Checking Pushrod Length
« on: November 17, 2012 - 01:36:46 PM »
I'm trying to check my pushrod length using a Comp ajdustable checker,  on a stock  440  hydraulic set up as you'd expect the lifter compresses and there's no way to get a complete lift to make your mark.   do I need a solid lifter or something or is what I'm getting close enough?

As I have it determined now my rocker sits about 1/3 of the way across the stem from the intake side and my pattern is centered. what pattern I can get with a lifter compressing anyway.

 I can't figure out what you are asking really , the pushrod needs to have approx .020 preload int he hyd lifter with the valve closed on the back side / low point of the cam lobe

A lash cap is great for increasing the surface area
