If finances are not the problem and you don't want to work on it then sell it "at a loss" in hopes to save it.
If you want top dollar perhaps pull the pan, pull the rod caps. IF only one journal is scored perhaps the crank can be polished in the truck, and a new bearing put in.
.........I say this because i purchased a coupe with a totally new rebuild that had only ONE journal that spun the bearing and locked it up. I will admit I did pull the engine suspecting the PO had not been totally honest with me. It was brand spanking new inside and even though I disassembled it I would not have had to if I'd only pulled the pan. I saw my father do this on more than one occasion and the engines ran great afterwards.
Still, your decision..........but I bet its cold in Indy!!
.........OH, my engine was locked up because the engine builder did not put the oil pickup tube/screen on when he rebuilt it.
