2003 Dodge Ram 4.7 liter
My daughter had one in a Jeep Grand Cherokee with a bunch of miles (150Kish miles) but they didn't keep it more then 2 years. They didn't have any problems. A friend who works for the best engine machine shop around says stay away from them. They got a big power boost in 2008 so if I did get one I would look for an 08 up. For that price I think you could find a Hemi. Simplier and makes a ton more power with no fuel economy hit. I would pay $2000 more for a Hemi no matter what blue book says.
