Need Help Finding Engine.

I have a 97 Dodge Dakota Sport. It has the 3.9L V6. I was wondering if anybody knows if I could get a new or lightly used 3.5L V6 used in the Plymouth Prowler, Dodge Intrepid, etc....... I want a later one. the early ones only had around 220hp. i want a later one with near 300hp or higher. just the engine. i already have a tranny lined up. If i can't get one of these i'm going to go after a new 3.9L Cummins Diesel. Any info on either engine will help. Cost, output, and how common it is.

The most common source for late model engines is wrecked late model cars that are being parted out.

I think you may have to call a wrecking yard and see if they can locate one for you.

Also, do you mean a rear wheel drive 3.5 out of a Chrysler 300 or Dodge Magnum? The Intrepid is a front wheel drive platform and a FWD 3.5 engine may not fit well in a RWD chassis or engine. I am not sure on this, though.
