With my old 302, I would run around 35-45 psi at idle and up to 65 or so at WOT. That was with the stock pump and same gauge that you have.
A good friend of mine has a high volume pump and runs in the 80's at WOT, but his idle is a little lower than what you were experiencing - somewhere around 50-55, I think. My 331 will have a Melling High Volume pump, so I can get back to you in a couple of weeks with my numbers, if that would help? Just let me know and I can email you. E
