Just got a response from Todd. He is not offering a kit per se, but only selling the parts he manufactures. He sent me a long list of vids to look at.
He said he would need my computer, but mine is a GPEC5???
He sells the various brackets, mounts, and adapters and does some ECM programming. I think it is up to the buyer to source the myriad of parts along with the motor and transmission.
Before I jump into something like this, I will need to have a good understanding of which parts I need and how the process goes.

...Still investigating...
If JSS sold all the parts, you can order from your Jeep dealer, he would have to mark them up a bit to cover his cost which would raise your overall cost of buying those parts. JSS would then be criticized for marking up factory parts and effectively doubling your shipping costs. When you factor in how ridiculous, irrational and impossible to please alot of people are these days... I would do it exactly the same way they are doing it (i.e. supply you part numbers for the required factory parts)

Possibly...
If you have a wholesale or jobber pricing account with the Mopar folks you could sell at retail or even a bit less and still make money. With JSS, it seems to me, they are a smaller operation not set up to handle thousands of orders, although I could be wrong...
For me, as you may know, I am getting a shop to swap in a 6.4 starting on Monday.

They are definetly a small operation and may just want to keep things simple. Likely lots of reasons for doing it the way they're doing it... which is their choice.

Personally I wouldnt be involved in a business that involved the retail public in anyway. People are simply too ridiculous now to tolerate (i.e. do it my way, do it when I want, do it cheap, do it perfect, make me happy). The old common sense saying... "it can be good or fast or cheap... but you can only pick two" no longer applies apparently lol

I commend you for choosing the engine swap & shop that fits your expectations and budget.

For what it’s worth, I know a trusted shop that formerly used jeep speed shop parts for hemi swaps. They quickly abandoned it I found out. When I mentioned this last week during a conversation about passing emissions, the owner told me to run away from their solutions, as fast as I could. The term disaster was used.

If you dont like the "JSS way of doing things" go spend at least double the money and have your expectations met elsewhere.

I think its awesome what JSS is doing... it puts a hemi swap in reach of the average man with some mechanical understanding, ability, patience and ingenuity.
I don't like that he isn't maintaining his website, isn't returning emails, and isn't returning calls.

Not very conducive to me placing an order with anyone, if I have to beg you to take the money, I can only imagine what it'll take to actually get the parts or support if needed.

Sorry the expectations of, answer the phone, answer email, put shit on your site like you said you would at the end of a twenty minute ramble video where you never ever explained how to get the ecm tuned anyway or too high for your buddy.

But I'm well aware of what my other options are, and spending 4x as much with someone who does, answer the phone, does return emails, does return calls, isn't a huge issue to me.

Well then go do it. Why ya hanging around here bitching about a shop you will never use for your swap?

Some people get ignored because of how they interact with businesses (i.e. making themselves not worth the time or trouble) and some get great service. I will leave you to consider that and look in that mirror if you feel it appropriate.

I've already said my peace on it chief, you're the one who feels the need to drag me back to a thread I left two months ago quoting me to cheerlead for this guy 😂

He promising you free parts, or are you just a top subscriber?

Haha... thats funny... I dont know the guy (JSS)... never used him either. I have already stated my position on his shop and JL/JT services and why I conceptually like what he's doing (affordable, as factory stock as possible swaps, for the average guy). You are casting doubt on his company without ever using him so I thought I'd cast doubt on you as a "difficult to please" customer and now you are casting doubt on me for apparently being in his pocket lol.

So in keeping with the game we got going here... take your money and go to AMW where they cut all your mounts off the frame, eliminate your factory steering and give you an ECU only an AMW dealer can flash and be displeased with all thst at "4x" there Mr. 5150.

Back with another quote.

Didn't read a word, don't care.

Party on Garth.

What are you thinking of doing? The 5.7 in his style, or a 6.4?
I do not like the intake-piping strategy for the JSS 5.7 swap. Right angles... no bueno unless uber-smooth, which that setup is not.
I decided that if I went with his setup, I'd use the 6.4 car manifold and go with Mopar parts to complete it.

I'm personally only interested in mounts wiring, and tuning.

The air intake is the least of my worries, can do whatever there with intake and plumbing or 3D printing.

I'd want whatever makes my Mojave hood an actual 392 functional hood though.

copy that
I opted for the Hydro guide hood setup just because of all the engineering. I very much like the Rubicon hood, but since I need a new one, well might as well just make the jump.

The swaps seem to go down at least 1 of 2 paths depending on air intake/cost/factory stock/cool factor priorities. They almost need to be separate threads as the 5.7L swap appears to be quite different than the 392... and the 5.7L people think different than 392 people as well.

Even though the JL/JT was quite likely built with a hemi in mind... it seems to have been laid out (plumbing, wire, air) more for a 5.7L than the 392. I think the 5.7L JSS swap will/has illustrated that already (A guy just has to watch the YT videos).

The 392 intake looks cool but opens up a bunch of different cans of worms. My priorities are to keep it "Jeep dealer serviceable" so modified mounts, power steering, accessory drive is a non-starter for me... that why I am liking the JSS 5.7L GlGladiator swap approach. It is the simplest, least invasive, most factory swap I have seen. Just gotta live with that 5.7L air intake adapter🤔

Concur...
There seems to be several ways to skin this cat. ECM on the driver's side, or on the passenger's side. With the stock PS or with the engine-driven pump. And this swap I am getting into at the moment seems to be somewhat of a hybrid design. (Best of all worlds???).

I'm happy that:
1. I do not have a lift
2. I already put some serious coin down on the hemi swap I am purchasing

Had either or both of the above been something else I might have felt squirrelly enough to take a swing at it myself. Just this morning, a factory crate Demon motor showed up for sale for $15K...I'd have been very tempted.

Oh man... that would be tempting! I'm up here in Canada so no such deals like that every surface and a guy has to add 50% to the USD price to get to the CDN dollar price🤦‍♂️😅

My dream continues to be the Gladiator I think the factory should build which is a JT Rubicon/Mojave, no lift, 35" tires, 5.7L, part-time 4x4.

We own a 2024 392 Wrangler, 2020 JT 3.6L Rubicon and a 2022 5.7L non-etorque Ram Rebel... and when I park all 3 side by side... its amazing how similar the Gladiator is under hood compared to the Rebel.

I'm gonna tackle my own 5.7L swap👍👍🤞🤞
