Now I get it...I saw the notch but you had posted "Not a good sign" so it threw me off. Now looking closer I can see where the rod was hitting it...Must of made alot of racket.

I have heard about the same problems with the Mopar Performance Hemi crate engines. I wonder if the same company is building those? Many buyers have installed them and then had them spin bearings, throw rods, etc., on start up. The unofficial advice out in the field is to disassemble them upon delivery, check everything twice and then reassemble and install.

Oh man not cool Steve. I'm anxious to see this car done. Hopefully all the other bolts throughout the motor are torqued.

Root Cause?
Did the bolts come loose and it walked out, wrong crank, or they never clearanced the block?

The crank strike resulted from replacing the factory oil pan with chromed repro pan that was just enough different to take a windage hit. Once again, the bling comes with unexpected expense. Fortunately, that squawk was discovered during engine cranking test prior to start-up.
