Did the search. I always search. I even read the first few lines of old threads on google. Only found flathead info

divide the stroke by 360 then consider dwell time at top and bottom of stroke. Al Nunely had a chart on the old bobs that was pretty accurate, but remember not all cranks are created equal.
