did you ever think about just putting a different engine into it? I'm not asking this to stir anythign up, but the 5.4 wasn't that great of a engine to start with and with so many new offerings from both ford and gm that would be easy to swap in and would give you more power and better fuel economy. for example a junkyard LS 6L could be had with a trans for about 1500 up here so 1000ish down their and prople about another 500 in parts to install it, I bet you would be well over 15 mph. I know its a gm motor in a ford, I am just using it as an example and it is the cheepest way to go, the ford gas engines that would make a good swap are a little more money.
Ain’t no old LS getting 15mpg in a 3/4ton 4x4.
plus F250 LS swap? Rofl. Can’t see anywhere that might get difficult or have issues…..

no it would probably get better. 🤣
LS into anything is easy now days, they make mount kits for almost any aplication you can think of, and their cheep including the harness or you can buy an aftermarket harnes and its all plug and play for the most part. that was just an example, like I said, a coyote swap would be fun also but I think its more suited for hot rods and not things that need low end, and its much much more expensive. I even have a friend who put a cummins into a old ford 1 ton 4x4 , we had him comitted for using that POS engine but he did it 😆
seriously thought, myself and my two buddys have now swapped about 15 LS motors into classic trucks some as old as the 40's but a lot of 1960's and 70's stuff also. a few of them are street/strip procharged, one a turbo setup but the rest are all naturaly asperated and if you keep the foot out of them they get amazing milage. its all about building them proper for what they are going to do.

Agree, LS swaps are very popular now. Considering it for my C10 actually.
Doesn’t mean it remotely makes sense to swap similar technology and power for similar technology and power + a pile of money and a bigger pile of compatibility issues.- StirCrazyOct 28, 2024Moderator
haha a ford 5.4 turd is hardly simular technology, there is a reason ford dropped that motor, along with the 4.6 (which I think was a way better motor than the 5.4, less problems.
I am not sure whyere the pile of money comes into play here, a LS is a very cheep swap, if you are good with wiring and figuring out schematics then you only need the full junkyard harnes for the motor and the motor and trans. so 1000 bucks give or take where you live and depending on which LS setup you want, but a 5.3 LS will way out preform a ford 5.4. and I am a die hard ford guy saying that... when we put them into something like a 49 international it is ualy about a 2K job if we can get the wiring harnes with the motor, orther wise 3K if we have to buy a standalong harness and comuter. its the cheepest 500 hp you'll ever make if you get a 6.0 a cam and tune it...
now I would love to swap a cyote into something but thoes are expensive, not enough of them on the road yet, but for 7K you can get a used cyote and put it in anything and then spend another 9K on the 3L whipple super charger setup and have one of the fastest things on the street.
