Am I missing something?  How can a program possibly calculate duration and lobe position specs from nothing but base circle size and lobe lift?

I'm going to have to figure out how to mount my degree wheel to a 22R.   That would be the best way short of an actual cam grinding machine to get meaningful numbers.

Went on a 4-day camping trip last Thurs - Sun and it showed I still have work to do on the Xtra cab - the engine sounds like it has timing chain slap, it tried to overheat going up Snoqualmie Pass, and 5th gear started making noise.  If I'm going to do the timing chain, might as well get the degree wheel on there and see what it can tell me about the stock cam.
