Hemi or LS swap
Thinking about doing an engine swap in my 07 JKU and getting rid of the sick 3.8 and automatic transmission. I am currently running 37 inch tires with a 5.13 gear loaded down with bumpers, rocker guards, winch, etc. Give me some feedback on what your experience and preferences are.

6.2 LS MoTech Kit
Running 4.10s with 37's getting around 19.2 MPG's and I can run 70, 80, 90 on the hwy, and yes I can I can do a burnout
Loaded down with Poison Spyder bumpers, flares, cage, rocker knockers..
I've sleeved and gusseted the front, RCV's front and upgraded rear axle shafts but haven't done anything else, plan to upgrade to 60's at some point so if shit breaks it just breaks.

Idk about in a Jeep, pushing 37's, but I have had a durango with a hemi and had no issues with overheating. They are heavier that is tru. What sort of LS are you thinking of swapping in?

I've talked with mo-tec , speed shop and a company out of Michigan. Pricing runs about the same with either engine but I'm kind of partial to the LS due to less weight and physically smaller. they make good power and I think they would last longer before needing a re-build. I would like to have a manual transmission but the 6L80 seems to be a very dependable auto tranny. I would probable go with the 5.3 or 6.0L in the LS or a 5.7 in a Hemi.
