Rocker arm recommendations?

B3,
'Ratio is not dependent on the valve side only'. Of course not, never said it was. I said in post #40, point [3] there is the valve side ratio & the p'rod side ratio.

Your drawing above depicts what I was saying [ & Smokey ] about the ratio not being constant on the valve side. You show the figure of 1.477" at max lift as I presume the lever arm length. If you are using that to calculate the ratio [ valve side ] @ max lift, it is incorrect. At max lift, the lever arm, & corresponding ratio, is greater than the nominal 1.500" because the lever arm is measured from the point of contact of the roller on the valve tip to the fulcrum centre. It might be 1.520", as an example.
