Oil Pressure Very low on new setup!!!

[429mustang]

If you're worried about it then the only solution would be to pull a few bearing caps and check the bearings out. My van started running crappy a month ago and the oil pressure dropped to 0 after it warmed up when I'd come to a stop. I tried replacing the sending unit, then checked it with an ohm meter, it was working. Then I adjusted my rockers, one was loose so I tightened it (as much as I could, it seemed to bottom out before it was tight enough). It still ran crappy, so I pulled all the lifters, the loose one was trashed, it was worn down and concave, one of hte lobes wiped out on the cam. I put a new cam in it (comp Cams xe274), I put it back together and still had hte same oil pressure. I dropped the pan, the pickup fell off the pump but luckily I already had a retainer bracket from jeg;s that I never got around to putting on (bought it after I put the motor in, they didn't carry them when I built the motor). I put it all back together again and still had no oil pressure. I got to lift the motor again later that day to check bearings, the all got trashed from the metal that used to be a cam lobe so I had the block cleaned up and the crank turned/polished and had a few valves replaced. Now it has good oil pressure ( between 40-80). If I hadn't gone through all the trouble checking everything when I did I probably would have trashed the new cam, so I'd say look everything over good incase somethings starting to mess up.
