That is what used to be a piston. For those that don't know, it's a bad thing. Piston parts don't belong in the erl pan.
That's where a good piston should be. The wrist pin did some nice work on the bore.
I found piston fragments in all remaining cylinders.
And, somehow a good chunk of piston caused one of the main bearing caps to crack by weging itself between the main girdle and crank.
So, the 4.7 stroker dream is dwindling.

Engine swap time?
I suggest you keep it mopar and swap a 440

There's gotta be a scrapyard nearby with an MJ, TJ, WJ, XJ, YJ, or ZJ you could get another 4.0 out of.

I didn't think breaking a 4.0 was possible...

In 99 ChryCo did a "clean sheet" redesign of the 4.0 in the GC. The 99-06 block won't interchange.
Oddly the "classic" Cherokee got the old block.

If there was only a way.
It was hard enough stuffing a 440 into a Duster with a /6 K member.
Nope, it'd be fun but nopers.

I bought her locked up. Apparently it's not too uncommon to blow a piston on newer 4.0s.

Well since the XJ only had a couple years left in production, it wouldn't make sense to change it.

Damn. I ran mine for 20 mins with a walnut sized hole in the sump and still only had a tiny bit of metal in the sump.
Maybe find someone else's stroker/V8 project and part it out?
