OP. I have Ford Racing gauges. Im running 5w30 oil on a fresh motor with less than 5000 miles. Once the engine ( and oil) are at operating temperature, I get around 25 pounds at idle and 50-60 so at high rpm. Im sure your pressures are higher because of the thicker 50 weight oil.
When I was building drag car engines we didn't concern ourselves with achieving high pressures. Volume, was much more important. And Im sure the volume of the stock pump is more than adequate for street applications.
