Do a search and you will find more info but will have 25 or so more HP.

There has been a thread on this at least once a week. It will be a 3.7L

Good news about the 3.7L.

Regarding this family of 4/5/6 cylinder engines that GM talks about and the shared parts and related economies of scale. Just curious, what would be the main differences or unique parts that the 3.7L would not share with the other motors.
