Duke and Joe L., FYI
I finished the rear main seal and oil pump replacement on my 67 BB this weekend. The oil pressure on cold startup was about 55 psi at 1000rpm. After warmup to 210 it was about 45psi and at 2500 rpm back up to almost 60. The oil is Rotella 15W-40 and the engine has 800 miles on it. The pump is a standard Sealed Power (Federal Mogul) replacement for non SHP big blocks. $57 at Napa including pickup screen. The Melling M77HV that was in there pegged the gage at hot idle. The best part is the oil leak is gone; ripped rear main seal. On to other projects. Thanks for you guidance.
