Default 350 break in question

Hi guys,
I just put in a new 4 bolt main 350ci motor in the truck. So far...I have really high oil pressure. How should I break it in?

What is your oil preasure? What type of cam shaft, flat or roller? Crate engine or fresh rebuild? If it is a crate motor call the supplier and do as they say. Where is your oil preasure gauge attched to the engine and have you verified the accuracy of the gauge?

The motor is a fresh rebuild, I guess. I got the long block from chevy. The oil pressure needle is 3-4mm from the H. I will find out more information...My bad for not having the information

Did you put a hi-volume Oil pump in the motor?

first thing, get a mechanical gauge that reads in true psi, and see where you are. There may not even be an issue, but with any oil pressure delima I always start by verifying with another gauge. Since you're using one that doesn't even read psi, you definitely need to start there.
