Is anyone running a 4.7L???

As a whole I like the 4.7 in my 2000 4x4 Durango a lot. Breaks the tires loose like a champ, pulls hard and sounds pretty damn good with the stock exhaust system. It's sitting right at 220,000 miles and all it has gone through is a radiator, and two clutch fans, although I am in need of a valve cover gasket pretty bad. Mileage is really not that great next to other comparable mills. All that being said, I love it in the Durango, but defiantly not what I would consider swap material. Pretty much like everyone else said, too much work, too much $, and almost no aftermarket support, other than K&N and flowmaster
