Thanks for all the input guys.

DRAM, First off We primed it on the stand with a gauge attached. It showed 75 LBS. constant with a high torque drill. Don't know what else to expect

Last night I drained the Rotella and this morning tried a 5w-30. As the motor warmed up the pressure fell to about 75 at idle and was around 85 at 3500-4000. It looked as if it would continue to fall as the motor got hotter. I had the temp up to 160. Of course that's not necessarily the oil temp but it seems to prove as the motor gets warmer the oil pressure is falling into place.

The old oil pump stated at 65 regardless if it was hot or cold.
