What is your oil pressure range on your 5.7L/350?
I just started keeping an eye on my oil pressure gauge. I notice it is right around 30psi anytime I am off idle, about 20psi when it's cooler out when idling and about 15psi when it's high 80's-above.
Is that normal?

I've been told for a stock application you need around 10 PSI per 1000rpm. Mine usually runs 50psi when cold at 3000rpm or so, 40psi at idle, and when it warms up, it is usually 25-40psi.

GM states 5lbs per 1000rpm. 7 at idle minimum.
