I would rather have the ls. Chevy just builds a better motor, and I can attest to their durability.

5.3l LS. $600 300,000mi engine with enough power for a Jeep and easily upgradable from cheap stock parts, ls6 can, heads, intake, etc.

I agree there are more Hemi swaps right now. There may be more Chevy's in older YJ,TJ models but doing JK's with emissions ls swaps are more recent. I like both engines but the ls swaps seem to be more advantageous for cooling & mileage, support.

As long as one can tune all the mods to keep the JK nanny systems happy.


I have the 6.1 Hemi which has been in since 2009. There was no LS kit in 2009 as far as I know.

This is my first Mopar motor since a 70's era 225 slant six, but the SRT built Hemi at least is not junk and has worked flawless. It has provided me so many grins that my face is all stretched out.

That said, if the LS 6.2 install had been available with the bugs worked out I would have had no problem going with that. One of the primary reasons would have been the auto tranny that it comes matched with.

I have owned many GM small blocks and agree they are stout motors and cheaper to build horsepower in.

If you are going to go all crazy and put a V-8 in a JK, I do not think you will go wrong with either one.

lets not talk about ford. that's were I draw the line lol sorry ford lovers I don't like that ball game.

if that's the case that is something I understand and is why im 50/50 even though LS seems more of a better platform to me. I believe in stay true to the maker.
I have followed every swap thread I see on 3 Forums. I will do it someday $$$$. The important thing I look at is how serviceable will it be? I would use the AEV kit for the Hemi because you can get it analized at any Jeep dealer. The LS is the same way when done like Motech does it. I would be afraid to get a one off swap installed and have a problem no one can diagnose. Also resale is important. Most of these well done swaps are bringing 17000 - 20000.00 grand over a V6. So it can a reasonable return on investment as toys go. Come to think of it I haven't seen a JK for sale yet with an LS installed?

That is probably because they did not have the process ironed out enough to market putting them in a JK until fairly recent. Lots of R&D involved to make it turn key, I am sure.

So I went with a 6.4 Hemi in My JK, and I have been completely satisfied with it. AEV tells me I have a full 3 year 36,000 mile warranty on the Jeep. AEV warrants their part, and Jeep warrants their part. The LS may have more aftermarket support, but the Hemi I have has more factory support. If I have a problem all I need to do is take it to the nearest Jeep dealership, instead of finding an aftermarket facility that can handle an LS transplant. At least that's the way its supposed to work, time will tell. I am very happy now though. No overheating, and no transmission problems with the six speed WA580 transmission. The Jeep drives like a dream.
Actually when the LS is installed and integrated withe Jeep system but runs the engine & tranny on a stand alone sytem it can be diagnosed by any GM dealer. I like your Jeep and AEV products a lot too.

He dropped his rig off there in June and it has yet to be completed. My hemi swap took 6 days.

Also, youll find plenty of hemis on the straight track!
That's great turnaround time, who did your swap? Any overheating pulling our mountains?

I have the 5.7 Hemi from a Ram 1500, yes it runs a little hot, I can maintain speed on hills without downshifting, I have the power to pass anyone and I'm on 40's. I also have enough power to bend my axles. My JK ran hot with my supercharger, hot enough to blow the engine, that's why I went for the Hemi, it was the only other option at the time. Oh yeah, it sounds fucking awesome too.
