You will also notice above 4K rpm the
oil pressure only increases 2.5 psig, this verifies what Melling told me about
oil pressure levels out above 4K rpm. His
oil pressure was just below 60 psig but he was using straight 30W which is more like a 10W40 viscosity. Its amazing how close his dyno sheet matches mine. Once again excellent read with all part numbers, torque values and clearances.
