WTB - 360 Motor - In Ohio

I am looking to do a swap of my 273 for my 64 Barracuda. I have at least one bad piston ring and it is more cost effective to swap it out than rebuild it. I am trying to take it from 2 bbl to a 4 bbl and the intake alone on this old 273 is outrageous.

I am interested in a complete 360 motor, or as close to complete as possible.

Late model 5.9L Magnum engines are acceptable.
Recently rebuilt with receipts would be great.
Older with lower miles ok.

If there is anyone out there that can help I would appreciate it. I have been scouring Craiglist, eBay, Car-parts and this forum for sometime.
