The pump is not your problem - you need a windage tray. The oil clings to the rotating crank. The faster it turns the more oil clings to it. When you put a windage tray on it you scrape that oil off the crank and put it back in the pan where you need it. A high volume engine doesn't push any more oil into your engine than a stock punp will because the pressure will only push a given amount of oil through the clearances of your engine. The extra capacity is dumped into the pan through the relief valve on the pump. It does ensure that there is always enough oil to lubricate that last rod bearing in the oiling circuit. It also maintains pressure as clearances grow. If you plan on running your engine for 150000 to 200000 miles it is good insurance. I too have always run high volume pumps with no problems - even to 6000 rpms.
