Temp 200, rpm 750, oil pressure 48 lbs
Temp 205, rpm 6300 and held for a few seconds, oil pressure 62 lbs
I asked Joe why the difference in readings and he said because the dyno was running the engine through an oil cooler and it had an adjustable flow restrictor.
Needless to say I am now relieved.

Good to see your oil pressure is where it belongs. The explanation Joe gave you doesn't make any sense to me. Wouldn't that limit max oil pressure, not having it fall off with an RPM increase?
In regards to your extra quart. That was a good band aid for poor oil control with windage as your side effect. I wouldn't do it on this setup if it's a quality pan. Windage is BAD.
Needless to say, track test it and look when everything is HOT.
