1999 2 Door Tahoe 60psi on start up...

[alphasurf]

hi all I am proud to own a 1999 Chevy Tahoe 2 Door. I recently bought it from 2nd owner. On start up when she's cold her oil pressure is about 1 line under 60 psi and she stays that way even if I let her warm up for 5 minutes. When I start Driving her it stays that high even when I'm stopped for about 3-4 miles then stays at about 40 while driving and at 20 when ever I stop. Is there something wrong with her or is this normal?

You're in the normal range...
Typically, a warmed motor will idle around 20psi (assuming ~1k rpm).
Acceleration will cause pressure to increase... usually along the lines of:
2000 rpm = 40 psi
3000 rpm = 60 psi

When the motor is cold, the oil pressure is higher due to viscosity.

I have about 2000 miles on my recently rebuilt block that is now a 383 with a mild cam. Alpha, my oil pressures are pretty much exactly what you describe.

Same here.
