Estimating Lash Pad Size


Recommended Posts

OK I have a 530 lift cam & currently using .260 " lash pads. Wipe pattern is pretty consistent across the board with roughly .120 " band on the pivot side (give or take) & a roll off on the valve side. I need thinner pads to centre the cam wipe.

 

Does anyone know what the difference in .010 " lash pad size translates to movement of wipe pattern? Was thinking of perhaps .250, .240 & .230 pads & rechecking the wipe pattern.  Is it a 1:1 ratio ; 1:5 ration or perhaps something else that requires a more complex formula?

 

FWIW I did try the stacked feeler gauge method but its a PITA with only having the stock lash pad to work from as a smaller pad. %&^&$#$ valve stem recess on the lash pad is a %(*^*().
