Anyone ever try this/thought about it? I mean people use LS motors and 5.3 vortecs... Any input would be appreciated, might just have to look into it more. But I was thinking using a lightning engine or even try to get my hands on a gt Mustang engine with some more hp! Not sure what trans you would use.

the 5.4L Triton is not worth it. most of them are crap. i have one in my superduty and it is not something i would put in the jeep. the 2 valve version likes to blow sparkplugs out of the heads because it is only held in by 3 to 4 threads. there is alot of other problems that go with the 5.4L also.

just get a 5.0L with GT40 heads out of an explorer and use a mustang wiring harness and computer. that is the engine i am going to be putting into my cj7 when i blow the 4.2L but mine will be modded alittle more to get around 350Hp. a 351W is another good ford swap.

personally i would never put a chevy engine in a jeep or anything i own but that is just because of personal experience with them.

Any one else care to comment? I don't know to much about the 5.4 but I'm sure not all had issues with throwing plugs.

The only reason i would consider the 5.4 is my jeep is a '04. By law you have to put in a engine of the same or great years (04+). I currently have a 78 350 in the jeep. Just worried about resale. Plus it would be nice to have fuel injection and a new engine!

I have one in my 07 F150 and I like it, mind you its chipped, headers, exhaust and cold air intake. Its not the greatest engine, but after 70 000kms so far I have had no issues. I have thought about this same swap, I have a parts 06f150 here with a running 5.4 with 85 000kms on it but I went the easy route and small block chev on propane.

I have seen no jeeps that have done this swap thus far so it could be first here, never know lol. Props if you do it, it would different.

The size of the engine would be a problem. Then again people have stuffed a viper engine in a jeep... anything is possible.

Although some states vary, doesn't the swapped in motor have to have been offered by Chrysler?
So, in your example an 04 or newer 4.7 or 5.7 (hemi) could be made legal?

Does WI even smog test? if not who is going to enforce the "law".

I would have to ask about that. I was just told about the year issues. My back up plan would be hemi (simple, everyone and their brother have done these swaps). I just thought it would be cool to try something different.

The 5.4 is larger than a hemi? I guess as far as output goes... does anyone have numbers for the 5.4 vs hemi? Then I would have to look at aftermarket mods as well... hmmm i guess this was an open-ended topic lol:flipoff2:

Some places in Wi smog test.. but not around me so far. I could honestly care less. I was just thinking about down the road, if i were to sell it.

Is this the rig in question?

The 5.7L Hemi claims 345HP, 375 ft/lbs torque while the 5.4L Triton claims 300HP, 365 ft/lbs torque. These stats are pulled off wikipedia. The triton number I used it out of the 3v 05+ F series pickups.

Triton - http://en.wikipedia.org/wiki/Triton_V8

yes that be the rig in question haha


alright so really they are both pretty close numbers.

the 5.4 is a rather big engine despite its displacement. The intake alone sticks up damn near a foot above the valve covers.

Not to mention the fact that the 4.6/5.4's torque sweet spot is 4k. Anything under that and they're a turd.

since you would be going with a newer than 04' engine, all the 5.4L you would use are the 3 valve which is a better motor. you said lightning engine in your original post which is why i brought up the spark plugs because all 2 valve engines had that problem.

the only 2 big issues i would see are what trans to use and the electrical to go with the engine. you would need a custom wiring harness to get rid of all the un-needed stuff. you would also need to have the computer reprogrammed to cancel out the ABS, trans, and all other carp as the ford computer reads everything.

I agree, my f150 isn't bad chipped and all but it reminds of a 2stroke dirt bike, hits a certain point toward higher rpm then she takes off.

And rj91jeep has a good point, when my tranny started to act up in my truck it would read a tranny fault and suddenly the motor would spit and sputter and could barely run over 1500rpm. The computer on those motors does read every thing and it could be a real wiring fiasco. It could get pretty expensive. Just a little info.

But I love the motor, good power for what I need and its never let me down. I would love to see this build happen. Hope some of my rambling is somewhat useful.

these are 2 other good statements. my 5.4L usually shifts around 4k and it is not unusual for it to get up to 6k. i have had mine well over 7k and still haven't found the rev limiter. i didnt even think about the height of the engine but that could be another issue

i'm pretty sure the 5.4 is way to wide for a jeep and that is one of the big factors why people don't put them in jeeps.

alright so i guess size does matter haha... hmm well i'll keep looking into it. might be able to fix a few problems (ie. wiring, and low end power) the size is the thing i guess would make or break the idea. I suppose i could just do a hemi swap :shaking:

If its already set up for a SBC wouldnt an LS be a logical choice? get a 5.3 or 6.0?

For re-sell a sbc makes more scence.
The hemi seems over rated and big $$$

The 5.4 is every bit as wide as the 4.6 in this picture. The 5.0 is very close to the SBC in width.

just for shits and grins, heres a pic of a lightning 5.4

With typically lowish gears and relatively low weight of a Jeep, I think the 5.4 would shit and git. The low power complaints come from the larger pick-up owners. We have a few of the light F250s (rebadged F150) at work with 5.4s and 4.10 gears and they haul ass and are fun to drive. The killer though, would be the width, you'd have to get really creative with your steering shaft.
Travis..

Triton motors are shit. I have a V10 in 350SD. These motors are not engineered very well. For power, My ten is fair but it does run constantly lean and sucks the gas real bad. Changing plus is a fucking whore. Fuck Ford. Put a LS or Hemi in it.

Changing plugs in a super duty is a whore because 2/3 of the engine is under the dash. The plugs in my 4.6 Mustang were a piece of cake.

The 5.4 is even wider than the 4.6, the heads are generally identical set atop a taller (= wider) block. since the 5.4's cylinders are longer, running like a stroked 4.6.

and being an over head cam setup, these mod engines are fare taller/wider, I would stick with a 5.0 like suggested.

if you are doing it to be different, dont, you will end up different but it will because your rig sucks, either go 4.6 or 5.0 if you must have a ford motor:shaking:, but if you have the coin to spend on swapping in a triton motor than you can do a ls motor or even a older lt1 or tpi or tbi 350, you will be much happier.
