Olds 350, what oil pressure is normal?

First of all, you should probably ditch that high mileage garbage and run some 10w40 and add lucas oil stabilizer. The high mileage oils don't do anything helpful for flat tappet engines.

Also, the Olds manual considers 8 psi at idle, at operating temp OK. I think that is a little low but my Olds runs around 10 psi when it is hot at idle. Been that way for the last several years with no issues.
