OH, this sounds like a long block from Ford. If so, I would guess that oil pump was already on engine as well as timing chains, etc. Did you notice your oil light when you first started the engine? How long did it take it to go out? Was it an extended period of time? Prebuilt from Ford the engine would have been assembled and lubed.
Sounds like you did get a defective long block.......good ole Ford -Fixem OR Die with em....
