At an idle what kind of oil pressure are you guys running?

 

Depends on engine temperature. My LT1 idles between 60-70 psi on a cold engine, around 40 psi if the engine is around 190. At 200 degrees it's around 30. If the engine gets really hot, it might go down to 20. This is with 106k miles on the clock.

 

I'm at 60-65 psi when cold. Operating temp I'm around 45-50, depending on my rpms. Lowest it's gone since new oil is 35 psi and that was with the temp gauge 3/4 of the way up. 125k miles.
