overheating/high oil pressure

Guess you don't have a restricted exhaust problem! Get some good numbers together and post them. Lot of sharp guys on this site to help you with troubleshooting.

It's my first post but somebody is on to the right lead, because you instrument cluster voltage regulator is on the fritz, happens in my 84 from time to time. The regulator is changing voltage causing both the oil and temp gauges to read higher then normal, I bet if you pay attention I bet your fuel gauge reads higher as well. Start with the simple things first the regulators are cheap and are known to go bad.

Said a few times already, but add another vote to electrical problems.

Get some real gauges on there to verify everything is right mechanically, then go from there with fixing the stock gauges.

The temp gauge is messed up for sure but its still running hotter than it should be

Temp haulage does this as soon as the truck starts. Oil stays abou this unless I'm Dickinn off and revvin it up. Gas gauge is a little iffy. Speedo gauge is off for sure. I was going about 25 and it said 10. Then was goin about 10 and it wa at 0

Oil gauge stays about here

My 77 reads that high on initial start and sometimes for about 20 mins.

The owners manual says as long as your in the normal band theres no need for concern.

If you speedo is that far outta wack thaus why you dont think itll do over 50

That temp gauge is pegged and its due to the cluster regulator beat the dash lightly with a fist and sometimes they go back to normal.
Or your sender shorted out.
