The whole reason I'm doing this is because I just did the conversion from idiot lights to gauge cluster. My oil pressure is pegged at high when the truck is running. I need to verify what my actual PSI is, owners manual for my GM crate engine claims 40 PSI at 2000 RPM. I'm idling at 600 RPM and its buried past H.
It's a brand new cluster with all brand new gauges.
It's the only gauge now that isn't working correctly.

Stock gauges are 60psi so center would be 30. Trying another stock gauge would tell you whether your replacement unit is screwy or not, or if something else was causing it..... My '68 with a stock 327 pegs the needle when it is cold, so does the '72 Dually with the new GM crate engine. Doing it that way would keep you from having to cut up your new oil line.
