Oil Temp 265 Degrees and Pressure Only 9 PSI -- Did Ford Say That Was OK for a 427?

What I like to see for my personal stuff and what the customers like to see are generally two different things.

Oil pressure takes horsepower. Most guys want to see 20-30 at idle and 70-80 at full song. I can oblige.

Just built a 409 inch Pontiac for myself a few months ago. With a standard volume pump, it was 55 psi hot, at WOT....measured at the filter.

Remember, you'll lose oil pressure from the front of the engine to the rear of the engine. Typically about 10-15 psi. Built a bracket race 408 Cleveland for a guy, it measured 55 psi at WOT crossing the stripe at 7500 rpm. That's measured at the rear of the block, opposite end of the pump. Bearings looked brand new on tear down.

So, measuring at the top of the oil filter adapter, and this is for your own personal stuff only, say, maybe 15 PSI looks good to you at idle when it's nice and hot, and idling below 1000?
