Can i fix this at home?

Heres something you guys might find of interest. I have a friend who spun a bearing in his jeep. #3 cylinder, I think. He bought a new motor for it and said I can have the old one for $100. Surprise its a hemi. I haven't seen it yet and don't know if I can put it in my 66 Barracuda. It is a Chrysler motor. What do you think.
