I have a 89 5.0 in my Cobra with a HV Melling
oil pump. 65 psi cold and 50 hot. Water temp 195 and
oil temp is 160 ( 7 qt
oil pan ) 180 when I am a quart low. I orginal installed a HP / HV oil pump, pressure was 95 cold and 80 - 85 hot, 105 at 5700 rpm. I blew the remote oil filter o ring. Two and half quarts of oil up my windshield and thru my hair. I changed the oil pump! I have 17,000 miles on the motor / HV oil pump and no problems.
