I just pulled the oil pan on my 64 225 and found this. I can't see anything that broken ie. piston, rear main cap. It's aluminum and definitely machined for a bolt or something. It runs great with no weird noises, so I'm stumped. Where should I be looking?

I pulled the pan due to a huge dent in the bottom.
 
If it is running good without any apparent problems, I would just run it and forget you saw that aluminum chunk.
I would keep it though, so when the engine finally explodes, you can match it up with the other parts during the autopsy.......
Just kidding!
To me it looks like a chunk of the piston or possibly the oil pump.
Was the engine redone at some time, or is it all original?
It might be a chunk left over from the rebuild that worked it's way out of a nook or cranny if it was taken apart or rebuilt in it's past........
 
Don't believe the motor has ever been out of it. No stampings on the rod or main caps that is usually done before tear down. I'm going to look at it more tomorrow, but doubt I'll find anything obvious.
 
Gosh, that first photo is not clear but it looks like tig welding on the left side of the “magic meat.”
 
Piece of a repair-attempted rear main seal retainer is My best guess. Slanty oil pump external...

the first time I changed oil in a new 1969 coronet 440-4 speed ,rt , something started blocking the drain hole , reached in w/ a wire w/ a hook bent on it , and pulled a gob of steel wool out --sabotage from the factory , no doubt !

That's scary, have some assembly line "sabotage" stories from years in the shops, & working with guys that worked in Detroit/Dearborn in the bad old days.......
Back to the OP, if somebody re-sealed the the bottom end and put RTV in excess on the retainer bolts, they can hydro-lock & blow out the weakest spot. Think this happened to another member here a little while back....
 
After further investigation, it looks like the ear of a fuel pump. The fuel pump(new) had been changed before I got the car, so I have no idea when it could have happened. Nothing internally appears to have any damage.
 
glad it didnt get kicked up into the timing case! weird
