I have a 91 chevy silverado with a 350 that's been bored .30 over with a turned crank all new bearings rings completly rebuilt new heads manifold and all. I recently put a high pressure oil pump in it. At idle there is about 20 lbs when warmed up. At normal operating there is about 60 lbs I believe. But when I start to get into of the oil pressure starts to drop under high rpms and I can't figure it out
Oil pressure drop in chevy truck?
