Alls been said! :P The reason for running a little less oil is to get the oil away from the crank. A good windage tray with a built in scraper will also assist in keeping oil away from the crank. With a deep pan with added capacity you can do this. I personally run 6 1/2 qts in a 8 qt Pro Stock Enginnering pan along with a Canton windage tray with scraper and a 1 1/2 quart capacity accumulator and low pressure switch. The trap doors, baffles and fins in the pan are for oil control to get the oil back to the sump and to keep it there during acceleration and de-celeration. An accumulator is always good insurance and may save your engine if something goes wrong by keeping things lubed for that extra time that it may take you to notice a problem. I would also install a low pressure switch on the ignition on any race motor for added protection. George
