Don't go crazy. It spun a bearing. It is really not that big a deal. You can drop the crank and install a new one with out ripping the engine apart. If you got it before it damaged the rod.
No chance you got the engine from National Cylinder Head Exchange in Orlando? Just wondering.
If you were closer I would be happy to get right in there with you. It drives me CRAZY when someone gets stuck with a poor job. More so with an engine because I have never had one fail that I built.
Keep your head up. Think of all the fun things you are about to learn!
