Eric's cam challenge
I would guess all the specs are pretty important, I do get what Newbomb Turk is saying as soon as the valve seal is broken obviously **** is happening, but it seems like @ 50 seems to describe a little more if you were gonna go by only one @ spec how it's gonna react in your car eg.. A 220° can be all over the map in advertised duration. I prefer when cam companies give both and wish they also gave .200 specs also.
