Rhoads V-Pro Street lifters and push rod length procedure

[MattK2]

A set of Rhoads V-Pro Street lifters are going on a 455 with a Crane 041.  Adjustable Crowers also new.  I've read the procedure on how to setup the Rhoads lifters, but nothing about determining new push rod length.  It's odd that Rhoads assumes that your push rods are correct length and doesn't even bring it up on the published instructions on the website.  Not the best technical writing, but it's OK.

My guess:

Set the rocker nut down half the lift with the feeler gauge installed to account for the lash you'll use to reduce duration.  Install push road with the cup seated in the bottom of the lifter.  What else?  Or am I way off base?

Nowhere in those docs is a procedure on how to determine push rod length using mid lift theory. I could guess by looking at the way the lifter setup is supposed to be, but I’m not an engine builder.

Rhoads answered my question.  Set adjustable rocker to desired position using mid lift method valve closed.   Install checker rod. Extend push rod so plunger bottoms out in lifter but doesn’t lift the valve. Add about 0.020”. Yeah he wrote “about”.  Do this before oiling lifters so they compress easy. That’s it.
