Quote: My fresh build (small block) had a high volume pump. I seized it with a small piece of trash that got sucked in. I replaced it with a melling standard flow. My gauge still reads 10-15 at idle (900 rpm) and stays at or above 10psi per 1000rpm.
Gotta be loose bearing clearances? I also run the purple 10w30 synthetic.
yours sounds exactly like mine. (minus the seized oil pump part) this is a tight fresh engine with no more than 40 miles on it. a machineist did the lower end i assembled the rest
