Another BBC oil pressure question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Got my big block running and been having some issues with the oil pressure gauge. I am running an Autometer electric, and I am losing trust in the gauge, Put a second sending unit in, and then the gauge seemed like it was sticking at first. Anyway now it is showing around 20 psi at idle, and about 35 psi at 3000 rpm. Went to 4000 and it didn't go any higher. This is with Valvoline 10W30 oil. Does this seem like a safe amount of oil pressure? I may get a mechanical oil pressure gauge after all of this.
