Engine swap idea

There was a guy that did a 3.9 v6 swap in a dart on here. Anything can be done be prepared to do alot of fabrication lol. IIRC a 4.0 is an inline 6 correct? Check the length it may not be much different than a slant 6 other than it being upright. You will have to fab some engine mounts I'm sure that's not something you will be able to buy.
I like the idea sounds like a cool build!
