Here is a little info from the ALLPAR.com site on the 2.7 and 3.5L.
The 2.7 and 3.5 liter engines were used in the 2008 Chrysler Sebring and
Dodge Avenger with some changes. The 2.7 was downgraded to 190 hp and 190 lb-ft of torque, but reportedly had better low-end power. The 3.5 was downgraded to 235 hp and 232 lb-ft of torque.
Another change from the 3.3 to the 2.7 was switching from a timing belt to a more-reliable three-row chain.
