Whats a good normal oil pressure for a 440

50-55 with a stock pump. Don’t really need more.
 
My apps it was just good to spin it up and oil its old things in a perception.
 
Rule of thumb is 10psi per 1,000 rpm. Plus or minus a little. But a fresh build w cold oil using a drill to prime. Gets pretty high.

Love it doing straight 30 I am impressed you know the rules.
 
Keep in mind that pressure is a byproduct of volume. If you have sufficient pressure with a stock pump, going to a HV will yield nothing other than putting a strain on the pump drive shaft and gear and using up horsepower. If you've installed a HV pump, my suggestion is to try a cleaned up stocker and see what it produces in the way of pressure. If you have 20 psi at idle and 10 psi for every 1000 rpm you're good. A HV pump should be a last resort.

This is always been my rule of thumb.

Anything over 50 at hwy cruising speed is pretty much redundant


ps, My street hemi has a light that goes off while cranking , worst case immediately at start up and I have no idea what it has for pressure ( I may ck it this fall just to satisfy my curiosity )

I run straight 30 weight oil. with a bottle of ZDDP additive and K+N or WIX filter , depending on availability.

I would say no a melling hv is a good pump and its the spring you do for the pressure.
