454 oil pressure
What's accetable oil pressure (at idle & 2500 @ rpm) for a '92 Chevy 454 truck engine? This is a hot rod question because the truck containing this engine would be used to pull a 8,500 lb. trailer whose contents include a rod with a Ford engine. Don't want to be left stranded in the middle of nowhere. The truck in question has about 100,000 miles on it with no engine work done in the past. Current oil pressure (when hot, registered on an Autometer guage) is about 22 lbs. at idle, and 35 lbs. at 2,000 - 2,400 rpm. Any help greatly appreciated.
