I have a 2002 Ford F150 5.4 Supercharged Harley Davidson Edition Truck that was rolled over and am looking for any advice or help on putting the engine and tranny in a 2005 mustang. First , will it fit? Is it a bolt in or do we need to fabrcate mounts, what about the electrical hookups for the engine.
thank you in advance for any help

It can be done.. With heavy modification. The engine is going to be so heavy you will have to change every suspension part of the car just to hold it. Not to mention you will have to beat up you engine bay to fit that in there. In all honesty it's not worth it. Your better off selling it and buying a supercharger made for the mustang.

^^^^^^^ "Beat up your engine bay to fit that in there"?? I don't think so.
Grabber, you don't know what you're talking about.



OP, the engine will drop right in and that set up won't be a whole lot heavier than the 07/2010 GT500s which had the cast iron block as well...
In fact, it might be lighter since it's SOHC vs DOHC on the Shelby but I don't know for sure.
In any case, not a deal breaker.

Use GT500 mount though but I'm almost sure that the intake is taller on the truck mill, as well as the MAF being on the top of the blower like the Lightnings so you might have hood clearance issue unless you go with a cowl type hood.
You'll have to pay close attention to those details before you pull the trigger on that.
Use GT500 spring rates, no need to redo the whole suspension, lol.
The Shelby used a heavier crossmember to cope with the extra weight but most folks keep the 4.6 in place and reinforce it instead.

The biggest challenge I would see is hooking up all the electronics to make that engine run but since you have the whole truck, use its ECU as well, it will cut out a lot of guessing...
I think it's a cool project. Good luck.

LMAO, this body cars came with a 5.4 4v in the gt500 , which is a great bit bulkier in size that a 5.4 2v. This is not a hard swap.

Like pascal said, the most difficult part is the wiring.. Since you have the truck though you have a lot of donor parts already.. I don't see it being too difficult.. Is it worth it though? IMO it is not if the 05 is a V8.. There is nothing special about the block and you're gaining power that can easily be made by supercharging your 4.6 but sacrificing weight with the heavier 5.4.. I would save that engine for something like a New Edge.. If you have a V6 S197 than go for it..

pascal

Hold on Son... Nothing special? Well then, what's the use for the factory in using the 5.4 in the GT500? I know its got quad cams but still...
I mean, they could have kept the 4.6 and just add a blower.
That 5.4 2V has a lot more potential than the 3V 4.6 IMO because of the already forged internals alone and since there is no replacement for displacement you get 450lbs of torque on that mill with 380hp (01/04) at a conservative 8psi.

IIRC Ford did some unibody changes in 2007 in order to accomdate the Larger 5.4L. It was more than likely to fit the massive 4v heads. But, this being a 2005, I would study up on this and find out exactly what they did. Just to make sure it is feasible before getting half way into your project and discovering there's not enough room between the crossmembers.

I'm pretty sure (not 100%) it wasn't forged.. The 5.4 in the GT500 is completely different, you can't compar the two. That's like comparing the 4.6 from the 03/04 Cobra to the 4.6 from the GT..

pascal

Yeah the Shelby mill is different for sure and I agree with you on the 4.6 comparo.
I just think it's a mistake to underestimate the Lightning engine.
And yes it was forged for sure... Pistons, rods and crank.

TRexGAWD

Hmmm, well I stand corrected on the internals.. I didn't think they were, I'm going to have to look into that. I've tore them apart before and I've seen them fail at relatively low power levels.
