              Thanks for the reply. I know about viscosity and how it changes when the engine is warm. My engine just started to read 40-45 lbs of oil pressure at 4000 RPMs doing about 70 MPH. [...]

   I had a similar problem for a while until I was informed that "modern synthetic oil" is too thin when hot to maintain proper pressure.  Use good old fashioned Castrol I believe was the consensus.  Once I changed the oil from 10w30 Mobil 1 to 30w Castrol, the pressure was normal.
