"I was thinking about just the pushrod side of the fulcrum which turns out to be in error. Turns out you can approximate the plunger travel by multiplying the TURNS * PITCH * (1+ RockerRatio). The exact form of the equation is very cumbersome and provides an answer that has no significant difference; i.e., the approximation is very accurate.
So, for a normal BBC rocker arm on a 7/16" stud, one turn would move the plunger down just under 0.080".
Formerly, multiplication and division are inverse operations, not forms of mathematics."
