Motor Swap
 

Sounds close enough for me?

Not that I've ever swapped an engine, but:

Sounds like that could possibly be a 1 to 1 swap (all parts match up). However, I don't think dodge offers a stock 3.5 with supercharger. That could mean that accessories had to be moved to accommodate the blower (especially if it's centrifugal).
Depending upon how involved the guy who plugged in the supercharger was, he may have gone as far as to swap parts that link up the crank to the transmission, engine mounts, etc...
There are a lot of things you might possibly find out only after having started the project.
Always best to make a lot of room in schedule and budget constraints for any engine work, and that goes double for engine swap.
