Well I had mad a few trips on the Motor with oil pressure @ 50-60 psi @4500 all day. Water temp won't hit 130 so I'm replacing the Stat before next trip. Anyway, the Guys that are running low pressure Beside Redstinger's near disaster, change out your Oil filter to the K & N HP-3002. I did and I picked up 20-25 psi.
Some of the Oil filters out there don't flow well enough for this Big Motor. I was using a short Mobil-1 filter. Forget the short filters, go long. More surface area.

Now for my next big Challenge, go from 2 MPG to 6 MPG. Offset with Plasma & Hydrogen.
