I bought one of those butler blueprint 60-70 pumps and had it installed on my latest build. I put the little washer in for the 70 psi. Looking at video of the dyno run hot idle was around 19 psi , 3500 rpm’s was average 60 and 5500 was around 70 psi . Bearing clearances was around .0028 for rods and mains. 15-40 oil. Installing the engine in my car currently and should have it running this week,,, we’ll see how the oil psi shows up on my gauges. I wish I had known about these pumps,, I would have had the engine shop double check it. I also installed one of those nitemare oil pump shafts.
