@@Nick_Gir Coming from an LS guy.. the hemi engine is my favorite sounding engine out of all the v8's.. but if u think a hemi can chop as hard as an LS when it comes down to being cammed i'm starting to doubt your even a car guy..
The B roll for the LS engine was cracking me up. This engine is found in a yukon, shows a canyon, LS3 came in corvette shows C8 which doesn't have LS3.
One of the best explanations of this type of modification I have heard. Thanks for addressing the elephant in the room (PRICE). I did an LS3 swap in a ‘67 Corvette and that was about the same money. As much as I love the LS platform I agree with your assessment of staying with Mopar if your doing a Jeep. Of course the pocket book always rules and a used LS sometimes is the answer. Thanks again for a great vid on this subject.
As time goes by that’s not real true anymore. I’ve done 30+ LS swaps in older GM cars and trucks. 11 Hemi swaps. GM crate engines are more expensive. Out of the wrecking yards like LKQ they are about the same.
@@blueduster74I’ve been saying the same thing for the last year 1/2 now as well.. LS is hardly budget friendly anymore although it has more aftermarket support, the aftermarket parts have gotten even more expensive for LS engines.
@@2648498 I heard a hot cam corvette it sounded a lot like a tractor and other Camaro did sound like crap on take off. Runs good but yeah they sound awful
Bubba I had a 5.7 installed in my 05 LJ Rubicon, (formerly Burnside, now Dakota Customs) loved the adequate power but like you said the heating issues finally convinced me to sell it.
We tuned a couple of LS swapped JKs when I was at JBA. That integration issue is a pain. They don’t make as much power as the 6.4 since they use the truck engine. The 6.2 Camaro engines cost way more than a 6.4. And there is no issue cooling a Hemi. So if there’s a problem it’s in the install particulars. We use large aftermarket oil and transmission coolers. I’ve done over 30 LS swaps and 11 Hemi swaps in everything from trucks to muscle cars and Jeeps.
I like the 392 but the 345 is more solid.. especially if u build a older one like a 04 it has a solid cam and tough pistons ..I bet thats y the 5.7 comes in them stock..I like the no VVT..no hassle with cam issues..
I’ve had my Hemi swap now in my 2014 JK for about three months. I decided to take it on a test drive to Tahoe through death valley. The engine ran perfectly cool no issues there, outside temperature was about 110° as hot as it could be. I started going up over the pass, and smelled something funny. When I pulled over I noticed that my blowup camping mattress had melted to the carpet behind the driver seat. I cut away all the carpet, took it to the nearest shop, and had them wrap the muffler in heat tape. It’s about to go in again for a more permanent solution. But other than that driving through the heat, it had no issues. Also I can say from day one, the electronics and everything else has run perfectly, even eco mode. My suggestion would be anybody doing the swap is to pay close attention to the muffler and how close it is to the floorboards. I currently have the stock transmission, I’m waiting for the 10 speed upgrade… There’s some programming that everybody’s waiting on to get it. Great video Exodus!
How much did it cost you? Can you give me some advice before I pull the trigger? My mechanic is giving me 5.7 and a 6.4 option not sure which to choose and what’s the most I should spend on the swaps? I just don’t want to be ripped off. I have a 2013 wrangler.
@@rafetjulevic2743 around 30k, I'm pretty happy with my 5.7. The real bonus for me was it just works, there's not going to be issues like an LS. Just make sure you protect your floorboards from the exhaust lol.
@@PhilBlancett did it feel like you bought a new car. Because everyone’s telling me I should just buy a new car lol my 2013 jeep is still mint, my engine just over heated because the drive belt snapped. I had 200k miles. Did you upgrade your transmission?
@@rafetjulevic2743 waiting to upgrade it, there's still work to be done electronically but I hear the builders are close. I have the stock one and it drives great, so when the 8speed is ready I'll be putting it in. My Jeep was a Starwood motors paint job that I loved, and really I had done suspension and axles already. If you are considering this I do suggest driving a JL. Depending on what you do with your Jeep it could be a great option to go new. It's all a matter of owners choice. I'm pretty attached to my 2014 JK, but JL was on my mind too. I drove one, and the drivetrain is killer.
@@PhilBlancett I regeared my jeep, have fox shocks, fox stearing, I put it in new axles and tie rods. I spent a ton of money. The engine died on my a year later after doing all that. Now if I add the hemi I’m hoping it’ll be like a new car, and I think I’ll need a new tranny. But if I don’t do the hemi, am I able to sell the truck with no engine for good money? I’m just looking for reasons to pull the trigger and get the hemi. Lol
I still want the gm swap, I have a chysler 300 srt8 with the 6.1 and it runs a little hot even with a aluminum radiator and heavy duty fans. Love the power not the heat
Like I mentioned, it seems the cooling is better now than in previous years. I have to be honest and say the GM swaps have worn me out with their issues. Drivetrain is awesome, it’s the bridge between the 2 networks that seems fickle.
That hemi looks good, easier, maybe a roof radiator kit to reduce the cooling and space issues, sure would clean up the engine bay if all it had was an ac condenser and others remote on the roof like oil cooling, trans cooling, radiator and maybe even a closed loop diff / transfer case cooling loop, go with electric pumps to put that wasted electricity to good use. Go ahead idle in traffic all day with ac on the way to the desert to play.
the 6l80 has a .66 final drive and the wa580 has a .67...the gearing must non be the same...and this 392 has a srt-8 intake if the block is orange its a srt engine not a truck motor
Bought 5.3 for 4K with trans. Spent about 1500 with Novak. 2k fir computer and fuel system. 2k for labor at the shop . I have to get the exhaust , new driveshafts and done. 30k ??? Burn
LS all the way, hemi's are hot but break more often, too many parts and more complicated to rebuild due to head design, far more options for LS, parts are usually cheaper and more accessible too
I wish Jeep would wake up and offer a Hemi from the factory. I really like the sound of the LS ! I can see why the 392 is more practical, both are great engines.
Not many people willing to pay $100k for a Jeep off the lot, those who are have no problem taking it to a shop that will do it for them. Jeep would lose money engineering and producing that vehicle
@@tonyestrada6747 Idt you're giving Jeep enough credit on some of the weird shit they'd be willing to do. They do make a 6.2L 707 hp Cherokee after all, you're paying almost 90K for it but they put it out and people are buying them. I personally think the people who would be willing to fork over the cash to pay a shop to Hemi swap their Jeep would rather just buy it new from the lot that way. They can just drive off the lot and actually have fun with it instead of picking one up, and giving it to the shop for months on end, then having to worry about what could go wrong depending on who they took it to or warranty issues, electrical gremlins, etc.
@@c4onmylip thats true or you can just wait a couple years and buy a used hemi Cherokee for way less either way what your saying is better, I wouldn't give a shop 30k to do that it doesn't make sense
@@vee950 yeah, I agree. I don't think the hemi cherokees are gonna go down that much in price to be honest though. They only made them fir a few years (I think this year or next year is gonna be the last year for them) and are relatively low volume so I think they might hold their value, which was close to or over 90k. They were dumb expensive. Honestly, the cheapest route would to probably finding a wrecked SRT or hellcar and doing the swap yourself, but it'll be alot of work for us normal guys.
I’m about to do a complete rebuild on my LSTJ going independent computer, EGR delete, and trimac transmission, the 4L60 has given me nothing but headaches
Its clear... The men is a CHEVY BOY. Its waaaaay better the 392 than the 6.2. Im stock form it produces at least 490 hp. He dont know nothing about hes talking
IN THIS PARTICULAR COMPARISON THE HEMI LOOKS CLEANER BUT IVE SEEN LS SWAPS LOOK SUPER SUPER CLEAN AS WELL. I KNOW A DIFFERENT INTAKE MANIFOLD WOULD LOOK ALOT BETTER..AS LONG AS THE ENGINES DONT HAVE DOD I HONESTLY THINK THEY BOTH ARE GREAT ENGINES. AS LONG AS ITS A GEN 4+ HEMI THEY ARE A GREAT OPTION. MY DADS GOT THE 6.0 AND ITS GOT A VETTE INTAKE MANIFOLD AND SOME OTHER BOLT ONS AND A CAM. I DO LIKE HAVING THE GM TRANSMISSION. ALSO THE LIGHWEIGHT ALUMINUM BLOCK HELPS WITH STEERING COMPONENT WEAR AND TEAR.
The 5.7 is one of the toughest v8s that dodge has, handles about 15psi of boost (~1500hp with full bolt ons) so if you want to make a racing motor the 5.7 isn’t a bad choice
@@braedentrebell3718 for that motor to take 15 psi of boost you need to stroke it out to a much less compression ratio or else I don't know if it can even take 3 or 4 psi!
Like your channel man and I will. He has been doing LT swaps a few years now says he has it down perfect now so will see I guess says the 8 speed transmission works great with it
And I dropped it off about 6 weeks ago he has the motor and transmission in a while ago I’m just waiting on the 72 inch dynatrac 60s axels to be made they should get them around the 16th but he did tell me they were 3 weeks backed up cause of the virus had to shut down a little while getting a beefed up atlas ll I’m hoping that comes when the axels do
The 6.4 is in that is rated at 485 hp not 410 and is actually making 500hp at the crank no cam swap required. And the cam swap is not any harder. The truck 6.4 is rated at 410hp but has a different intake. Your only producing the extra hp if your running wide open throttle, if they are going the same speed they are making the same heat, if your having cooling problems with the hemi in that it is installer error, tuner error or bad parts somewhere. There is no reason to be having cooling problems. One electronic system is bad enough two is a nightmare.
Let’s be honest....the squatted trucks and the YeeYee boys really killed the LS variants for many of us....and the sound is still good IMO, but god all I picture is a squatted busted Z71 when I hear a mild cam and loud exhaust behind any LS....they all have that “blub blub blub blub” tune that gets under my skin. That’s just me though.
why do you say that. i am reading these threads and there seems to be two followers, LS and HEMI. it is very confusing, i am definitely not a mechanic. i have a 2010 4dr mall crawler rubicon and want to keep it. I am in the research phase for an engine swap. i really want to keep my manual shift. why the LS, why bad reviews on mopar. i wonder if there will be more computer issues between LS into the jeep.
How reliable is the Hemi Vs the LS? I'm usually swayed by the ease of maintenance/cheap parts for GM stuff, wondering is that still the case with these newer engines, and we all know about Chrysler's reputation. (I am a Jeep owner.)
The ONLY downfall with hemi (gen 3-gen 4) is it’s fairly new to the aftermarket scene. So if money’s a problem that’s your sign. If moneys not a thing anyone who says the hemi is junk is full of complete shit and probably thinks the earth is flat.
My 2 5.7 both grenade at less than 100k. I have a 6.1 in my 300 it runs, but I LS swapped my charger after working out the disagreements between chrysler can bus and gm ecu I'll take the LS any day of the week. It runs smoother has more power and will smoke my SRT8 6.1
I feel like the Coyote would be a lot harder to swap, mainly for the fact that the heads on it are massive, the hemi heads are pretty big but the Yote's are bigger, not a whole lot of room to shoehorn that thing in there but I'm sure it could be done!
I would love to see you show the process of why $35,000 is the cost of this swap. I personally do not understand why it cost as much as a nice new car to get this Hemi swap done?
Thank you for the video, excellent information. As far as trail performance, rock crawling at a hard trail like moab, how do they perform is one better then the other?. Thank you.
Mopar makes a 426 (Aluminum) HEMI Gen III Crate Engine: The Mopar 426 Aluminum HEMI Gen III Crate engine assembly includes the intake manifold and oil pan and offers 540 horsepower and 530 ft.-lbs. of torque. Part Number (PN): P5155513; Manufacturer's Suggested Retail Price (MSRP): $13,675.
don't worry, if you're willing to put the money in for a v8 swap in a newer jeep in Cali, you probably already know the loopholes on out of state tagging if you can't pass emissions with it lmao. "hey bro, Nice Montana plate, what brings you down here?"
Doesn't the LS swap require a CANBUS conversion unit that allows the GM sensors to operate and be converted to Chrysler's signalling? That's what I was told when I called a few of the big LS swap shops like Motech. That's a major reason I went to the Hemi because its just a flash on the ECU meaning there's no additional crap to fail on me. I was told one year multiple people at EJS had their Motech "box" fail and they were 6 weeks behind on backorders so people had to get their Jeeps towed home. I have no idea if these stories are true, but it was enough to scare me off doing an LS swap. Edit: You talked about it @ 5:10. That's a major point of failure. Yuk. I can take my JKU to a Dodge Dealer and have the service department work on it.
@Exodus 4x4 say I already have 2012 2013 , 5.3 ls ,with trans and t case for either jk or gm, and all accessories, ecm, gas pedal and bracket, engine harness etc. , not including mods to motor, transmission etc. Pretty much mounts ,harness adapters, to run engine and trans, and all jk instrument panel work like stock. Do u have a # u can throw out there ? Just sumwhat close
Honestly putting a general motors engine in a Chrysler is a sin imo but to each their own if I ever had a jeep it would be swapped with a LA engine 360 stroked bored to 410ci easy 520hp 550tq with right intake, cam etc... Not to mention it belongs in a Jeep and second of all people sleep on these magnum engines also they hit peak torque lower RPM range than the new hemis better for off-roading If I was going to go nude would have to be a 345 the 392 I'm not a big fan
I have a 2020 Gladiator. Not really interested in a swap at this time but wondering about options for this platform. I rarely see anyone talk about doing a swap with a 5.7 liter Hemi. What is the reason this? Not enough bang for the buck? or something technical. My main priority would be reliability and as close to seamless integration as possible. Thanks, Brian
@exodus 4x4, nice explanation! Definitely will go for a 392 or Hellcat! Do you know if some skid plates are compatible, or do you have to go custom plates when you engine swap?
So... Since the JK & JL is a "passenger vehicle" and the JT is a "truck", does that mean that you can now put LS motors in the Gladiators again? I have been wondering which direction I would go with my 2020 JTR (8-speed auto)... But I'm leaning towards the 6.4 Hemi, if I can get it done under $25K...
