Didn't single one person out. I'm sure if I had more money then what I knew to do with then I would do it also in which case I would consider myself retarded. Wasn't meant to be rude. Guess I should have said ridiculous or something else other than retarded. My apologies.

From the research that I've done and talking to Robbie at Mo-tech it appears that a used motor and transmission swap with less than 40,000 miles will be between 16 and 19,000 dependent upon what engine and other modifications that you go with such as exhaust, tap shift and cruise and so on.

The way I look at it is, I use my jeep for work and play, I use the jeep for work and it sees some rough terrain and is in 4wd almost every day. I have had to beef it up to keep it from possibly breaking down while at work, Pro rock 44 up front with lockers front and rear, bumpers, rockers, and lights. I bought the jeep about 2.5 years ago with 50,000 on it and now it has 140,000 and the 3.8/auto will not last very much longer. I can spend 16 to 18 on an engine swap or buy a new jeep and start over. If I stay with the 3.8/auto and go with a new engine and beef up the tranny I still have a weak P.O.S. that will continue to give lack luster performance and be problematic. There is only one financially feasible option here the way I see it. Once the swap is completed I will be able to run the jeep on any trail in the country and have a dependable work vehicle.

I went with the 6.0 mainly because Robbie scored a killer deal on them ($3K for a new one). The one in my Jeep is pushing 400HP / 420TQ. I've driven his 6.2L LS3 Jeep, and despite the smaller displacement, they perform about the same. The real bonus is the 6.0 is designed to run on 87 octane fuel. I give up a few ponies (and probably a little MPG), but it's cheaper on the wallet to maintain. I'm also running the stock D-44's in my Rubi with the stock driveshafts. To date, no issues. I'm not afraid of the "go" pedal either.
1. Never merge onto the interstate in your Jeep
2. Have no hills or mountains where you live
3. Have a 3.6L with no weight additions.
For me, the difference was night and day. Doubling the horsepower and torque makes the Jeep feel like a "normal" SUV (think Chevy Tahoe or Range Rover.) I no longer fear for my family's life when I merge into traffic or traverse steep grades.
As for performance, no need to explain it: Here's a short video compilation I made last summer

LS/HEMI in a JK
We have been doing Hemi swaps cents 2004 and the Hemi has been great and the all NEW VVT Truck Hemi with our new program is the best HEMI yet.
Now we have done about 15 LS swaps and my Jeep the GuineaPig has a 2010 6.2L/6L80 that we put in a Year ago, I always have been a Chevy fan, but the Hemi is just easier to install.
Now the LS is a great engine and their is more Chevrolet fans out their and with the 6L80 it is a good program, so we are working on a simple way to install a LS in a JK so we build a all new wiring harness, we also use the LS accessory drive so we can have a York air compressor. We also can now use the Rubicon T Case we have build a shaft so we can use the Rock Trac 241 T Case.
It is hard to do any engine swap on the cheap, but we can do a VVT 5.7L Truck HEMI turn key for $16,800.00 (400HP) and no over heating with our new fan and shroud, with our new program we have help the trans also by raising the Rev-limiter in each gear and making the shifts firmer. We have come a long way with the Hemi!
Now it is time for the Chevrolet LS and we are going to make it better that ever, we have the HEMI Jeeps down and working great so it is time for the LS!!
We are also looking into a Diesel 3.0L but this will take a lot of time and work, but we are looking into a Diesel also!
