10 lbs of oil pressure on engine break in..........

the oil galley plug in the rear of block most likely not reinstalled.
Thanks, i didnt check that and assumed they didnt remove it. I really hope thats what it is.

The galley plug right in front of the intermediate shaft gear is also my guess
Thanks!

Stock oil pump or HV HP ?
Stock pump, i was super worried because last build i had fairly high oil pressure 70 cold and 35/40 hot idle.

Did you prime the pump first, this is something I always do no mater what. It's a must to make sure before any install.
I did prime it and it showed 35/40 but not the story since started.
