Good friend of mine just rebuilt his SBC 350 with a one-piece block from Summit.
He just fired it up and noticed he's only getting 20lbs of oil pressure and none up to the valve covers. No bad lower end noises so it sounds like he at least has mains getting oil.
Any tips on what he should look for and in what order? Obviously doesn't want to pull it and just start taking stuff apart. I don't know Chevy V8 well enough to even start guessing. He mentioned that the priming with a drill seems to spin really easy and never really loaded up, but the gauge did get to the same 20lbs.
Car ran for about 15 seconds before shutdown due to oil pressure concern and pulled valve cover showed bone dry top end.
