1992 5.2 Magnum

My first post on the forum!!!!!!:newb:

I have a 1963 Dodge Dart in which my Slant six blew up. I am debating between rebuilding that or putting my 5.2 Magnum in it. The 5.2 is in a Dodge Dakota. I have the whole truck from top to bottom. The only thing wrong with the Dakota is that the transmission is bad. I also have a small block 727 transmission.

Question 1- Can I put the 727 behind the 318 FI?

Question 2- What problems would I encounter with that?

Thank You!
