Since you claimed that you have a new motor built then why don't you ask your engine builder of why you're not getting any oil pressure?
Word of warning, DO NOT RUN THE ENGINE TO BUILT OIL PRESSURE, or you will be rebuilding the engine again.

how are you trying to build oil pressure
most engine builders wont prime your engine since its not a finish assembled product filled with oil
if they installed the front cover some will pack the pump with vaseline which will help it to prime but dont bank on that ...you should not crank it to try to get pressure on a reassembled motor
its the installers responsibility to prime the engine before fire up
i usually do it before the engine goes into the car while its on the stand
you need to fill the oil filter , fill the oil pan, remove the cam sensor and with a drill spin the oil pump clockwise until you have pressure ( you should feel it on the drill ) and with even low speed the pressure should be at the pump bypass spring (usually around 70)
then continue spinning until you have oil at the heads ,
if it doesnt build pressure or flow to the heads.. dont start it up!
then reinstall the cam sensor and ensure its properly installed and adjusted

It has oil the engine I built my self I dint prime it to the motor was in left the filter of to I saw presure coming out but then put the filter on gets full but those not come up to the heads and the short block was build by machine shop like to know did I miss a freeze plug or something simple the pump I did it myself too and I need help getting frustrated have a lot of money in this motor
Did I follow you correctly?... You spun the pump with no filter on, saw oil come out, then reinstalled the filter? And you're saying the filter fills back up with oil?
When you say oil hasn't made it to the heads, that takes time. When you're spinning the drill, is it pretty much spinning with no load, or is it bogged down and pushing back against your hand? If it's bogged down, just keep on spinning. Then after a while rotate the crank 180* and hit it again.
There is a freeze plug that can cause a low oil pressure problem. They're located on the front of the block behind the top timing gear. If one of those were our you could probably find evidence looking down in the cam sensor hole.

Ok I will look at everything again and start fresh thanks
You should have someone else take a look at it with you....You could also tap the openings and use threaded plugs. They are much less likely to fail.

If the engine is already in the car, you can pull the front cover and cam gear and tap new plugs in with some locktite, then stake the block like the factory did so they can't come out. The plugs are 39/64". TA Performance has them. To use threaded plugs, you will probably need to pull the engine out and take it apart to clean the oil passages. There will be too many chips of metal going into the oil passages. You would need a set of threaded plugs from TA Performance, short one goes on the passengers side. You will also need a 3/8-18 pipe tap and cutting oil. I got one from Snap On. It was not cheap, but has done 4 blocks and is still sharp. The plugs need to go in so they are just below the front surface of the block. The tap will just about bottom out in the block when the threads are deep enough. Then there is the issue of the rear plugs. You can see them with a flashlight if you take off the flywheel inspection cover. They are already pipe plugs from the factory. If you did not spin the engine over much or start it, you should be OK.
If that's how it came back from the shop and you built it like that, you just found your problem. Those missing plugs seal up the lifter's oil galleys. On the back of the block, they're threaded plugs. If those are missing you'll notice oil going all over the ground and it sprays out on the flexplate.
It looks like you're going to have to pull the timing cover and top gear to get to them. If you paid the shop to install cam bearings and freeze plugs, I'll call them and say you want your plugs. When installing them MAKE SURE not to go too deep on the passenger side plug. If you look in there you can see where the main oil feed hits that galley first. Don't pinch off that area. On the drivers side there's a shoulder, so that one's easy.
Personally I like to tap those holes for pipe plugs, but that has to be done while the block is bare an before it's final cleaning. You're too far along to consider that route.
