Avid reader of the forum, but new member. Figured no better day to finally join than today, because today was a really bad day! The Jeep gods have frowned upon me, my Commander overheated, for reasons we cant quite explain. Within a minute of overheating i managed to warp one of the heads, and most likely damage the block. Since i already have so much invested in this vehicle (and love it so) ive decided to replace the motor. Ill be doing the work myself and dont really mind it, or the additional work that comes with a larger motor. Currently im running the 3.7, but interested in other options (4.7 or 5.7). Curious to how people feel about thier particular motor, pros, cons, real mpg, towing capabillities, realiabillity, etc.... Or some input from others who have also upgraded thier motor.
