One additional thing is that the InTech 5.4's and the 2004 5.4's have a forged bottom end. Can you say boost?!?!
I have to be missing something here. This is way too cool.
P.S. - Wikipedia = teh pwnage

You're spoiling my secret plans, groundpounder [8D]
Drop the link to that wikipedia article when you can, if I can confirm that the newer InTech engines really do have a fully forged bottom end, my plan will be coming to fruition MUCH sooner than I had originally anticipated... I was planning on having to drop for forged internals and having to tear the engine down and rebuild it myself (key to saving money ) before dropping it in my stang.

ive been looking into this myself. i know everything should fit pritty good, shorty headers will be needed, but thats no big deal. i would love a 5.4 dohc.

Would it not be cheaper, (and more practical), to run a built dohc 4.6 with high boost? Lighter, higher revs and way more hp than a Lightning 5.4
Keep the 5.4's and 6.8's in the trucks.
Eventually, the added weight will cancel out the added power.

There is no replacement for displacement, but doing a motor swap (to a different engine) probably isn't gonna result in much of a cash savings in the end.
I could be way off base here, but I'm gonna go out on a limb and say in the end the horsepower/dollar ratio isn't gonna be much different than going with a 4.6 build. Either way your gonna need deep pockets.
If your planning on keeping it (the 5.4) stock just forget it. As they stated above, almost everyone I have seen that keeps it near stock nets more torque, but about the same horsepower, and it ends up not being worth it.
If the 5.4 blocks you are talking about are avaliable at all, and not with a massive pricetag, AND they are forged it might be worth it, but I have a feelilng you are gonna end up paying 3k+ if not more for a forged assembly 5.4L out of a lincon ect.

Probably not, because when you say high boost, you're going to have to upgrade the bottom end of the 4.6 at some point, and the 5.4's come with forged bottom ends, plus 50 cubes. Yes, you do have the purchase price of the Triton to begin with, but that is offset by some number by the subsequent sale of the 4.6 that you removed. So no.

This is a tech thread about what it would take, not an opinion thread about whether a person should or shouldn't. Don't get me wrong - I'm not flaming you because of your opinion, Bob, but do you know if the wiring harness from a Triton will plug right into the Mustang's? Because that is my major question right now. Not whether the 2000 Cobra R, the Ford GT supercar, or the new Shelby GT 500 should have had a 4.6 instead of a 5.4

When? the difference is about 50 lbs, which is taken care of by the extra 40 HP and 63 lbs of torque. Before mods. See link to 300HP/365tq engine below.

There is no replacement for displacement, -- BINGO! -- but doing a motor swap (to a different engine) probably isn't gonna result in much of a cash savings in the end.

You can only go as fast as your wallet!! With your ratio calculations, what did you come up with, since you're out there on that limb? Because I don't think you can forge the bottom end of a 4.6 and make it produce 300HP and 365 ft lbs of torque for $1,150 like the link to a Buy It Now auction like at the bottom of this post. NO way. And what if you get $500-600 for your removed engine? It's possible. Then you have spent a net of maybe $600 initially (I'm ignoring labor, fluids, blah blah blah etc) for 40 HP (300 v 260) and 63 lbs of torque (365 v 302). $15 per horse, $9.50 per ft lb and $12.25 per cube. What if you get $800-900 for the 4.6? Or more - $1,150!? That ratio falls and there's NO WAY you're going to forge a 4.6 and mod it to 300 HP for $5-600. All the work invovled in breaking it down, gaskets, blah - you're pulling the engine anyway to do all of that - so that's a wash - and you're always going to be spotting the 5.4 cubes and torque. This is a no brainer if I can get some answers.

That's an opinion, and this is a tech thread. You are starting out with a forged bottom end, 40 more HP (for the engine below), 49 more cubes and 63 more foot pounds of torque. BUT I digress. Do you have the answer to the wiring harness, intake (answered), CAI, A/C and P/S questions? Because if not.....

Ummmm nope. Here is an 04 F-150 engine that comes stock with a completely forged bottom end, 300 HP and a whopping 365 ft lbs of torque. Before mods.
TECH TECH TECH. I'm looking for unequivochal technical anwers to my technical questions. I mean, I'll start a new thread if I need to -- "Is it worth it to swap a 5.4 for a 4.6?" and we can fire away with the opinions. I need the technical ins and outs. Engine management, accessories, bolt ons....
Does anyone know who's done the swap? Someone mentioned it.
