Stock Hydraulic Lifter Preload Spec?

1-1/8" turn on a 3/8-24 adjuster would only give you .047"; about half of what that cam card calls for. Also, I'm guessing that spec is for Hughes lifters. I need the range for factory replacement lifters. Thanks for the input though.
I agree; however, taking into account the rocker ratio (1.6 for me) that gives 0.075" ... I may have been a bit off on the number of turns ... maybe it was 1 1/4 which wouldresult in ).083" lash at the valve.

The cam card states for "Standard lifter pre-load" so I guess that's a bit subjective.
