Ubolts too big for my shock plates

Had a friend years ago that was a self proclaimed master engine builder. Race engine,truck,car, it didn't matter, he was the man. I was about 16 at the time. If front of a bunch of guys standing around, hanging out. So he is building a 327. Without thinking he picks up a piston/rod assembly and says "Oh this is great, how am I suppose to know if this is number 6 or number 9" You could see almost instantly his face turning red and wishing he could take those words back. 46 years later we still give him hell. Yes it happens to everyone.
