1970 Dart Swinger FINALLY UNDERWAY

Doesn't seem like the rings are stuck, I can rotate/move them around freely. The piston skirt definitely doesn't seem to be broken, it's not cracked anywhere near as I can tell.

Maybe something WAS stuck in there at one time and isn't anymore? It looks almost like something got wedged between the skirt and the cylinder wall briefly because even though the cylinder walls are smooth the skirt is scored around the bottom and looks like something dug into it. Could it have been something during assembly at the factory?

actually, since you are doing all this hard work, i suggest you take the block, crank, pistons/rods to the machine shop, and have them clean it, and test for cracks/leaks. also, they can check that cylinder,a nd all of them to be sure they are not "out of round"

Yeah I've been meaning to find a good machine shop in my area, couple places I have to stop by but I'll definitely have that cylinder checked. I'm trying to save the standard bore if I can.
