Here's an unusual one...

When i worked for dodge they chrysler rep told me there were a hand full of of v6 4 wd drive durangos built , i never saw one , but i bet they were way under powered . This is just a case of someone having a durango with a bad motor and someone with a good slant six and no place to to put it . I think in any state that has emissions testing for inspection it will be hard to get it inspected
