Oil Pressure

My father has a 71 318 in a 70 Swinger. The package is much like mine, 97,000 miles on engine, Comp 260 cam, running Royal Purple 10w40 synthetic. My question is that at idle when warm/hot, it has 14-15 psi of pressure( this is in drive at 750 RPM), and when the revs come up to 2000, it rises to 43-45psi, and 48-49 psi at 2500 RPM when hot. At cold idle, it has 60 psi. I runs strong with plenty of power for its age, it will still boil the hides. It has no knocks or anything like that. The only thing it has, which is similar to my 318, is a very slight rocker click when it gets warm, probably a worn pushrod or rocker.Just wondered if these sound like decent, acceptable numbers. It doesnt bother me, just curious. My hardened plastic or nylon tube that runs to my Sunpro gauge is a little long, which could impeade flow to the gauge, i guess lowering the reading. Let me know what you think. He has always ran Napa Gold filters on it. Thanks.
