low oil pressure on rebuild

[drew1987gn]

Hi Jack. I'll try to keep this short. Had my motor rebuilt 7 years ago from a local guy that is highly recommended. Just started it this past weekend. Life's been busy, however, I primed the motor, started right up and ran it for 20 min. for cam break-in. My oil pressure after the motor warmed up was at 20psi at 2,000 rpm. I still need to set my IAC but I'm concerned that the oil pressure is too low. I don't have a high volume oil pump. Does this seem low for oil pressure or is this normal for the buicks? THANKS

From the factory, pressure was 10 psi at idle of about 1000 RPM and should increase by 10 PSI per 1000 RPM.

Hmmm, it's on the edge, like Bob said those are the factory specs. The key is how does it respond to rpm's and does it rise up the ladder like Bob pointed out
