Dwayne, do you mean checking for lift at the retainer with everything assembled to run? I'm still learning the lingo over here lol. We did check it and it was pretty close IIRC, I'll have to dig in my notes.
Yes, lift at the valve with full spring load and zero lash, divided by the actual lobe lift.
I realize this is actually checking the "system" net ratio, since there is deflection of other components besides the rockers, but IMO, unless the pushrods are seriously undersized the majority of the deflection will be in the rocker.
Just curious how rigid those rockers are, and whether any additional ratio was "built in" so the net loaded ratio was close to what they are supposed to be.
Some brands seem to have this, some don't.
