So ive got the 3.7 liter and it gets tops like 14 miles per gallon on the highway.She has 96000 miles on her and I am now getting the gas cap code. ( changed it still coming on )So I am now contemplating an engine change and I wonder if anyone else has done a change over and if so to what size motor.Like is it any better to put a hemi in it or....
Any way thanks in advance for your input.

 

It's a lot of work and cost to swap an engine over, especially in a modern can bus vehicle. It would make a lot more sense to trade it in for a truck with the engine you want.
