Difference between lobe lift and pushrod lift

BJR, The small block mopar camshaft does not transfer all of it's motion to the pushrod end of the rocker. I am not speaking of pushrod deflection, rocker arm flection, hyd. lifters (plungers), solid camshafts (lash), inaccurate rocker ratio's or cams ground incorrectly. We all know as you have correctly stated, these things contribute to a loss of lift on thier own. That's a given. Because of the poor valve train geometry in the small block mopar, mainly due to the lifter body and the pushrod not being in plain with each other...there is a loss of lift (motion), from the camshaft to the pushrod end of rocker arm. As correctly stated by MRMoparTech, "one of the reasons we choose the wrong components". As for the 'ranting'..it's ok..no need to apologize...I do it too. Terry.
