I recently bought a 94 2 owner vette. THis car appears to have been babied all throughout its 69k miles. everything on the car works perfectly, my concern is when idling, or rolling up to a stop sign the oil pressure reads just above the hash mark. when driving normally it reads around 20 lbs, and when throttling it, it gets up around 40-55. My concern is the idling oil pressure, is this a concern or is this standard for an LT1 engine?

My L-98 will drop to the 25 psi mark when idling that doesn't concern me. It is around 50 when driving.

Have you checked the calibration of your stock, electrical gauge and it's signal? Have you verified what you believe it's reading with a known mechanical gauge? Have it's readings changed suddenly as of late? As a very general rule of thumb and assuming a system of adequate capacity, flow and drain-back for it's intended purpose, 10 PSI per 1000 RPM is adequate. High oil pressure numbers are generally equated with a healthy engine. All things considered, anymore pressure than needed is a parasitic drain on power and an unnecessary load (and stress) on the pump drive parts. I realize this is likely an over-explanation of the question at hand. But the reason is to emphasize among other things, that readings, especially those from an unverified gauge should be taken with a grain of salt. And once accurate readings are verified or otherwise obtained and matched against spec minimums, only then should you be concerned.
