Howdy fellas,I put a rebuilt 292 in my truck and the oil pressure was showing low when I put it in but I was hoping my factory gauge had gone bad sitting up.Today i hooked up a quality snapon tool oil pressure gauge to the engine and I have only 7psi at 700 rpm idling in drive.At 2200 rpm I have only about 18psi and at 3500 rpm I only have 23 psi.My old 250 had 30 psi at idle and 45 when cruising.Anyway I was wondering had any of you experienced this with a rebuilt engine.It came with a new oil pump or maybe rebuilt one -I can't remember but I do remember it was a Mildon pump.This would be the easy way out for i sure hope it's not due to bearing clearances.Any responses will be appreciated.

Sincerely,Gerald
