Slant six engine and push button tranny for sale

I have a running slant six with push button trans, the part number on the side of the block is 2463430-7 and behind number one spark plug is 122 6 282. From what I have found on the net it is a 1966 225. It is in a 1963 dart and you can here it run before I pull it. Not sure what it is worth but am asking $300.00 for both. If you have any questions please let me know.
Regards!
