How much oil for this 440?

my 1967 chrysler factory service manual shows a 440. min psi @ 500RPM 20 psi. at 1000 RPM 46-65 PSI. IMHO a small variation would not be bad. my dad told me that if the oil psi came up with the RPM off idle you was good.

very true... dont need 60 lbs hot idle...need bigger numbers at higher rpms..
