Re: oil pressure?

It's fine. Good rule is 10psi for every 1000RPM.

Unless your oil press goes down when your RPM goes up, I would find something else to worry about.

Re: oil pressure?

on a 350, 15psi can be normal at idle when at temperature. mines ~60-70psi at idle when cold, then ~20-30psi at idle when up to temperature.
