cam lift lost

Thanks for the lesson 70.
I've always just used "about .020" in less than .500 (advertised lift), and "about .028" in bigger than .500. That came about from measuring a few a long time ago. Also, I think the height of the lifter affects it. The taller the lifter, the shorter the pushrod, and sharper the angle. The higher the rocker ratio, the closer to the shaft centerline the pushrod socket is, and the sharper the angle.
It's been decades since trig for me... But I seem to remember something about that...lol
