having a engine drop 10 psi or more when hot is is really nothing to worry about as long as the oil psi under a load stays were it.s at when warm or builds Psi as rpm s climb.s . far as pan the dip stick ...stick part that reads full should read the same level if 4 qt or 40 this just tell you the oil level is were it needs to be in the pan . the oil pump pick up should be about 1/2 to 3/8 from pan if a good thick pan you can run them a hair closer . many times the bottom of the pan can suck up to the pick up. have seen many engines over the years. having low idle oil pressure if you think you want to put a HV pump in it the you need the steel sleeve Hd pump drive . if the melling m55hv . before you do this you may want to try a better oil filler and change the oil .if youi go with a new pump i would use the m155 any way you go make sure the pickup fit s the pan
