Normal Oil Pressure Readings

Just to be on the safe side,

What are the normal oil pressure readings in a stock LS1 w/ 5w30?

Reading off of the stock gauge...

(i tried a search but it didnt narrow it down any)

Off the stock gauge, I typically see 60psi at startup and when I get on it pretty hard....

Once warm and at idle or cruise, I typically see ~40psi....

I have slightly over 40 warm at idle and slightly over 60 cruising at 1500 rpms. 5W30 synthetic.

if I sit idling for while and the engine gets hot, mine goes slightly below the 40 line. Hot at a cruise 50-60

I read somewhere 10psi is needed for each 1000 rpm's as a general rule
