So I'm bringing this back to the top for the sake of some more discussion... I know that the Mopar 5.9 v8 is a gas hog so thats out... the turbo diesel option is viable but I can't fine one around here for a reasonable price and I think they would be too loud. What about doing some brand crossing and dropping in an LS1 or an LS3? I've seen guys put those in XJ's and get around 20mpg with them.... Worth it or not?
