Oil pressure concern

Tuff to say what could be amiss. If anything. It's nice to know clearances when the engine went together. Especially in the main/rod bearings. How were the lifter bores/lifters. The type of pump has a large bearing on pressure. If you take the pan off, check the pickup for tightness. They are sometimes loose and pressure will be lost there. Oil filters can affect pressure, at least in my experience.
I recently went with 5W50 full synthetic in my Super Bee, (10W40 is no longer available here) and that picked up pressure at idle (hot), and down the road.
If it was a stock type pump, with typical clearances for a freshened block, I don't think your pressures are a concern.
