2.7 is a non rebuild-able engine block when it fails typically the crank nose breaks the crank nose main bearing seat.
it also has a issue with under fueling and burns valves.
just my experiences with several of these engines. the 3.4 is far better.
Just wanted to close the loop on my "predicament" or should I say "opportunity".
Mustang is gone.
Jeep is gone.
Kept the 1st Gen.
Picked up a 3rd Gen. for the wife this weekend.
See link for info on the new ride.
