Well, the verdict is in.

Got the engine on the stand and flipped over to remove the oil pan. It was pretty easy to find the rod that was loose. Rod #1 has the babbit completely gone and the crank is scored. It's a shame as measurements revealed that this crank was standard size, with the scored #1 crank pin just a few thousandths under standard size.

I'll be holding on fixing it till I get the 235 freed up and see if using the crank and rods from it will be an option. If I go with the 216 crank and rods (will need one replacement rod), I'll likely put in aluminum pistons. I'll need to measure the bore size before jumping in to that.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
