Stock oil pan and HV oil pump?

Think about it this way, a stock pan takes 5 qts, say close to 1 qt is in the filter at any given time and prob at least 1 more qt floating around the engine. That leaves approx. 3 qts in the pan, now you decide to run it through the gears. Would you feel safe doing it with 3 qts in the pan and a oil pump sucking like mad? Most engines don't need a HV pump and a lot of racers have stopped running them on a motor that's assembled properly, extra drag. The windage tray wont help to keep the pan from sucking dry, but is good to run. Just my 2 cents
