After a complete rebuild 440 what is a good oil pressure,, new pump, mine is running 50 at start up... 40 after warm up...is this too much?

If you see as low as 20 psi idling-hot warmed engine, don't fret. A good basic rule of thumb is having 35-40 psi at 2000 rpm hot though.

And 10 psi per 1000 rpm is also a rule of thumb...

What oil weight are you running? Makes a difference

Using 10-30

40 after warm up

Is that sitting in the drive or after a 20 minute highway drive to get an honest reading?

Id say its all good, dont know about others but as a kid with some ragged out mopars 8-15 wasnt uncommon at idle and 30-35 going down the highway and never a spun or locked bearing and that was with 30/50 or at times straight 50.

Its hard to kill these old things.

are these numbers idling or at some RPM? A little high if idling but nothing to be concerned about....just means bearing clearances are on tight side....If this is a street engine no problem....

This 50psi is at idle,, no spinning tires or hot rodding,,, just a show car,, runs great,,, I have 500 miles on it,,, all is good, just wondered about psi... thanks...

Also this is direct reading,,

You are good as gold.

Nothing wrong with your pressure. Not uncommon to have 70 psi or so cold on a BB Mopar. Run it.

Thanks for the replies,,,
