Mike, Most engines are set to provide 15 psi ( 1 atmosphere ) every 1,000 rpm up to about a normal industry wide bled off at 75 psi about 5k rpm. Your hot idled oil psi seems higher than normal. Which is ok if you have a high oil volume instead of a higher pressure unit. Oil grades, brands, weights and synthetic or not truly do not make a difference in psi/rpms.

Received the mechanical gauge from Mike Drew today (thanks Mike). Put it on and started the motor, and it reads 60 lbs. at start and warm up at 1500 RPM's, not much less at idle (~900 when the choke lets go(, and only a little more when I rev. That doesn't seem right. I would expect it to drop pretty low at idle.
Thoughts?

Know it well, the zip code is 78154. It's right outside San Antonio and next to Randolph AFB, where I was stationed for most of my Air Force Reserve career. About 60 miles from my house in Austin. I'm sure Michael Frazier knows him. Sent from my iPhone

Actually in a town called Schertz, not sure how close that is to you. Zip is 87154.

That wasn't me, Mike. If there's another Richard in Austin with a Pantera, I'd like to meet him!
Did you attend the Rally two years ago put on by Space City Panteras?

Thanks Richard
Are you the same Richard in Texas who just bought my firewall cover?

Mike, I obviously can't tell what your problem is from here, but mine did
that for a while. When I tapped on the glass sometimes it would start
working again, sometimes it wouldn't. Then it stopped and has been normal
for a while. I think it's obviously the gauge.

I'm trying to figure out why I'm getting a pegged reading on my oil
pressure gauge. It will show normal pressure as the car starts, but
soon after pegs to the right and stays there. Everything runs fine
otherwise. I've swapped out the pressure sender, NAPA OP6091, and
it's still pegging, so I'm suspecting the gauge. Anything else I could
check?
Thanks
