Hemi swap? 07 with a 3.7

so i have a 07 commander with the 3.7 with 90'000 miles. i havent really had any issues with this engine other than the 5 minutes of ticking at a cold start at the beginning of the day. as for power...meh. id like to have some more considering im used to the 460 in my dually and have had 2 grand cherokee/converted crawlers with the 5.2 v8's. im not trying to get this commander to climb a tree but i would like to have enough power to get up some of the hills ive had to back down. nothing crazy or anything, but i couldnt see why some of these hills are such a issue for this engine. i have my mind set on doing a hemi swap and am wondering what all i am going to need for this. i could see needing a beefier transfercase/tranny, not sure tho. has anyone else done this swap?? any tips or tricks? thanks!

You could do a gear swap from the stock 3.07's to 3.73's.

I would go with the gear swap. To much involved in a Hemi conversion and would cost way more then you would want to invest

Sorry to pile on, but these cars are so computerized, a swap is not only a huge undertaking, but youd regret it in the future when some dealer only module is haywire, and your Vin numbers throughout the vehicle don't line up.

My advise is, trade or sell your 07 and buy a Commander with a HEMI allready in it, there around..
