine IF you have a stock cam. What if you don't or don't know for sure?

I was just offering a method that works on anything. Any cam, any motor, no manual, no assumptions.

A lot of guys are dealing with 30, 40 or 50 year old motors. Most of them have been rebuilt a time or two and it's only "hear say" what's in them. The cams are almost always upgraded.
