Lifter Preload Help!!!!
#22
The best way to get the proper preload on these lifters, is to install the lifter as normal, then drop in an adjustable pushrod length checker, then, install your rocker and trq down to 22ftlbs. Then adjust the pushrod till you have zero lash at the rocker base, remove, then measure. Then add .030 to that measurement. That got me to .035 preload, so its a good method.

EDIT: forgot to mention that you have to make sure you're on the base circle of the cam lobe you're measuring on...

They made you an extra special set of variable length pushrods. I bet you feel really special.

Hope this explains it, but it makes sense that if you tighten the rocker down the pushrod will move more than the rocker pivot point.
