340 oil pressure? Help

Ok guys I finally got the freshly rebuilt 340 in the cuda wired up and ready to go and when I started it my oil pressure was around 15-20 on a cold start idle and up to 45 around 2000 rpm. I'm running 10-30 and the majority of people are saying this is super low on a fresh motor and something isn't right. All thoughts, experiences, advice and pointers will be greatly appreciated thanks

I had a similar issue on my first rebuild... It turned out that the machine shop did not put the oil galley plugs in the front of the lifter galleys... Pull the timing chain cover off and then remove the camshaft thrust plate and make sure that there are two plugs behind the plate...
