Default Oil pressure question

i just wanna know what my pressure should be at around 1600-1800 rpms around 20 + good or bad it kinda sucks at idle. motor has about 40000+ miles on it

I think my idle is to low when its in gear its like 500 almost 400 rpms.

Oh yea i have an lt1 camaro

ive been told 1 psi per 100 rpm is okay. I know mine is at 70-75 at startup and fully hot its at 40 at idle and is at about 50 at 1800

Should be around 18-25 warm at idle and it should idle around 700-900. If it goes below 10 at idle I would worry.

Rule of thumb is that you need 10 psi's for every 1k rpm.
