Have you plugged the bypass? There is a small plug that drives under the rear main bearing or the oil pump,it could have got drove out when cleaned and not replaced.

What's considered 'pressure starts to drop'? From 80 to 60? 60 to 40? 40 to zero?

It's common for pressure to drop once the oil gets up to full temp. Also, 10w40 will give a bit less pressure than 20w50 etc etc.

Many variables and need more info. Running 50-60 PSI after 3-5 laps wouldn't concern me at all with 10w40. Wouldn't concern me much with 20w50 either.
