427w, Morel 5323, street car, Ed's cam, max 6000 RPM.  I have lost all my information referencing the lifter preload.  I'm using 7/16-20 stud mount rockers.  What is the proper preload on these?

By this, they call for about 1/2 a turn.

I'm sure it would be fine, it just sounds like a lot to me. Personally, I typically do 1/8-1/4 turn and then "set" the setscrew of the polylock with an additional 1/8 turn of the nut and setscrew together.

Thank you.  The nut moves .050 per full revolution, but the pushrod end of the rocker arm moves more than the nut does due to rocker ratio.  1.6 rockers.  Using a little trig, came up with .080" preload per full turn of the nut.  1/2 of that is .040.  So I did about 1/4, tightened the jam nut and cinched the adjusting nut down a hair more, then did the other 15 the exact same way.  We shall see.  Dyno next Monday.
