Question 350 Oil Pressure

For you guys with a 350. What kind of oil pressure are you guys running at idle when warm? I am running about 20 psi. It goes up the more I am in the gas up to about 60 or 70. Idle seems a little low to me. Thanks in advance

GM's guideline is 10 psi per 1000 rpm. So, at an 800 rpm idle, 8 psi is minimum. 20 is plenty at a hot idle.

Cool, thanks, I thought I read that somewhere, but I thought I would ask the experts to be sure.

at idle, flow is what counts. You could have zero PSI and still be OK, as long as oil is flowing. (tho have a seriously worn engine)
