Only way you'll ever pump the pan dry is if it's pumped into the heads! At any rpm, this is the only way that can happen.
Too much oil will get pulled up by the crank and airate the oil, super heat the oil around the crank, and eventually starve the pump with cavitation.
You really have to pour a pan and check them for how much they'll hold under the baffling, then add the proper amount back for the oil galleys and filter. Try pouring a 7Qt pan and see how much is actually held in the sump...you'll be amazed!!
