Everything Bubba said is spot on! I have the Stinggray Gladiator in the beginning of the video with 5.7. He tried to talk me into the 6.4, should of listened. Do i like my 5.7? Hell yes, but you always end up wanting more 😂 and $3000 at that point is a mute point. Have over 30,000 miles on it in 3 years and not a problem. Thanks Bubba
Hard to pick between the two engines, mine being a daily and used mainly on trails and not rock crawling I'm liking the 5.7 option. Plus I like the idea of not needing to run premium. Does that extra 100 horses make much of a difference in the gladiator? How does the gladiator drive power wise with the 5.7 ?
@williamcrabby6342 all the same thoughts I had. Mine is my daily driver, camper puller and trail rig. The Gladiator drives awesome with the 5.7 and I do not push it power wise to really need a 6.4 most of my driving is below 3000 rpm's where the 6.4 would shine at or above the 3000 rpm level. Of course now I have had it tuned locally and it requires 91 octane fuel, so there goes the octane argument. The 5.7 is fine, leaps above the V6. But, if you can afford it, just do the 6.4 as it will always be in the back of your mind. Wonder if I should have done the 6.4, as it is in mine. Do I need it? Nope, the 5.7 is awesome, but the thought is always there.
@paulbaker2680 that's a fare enough point, we always a little more power lol. Gladiator will be paid off in 3 years so maybe I can make up my mind in that time. Lol
2020 JT-R just paid off and I would love the added HP! Just hit 45k miles! My need is mostly towing related in the MTNS for my 5k lb travel trailer which adds up to about 5-7k heavy miles a year!
Great video as always. One question--if you bought an automatic, can you also change it for a beefier manual transmission when you're doing this engine swap?
Great info & it's great to find a dealer in Tx... If I do 426 hemi swap, will I have the option to add a long range fuel tank under & double my fuel capacity?
Highly recommend you don’t go that route. We installed a few and they were decent but didn’t make the power they should for the money. I’ve also had to pull A LOT of blown pentastars due to superchargers and the high compression it makes in the newer platform. In my opinion,it’s either Hemi or leave it be.
Great info. Question: would it be worthwhile to do the PSC upgrade on stock axles. Ideally, you'd want to do an axle upgrade at the same time but would be looking at doing it later in the build...
LOTS of customers do the axle upgrade after the Hemi, but it’s either way. Doing the hydro assist during the install is way easier than after, even if you have to change the ram later on for more steering travel.
I have been looking for a swap and this video is great, just a few questions, are you able to have the air intake on the same side as the 3.6 and use a snorkel still? How long does the swap take to do in the shop? I have a 2015 JKU Rubicon and would love to get a swap soon but I'd be coming a long way from Canada :) Thanks
Thanks for the video. I have a 2021 Mojave with 2 inch AEV lift. If I do a 6.4 swap, do you guys buy back the swapped parts like 3.8, trans, Transfer case etc?
Todd at Jeep speed shop basically answered the same question for me in person at one of the Jeep meets here basically he has the JK certified from 07 to 2018 but nothing beyond that it didn’t sound optimistic that there ever would be. However, he did say that because there is a 392 variant of the wrangler now it presumably would be possible to do the swap and certify it however he hasn’t gone thru the process but definitely no on the Gladiator
I have 1 tons on my jeep with a 8" stretch on my 07 jeep jk, the little 3.8l still kicking with 5.38 gears lol abusing it as much as i can. My brother gave me his 11' dodge ram 1500 with the 5.7l should i put that on the jeep and be good pushing the tons around or would it be better getting the 6.4l. already have the donor truck with everything i'll need vs buying everything the 6.4l needs. The truck needs lots of tranny and electrical work so not planning on keeping it, engine is fine had it diagnosed.
What kind of mpg is that 392 usually getting on 91 octane? Only asking bc I’ve got a manual 2014 JKU on 33s and I’m getting about 16mpg. Wanted to see if it’d be about the same if I were to do the swap.
@@Exodus4x4 I have 4.88 gears in it now, on 35's. I'm not looking for anything crazy. Just enough umph to go up highway hills at regular speed. And not 45mph. lol
Can’t take boost? Hellcat is reliably 700+, the Demon is 800+, and factory options in some models. The days of there LS engine are long gone man. At some point you have to let go and move on.
@@richardagostino5085 a 6.2 like I said there good and the 5.7 the 5.7 can take boost better than a 392 u have to rebuild the whole engine the internals are weak. The only thing that's forged is the crank how I know I work for dodge. And who brought up a LS 😆

However, he did say that because there is a 392 variant of the wrangler now it presumably would be possible to do the swap but it would have to be the 392 only and basically look and be factory and certify it however he hasn’t gone thru the process but definitely no on the Gladiator… I don’t know that he would be able to change it. It’s about California air resource board (carb) approval getting it past a ref to get a sticker
