Throw throw a v8 in that biatch.
thing is......with the way gas is going......and those dodges don't get good anyway, except the cummins.......your way better off by throwing in a v8. You might even get better mileage than the v6 does now. Lighter vehicle, more avalible power = less effort to move = less fuel consumption.
I really should shut up now.
Drop in a v8. Do it.
