68 340 engine or good block wanted

I have the original block for sale from my friend's one owner 68 Dart and the casting date is 6-19-67. He bought the car off the showroom floor in March of 68. He is the original owner and I was the one who took the engine out of the car many years ago. I also have other blocks of differing casting dates. If this helps let me know.
