427 oil pressure
Keith
I have a thread on 427 oil pressure. Being one of the gurus here, can you check it out and comment? Thanks Tim |
Give him the link to the thread you are talking about - make life easy for him.

The answer is you need 5-8 psi at idle and maybe 35-40 at speed. More than that and you begin to rob the engine of horsepower and will wear parts faster. That said there was a reason S/C cars came with 160 psi oil pressure gauges. Send me $20 and I'll run mine up to 160 and send you a photo. Melling swears the HP pumps actually induce less wear than the HV units.

Oil pressure
I also would be interested in knowing, and from what I can gather on most high performance road and race engines, 50-60Ibs Hot at max rpms seems to be normal.
We have a guy here in NZ who races a 62 Galaxie with 427 engine, he blew a few engines years ago but now has it reliable with a modified oil system and 100psi oil pressure, but to my mind why would you need so much to keep metal surfaces apart unless the engines arent built correctly. |
