Hi, I recently had my 71 455 engine rebuilt by a reputable engine rebuilder.

The problem is my oil pressure is now over 80 psi and pegging my gauge.

I pulled the engine out to replace the rear seal leaking, and they removed the Melling oil pump and installed a new one in case that was the problem, only to have it read the same 80 psi warmed up and 60 psi at idle.

They now are saying this is normal with the new pump.

My question is this normal, and will I do damage running it at that pressure.

Keep in mind I have less than 50 actual miles on this engine.
