Super bummed. New motor. Bad bearings?

The reason I ask about the crank bearings and cam bearings being assembled with engine oil only.

Is that if they had been assembled with Lucas assembly lube (like STP) it is much thicker and goes down first and then the bearings assembled.

This thicker lube gives a better oil film and allows debris to float on past the parts without imbedding in the fresh soft bearings.

Would be interesting to hear how exactly it was assembled and what lube ?

Did the machine shop install the crank and bearings, then you installed the cam yourself?

Now you have 2 different people building on the same engine, things can go wrong.
