I just changed my oil in preparation for the upcoming Tavares show and find I now have 45 PSI oil pressure at idle cold. (south Florida 85 degree cold). Strait 30W oil was used, with 2 ounces of ZDDP zinc treatment. I haven’t had the opportunity to run it under load yet, but it seems excessive to me. It traditionally ran in the 15-30 PSI range.
Any input would be greatly appreciated.

45lbs cold is good it will come down when warm
