Well it still comes down to the same thing here.Too much oill pressure isnt good for the driving parts in a ford engine.Ive spent my life working in Csterpillar engines.They (3406 ) run 80 psi.The driving parts where heavier then from the pumps of 6 ford engines.Even at that they only required 30 psi in the specs.We used to boost the
oil pressue up for the brakesavers to 30 psi.We had to stop because the gears would fail.Same with the gear driven fuel pumps.We would raise them to 50 psi.In a short time they would fail.They never went much over 2000 rpm.I rebuilt a 289 in my falcon.Ive driven it on and off for 10 years now.She is a screamer you know 8500 rpms no sweat.Used the old
oil pump 5/16 bolts rods,the cam and lifters and heads from a blown engine,I had to rework a pros job on the heads,I got some old 390 heads and put those valve spings in it.. must have cost me $180 Ive have never seen what the
oil presure is to this day.There is a plug in the sender hole.I have a few Go Karts, 20,000 rpms and there is no oil presure in them.The spray from a wd40 can would be to much.
