Your not that far off. The good news is it living. And obviously there is some wiggle room in there, especially since most guys no longer use a 50 grade oil any more. You have less pressure but you are still getting flow. You may be able to back it down a bit more. The question then becomes how much power are you saving to drop another 5 pounds?

When I was testing some of my junk we started back the oil pressure down and lost power. At 8500 I was at 100 PSI. At 80 we lost a pretty big amount of power. I forget the number but 45-50 HP is what I remember. We finally traced it to bushed rockers and the rockers were grabbing the shafts.
