Dan, be careful how much you crank up the spring pressure on that adjustable
oil pump. I'm running a similar Mellings unit and I ended up turning it back down to stock because I was seeing too much pressure (after I decided to turn it up some). I run straight Kendall 50 SAE and my pressures are stable. Mid 50's upon start-up and reaches low/mid 60's until the
oil gets warm. Then maintains 39-40 at a 800 idle when fully warmed up. You only need 10psi per every 1,000 rpm to get effective lubrication...anything above that and you're just pumping more
oil than you need and working the oil pump that much harder. I see at least 60 psi at my redline of 6,000rpm (rev limited...I don't twist this particular motor as hard as I have others...this one doesn't need it).
