I was wondering if anyone has used or heard of a hi pressure oil pump for a 235? my truck only has about 9 lbs when hot at idle and about 25 at 3k rpm. It makes me nervous. i had a mechanic listen to it the other day and he didnt hear any bad sounds. any ideas would be welcome. Its a 57 block and has a oil filter installed. no idea of its age but no smoke when it runs down the road.
