My brother has an 04 single cab stx with a 4.6 an is contemplating doing a swap with a new 5.0 coyote, is this possible

 

it's gonna be one hell of a wiring mess... i think the 5.0 has a motor controller, and tranny controller, wheras the 4.6 has one PCM. Idk, im not sure. ive seen it done in a 5 speed mustang.

 

anything is possible with enough

 

Yes

Find a totalled 2011 F150 with everything and start swapping things over. Be prepared to do some custom fitting though!

 

In "the good old days" it was possible to do something like this if you were half way handy and could fabricate things like motor mounts, etc. These days however, there's so much electronic stuff that needs to be properly integrated that it's almost impossible to do. But, as others have said, anything can be done for cubic bucks.

My advice to your brother would be to save his money for a newer truck with the 5.0 already in it. First, it's going to be cheaper and more reliable. Second, you won't have a hacked up truck that sort of runs to try to sell someday.

 

Would swapping over to a 5.4 3v be doable

 

Sure it can be done.
Going to all the truck shows out here in Texas, you see trucks with INSANE & CRAZY motor swaps that are running 100% with no problem and I think it's pretty damn cool.
Like they all said above, with the $$$$, it's possible.

And yea, the 5.4 3V would be possible, but with the Coyote & new motors out, if you're going to spend the $$$, go ahead and go for the best bang for your buck, which IMO is either the 5.0 or the 6.2 which would be BADA** in a Single Cab Ford, but alot of fabrication, wiring & DINERO needed for any swap! 5.4 3Vs are just not even in comparison with the new lineup, at all.

 

This guy swapped a 5.0 in place of his 4.6 in a Sport Trac Adrenalin:

I freaking LOVE that. If it can be done in a L, it could be done in a Single Cab 04!

 

From what I understand, the swap with the least expense and headache is to a 5.4 2v. We have a member here, IntRiniTy, that has done it. Your best option for HP/$ would just be to turbo the 4.6L. I wouldn't raise the boost as high as these guys did with a stock motor, but should give you an idea of what needs to be done. http://www.hotrod.com/techarticles/e...8/viewall.html

 

is there a problem with the old engine or does your brother just have more time & money then he has sense?

If the old engine is in working order, why not just trade it in for a truck with a bigger engine?

 

If the truck is paid for, the loss on a trade in, and a new truck depreciation would be more than the swap would cost

 

yea truck is paid off for, that adrenaline coyote build is pretty sick with the a six speed manual tranny, i love those little trucks i can only imagine what its like with the coyote in there, and we are going for the cool factor in his truck, he is doing a full saleen body kit on it so the truck is gonna look fast but that 4.6 is anything but it ran a best 16.4 pass at the drag strip with a k&n cold air intake, and a flowmaster exhaust, with a superchips canned tune in it, after he is done with the exterior he is looking into either swaping the 4.6 with a 5.4lt 3V with either running a saleen or whipple blower on it, or trying to do a coyote swap in there which would be very cool, costly but cool

 

The 5.4 3v swap will be pricey as well from what I understand. Forced induction of some type on the 4.6L is going to be the cheapest option and can still get respectable numbers.
