A follow up. This regarding the question I posed within post number 9 if maybe Harold Brookshire stated it backwards on the percentage of the opening and closing sides of his lobes. And if I interpreted it wrong.
I got a private message from a friend with his opinion on that......
"No I don't think Harold stated it backwards. What I think he meant/said: in the opening side takes about 45* of rotation to go from the adv duration lift point [ say, 0.006" ] to the 050 lift point; on the closing side, it takes longer, more rotation of the cam, 62*, because of the slower closing."
