back from the dead, so really a simple swap eh? get a 5.4 motor(preferable 02+), adapter plates, PI 4.6 intake, 8 bolt clutch + flywheel, exhaust and tune? Waht is the deal on the oil pans and crank clearance? Also, the timing covers dont fit on some years? Can anyone clear this up?

5.4 ?????

yep... super duper easy. You don't even really "have" to do a tune on a stock 5.4. It's only when you do heads and cams and such that that becomes truly required. I'd still get a solid tune though or you'll be leaving a good amount of power on the table.
Use a timing cover from a van or expedition if you can, I know those work. I don't know of one that doesn't fit outright actually, but if you check out my sticky at mustangboards.com in the 4.6 tech section you'll have an answer in hours, or you can search thread for myillwillinc's posts on the subject.
Oil pan: 2 baffles are in the front of your stock mustang pan. Give each one a smack with a hammer so they'll clear the crank throw, test fit and spin the motor. Done. It was the single most minor mod.
BTW... get your oil dipstick situated with the engine outside the car. It's a world class m-er f-er otherwise.

R3d...you can use the heads that come on the trucks/van/expeditions and such? Will 4.6 heads bolt up or...i read about puttin comp cams in your mustangboards thread. If you didnt want to swap heads or cams you wouldnt have to?? My main concern would be i dont want it to be a slug like a truck....

No car's, only trucks/vans

I know I had mentioned it earlier in another thread talking with J.R. I'm not sure if you can pass inspection or at least California B.A.R. (I know Cali is strict so they may be an exception) with a truck engine in a car. At least this is how it is with b20 civic swaps and I don't see how this 5.4 would be any different.
It just seems everyone is more concerned with the tech aspects before they even know if it is legal. I'd prefer to find out before I start the swap then after realizing I have a car that I can't legally drive... :dunno:
Someone who knows please chime in as we all know there is no replacement for displacement and from the factory, we are lacking in that area.

The B20 swaps and LSVtecs and what not are visibly different, that's why the referee fails them. They fail on a visual, in Cali it has to be the same model year motor or newer, and originally available in the body.
The 5.4 will have adapter plates between the intake and head, powdercoat them black, and it will look like stock. Now on the exhaust side, you'll want to keep the stock manifolds, and get a really good exhaust shop to mod your factory mid-pipe, so when they look at it, they see 6 cat's and no welds.
Of course, in addition, your tune will need to be spot on, so budget for a dyno session with someone reputable.
On the roller's there's no reason it shouldn't pass.
Legally though, no it is not legal in California, since the 5.4 was never available in the SN95 body. Shelby swaps are legal for S197 owners though...

:TY: J.R
As long as the motor is from the same model year or newer and you retain all the stock emissions equipment for that motor it's entirely legal. Since the modular engines are all the basic evap/pcv/egr/multi-cat setups it's pretty easy to comply legally. Anyone who says it's illegal doesn't know cuz I know for damn sure it's legal if done legally.Red said:I know I had mentioned it earlier in another thread talking with J.R.

Second, it doesn't matter if it's legal. It's almost totally indistinguishable from a 4.6. You'd have to be a mad-dog blue bleedin' mustang guru to notice. Last, it's pretty stupid easy to get a hook-up on smog. Only tards and the lazy can't manage it.
Lrall said:Sorry to ask all the questions, did the 5.4 have NPI and PI heads/cams/intake like the 4.6? If so what years and you said you can use stock heads so you could use the NPI 5.4 heads/cam if you had to?
5.4 went PI in 00'. 99 and earlier are NPI. 4.6 and 5.4 heads are the same heads for our purposes. It doesn't make a damned difference if you use mustang PI heads or truck PI heads or mustang NPI or truck NPI. The only thing that changes is valve covers.
As for what cam... if you bother with a cam, then you should also be bothering with a set of ported heads and longtubes. There's no such thing as a 5.4 mustang that's a slug. They're all spankin' ass fast. Some are really stunningly fast.
DO IT DO IT. the swap is so simple its SICK. Ive read through 40 of the 122 page thread on mustangboards and im impressed. With the expedition being an 03 you would get the beefier block, PI heads, and i dont think you'd need a new timing cover? dont quote me on that though, im still a bit fuzzy.. soo 1200(motor) + 375(adapter plates) + PI intake(??$) + 8 bolt clutch flywheel(depends used/new) and your thereatrainsgt said:I found an 03 5.4L ford expedition engine with 74k for $1200. I'm really considering it.
I'm actually seeing the adapter plates for $200.00 and I already have the PI intake....Will be a pretty inexpensive swap. The only reason I haven't bought the engine is, my transmission is getting some problems and I know that 5.4L is going to speed up the process. I wanted to buy a new engine and a T-56 at the same time so I have to decide if I want to wait and buy both at the same time or go ahead and buy the engine and let it sit in my garage.
I was looking at these.

wonder how they work...
Im going to hold off(i have to until summer anyway) when HPS is coming out with their 5.4 2v intake so no adapter plates are needed, along with long tubes that are being made by a 'big timer' R3d said should provide 40hp/tq. End of march should bring the intake he said.

not bad at all.
the plates on ebay are well made and plenty strong but like all adapters they need a good port match job on them out of the box. I prefer the ebay plates actually to RR. They really fit better IMHO and the gasket they use is much easier to deal with than the wiggle-worm OEM gaskets. Still plates suck as an option when the intake is just a few short weeks away anyway though.
Buy the engine... if you pass up a good runner like that you're plum silly. Let the thing sit around but at least get it in house. Deals are getting harder to find thanks to all the people snapping up the best motors for mustang swaps. My engine sat in my garage for over a year before I got it assembled.
The Longtubes are taking longer than expected due to manpower constraints at the company I'm working with. grrrr.. Anyway, in the meantime use BBK longtubes and have your local exhaust shop mod them. I'll see if I can get an exact description of the mod that's required. Should add about 200-300 bucks to your overall project cost.
As for the tranny... if you put big tq in it from the 5.4 and it's about to quit from the 4.6L whippin... time for another. It'll frag the tranny if it's not in good shape and you get on it hard. Treat this like a blower install. Anything you'd be worried about blowing up with the blower, you can blow up with the tall deck block.
