It would be a problem getting it in there.
There isn't enough room to get the 3.0l into the engine bay.
The chassis wasn't designed for a V6 so you would probably have to completly fabricate a new front core section. I'm not telling you it can't be done. You could easily end up spending $10K on it and have a car worth $0 when you got done.
You would be better off putting a SRT-4 engine/transmission into it.
