Mike, EH's comments are pertinate. You own a powerful 43-year-old, heavily modified performance sportscar; things do & will go wrong. When the pump comes out, check the internal bore and gearotors for deep scratches that will reduce oil pressure. As he said, new Melling pumps are cheap; I suggest a std pump. The whole exercise should take a Saturday afternoon. Then take the thing out and beat on it! Better you ferret out weak spots now than 60 miles out in the desert.
