its the gearing of the 2.7L. SO its not the engine.
Take a special vs any 2.7L and you will see the results
So ya its the 3.5HO FTW.
The 2.7L is just too much of a headache and i would be deathly scared to drive one after all of the reported problems. Even if Chrysler claims that they fixed the issue after 2000, you still see lots of treps going for 500$ with a blown 2.7L.
