oil pressure for 427 aluminum block

[Bernica]

Double-check your gauges, then triple check by pulling a pressure check directly off the motor. If you are still running that low, call your engine builder. Since a kid, I was always taught that 40 lbs was where you want to be. If I'm wrong, this is the place for me to be promptly corrected.

Bernica -- I'm posting this for historical purposes only because I know you like this stuff. Here are the specs from my 1964 Ford Service Manual. Note that he would barely pass under these original specs. I also have the Owner's Manual that says "disregard the red oil light if it flickers at stop lights" -- which meant you were dancing around 6psi (and I have posted a pic of that on this forum before). All of this is just for reading pleasure, the OP should not rely on it. We really need more facts....

You are good Sir.
I grew up with the "40psi" rule when running hot. And yes, I was running hard cams....

Hi oil pressure does not mean better lubrication 40-45 lbs. is fine
