Wasn't the Chrysler 3.3/3.8 V6 a tank though? Like that engine has a well-earned reputation for just going and going even if it wasn't very powerful. If anything, that V6 in particular will probably outlast whatever it was put into, like there are minivans with 200k+ miles on them probably which have one of those engines and they're likely still going. I really don't see a Pentastar lasting as long as the 3.3 and 3.8 have a reputation for lasting.
