Yup, that's usually what FAQ's and archives are for. Otherwise
you end up repeating the same stuff over and over again.

True for any Holley (or other carb) on any engine. If the jetting,
PVCR's, pump, power valve are right out of the box for your
engine it's only by coincidence. The required carb parts are a
function of the particular engine combination (cam, intake, headers,
etc.).

Yup, I mention that in another post. Don't forget the power
valve and PVCR's.

I usually leave the accelerator pump tuning until last and
then set it pump as little gas as possible.

Nah, you should be able to set the choke plate any place you
want it.
