Hi guys, I might be swaping an 4.6 engine in a 2001 Expedition in the near future. I am looking around for junkyard engines and the only thing I am seeing that fits is the 2001-2002 Expedition engine. Is this true? I am fine with swapping over acessories, but I don't want to have to do major work (i.e. rewiring/ adapt to new transmission/ etc.). Are these two years my only options? Thanks for any help.

 

anyone know?

 

well if you have a 2001 it should fit another 2001

 

I understand that. I want to know if other 4.6 block and heads will fit the 01 Expedition. For example.... Does a 4.6 from a mustang have the same block and heads as the 4.6 offered in the 01 Expedition? Or is the bolt pattern on the block for the bell housing different? I am looking to see if I can take a 4.6 from another ford and swap it into an 01 Expedition....I realized the intake manifold and acessories will be different, but as far as block and heads are there any other doners I can use for an 01 Expedition?

 

Double post, sorry.

 

Nearly all of the 4.6 engines have the same bolt patterns for the heads and intakes. There is a difference between the Windsor and the Cleveland built engines that is the number of bolts in the valve/cam cover and also in the front timing cover. The engine or block that you will want to avoid would be the DOHC units used in the FWD Continentals, those have a smaller bell housing and are just totaly incompatible with your needs. With that said, you should be certain of the plant your engine was made in and get a similar engine that was built in the same plant. Way fewer headaches when doing it that way.

 

here is an ebay link eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

they are selling a re maned long block. According to this all of the 4.6 used in the trucks/vans from 99-04 will work. Can any one confirm this? It would make it a lot easier to find a replacement. Again, I really just need to know what long blocks will work, I am fine with swapping everything else.


*edit* Arent all 4.6's in the 01 Expedition from the Romeo plant?

 

I am also researching options on the 4.6L. I own a 98 XLT with the 4.6L. The engine has been great, and I can say I get 18/19 in city and 22+ hwy. But, at 199K miles it is starting to get a bit tired and consuming some oil. So I am researching the topic as well : rebuild vs swap.

I would think the first answer from all would be swap in a 5.4 from a similar year. It should be pretty easy to bolt on I guess. But I think I rather keep my 4.6L and rebuild it with maybe a swap of cam, heads and updates here and there.

I found this great article Ford 4.6 Engine - Junkyard Jewel Ford 4.6l 2v - Engine Build Up - Hot Rod Magazine. I am not going to build a hot rod but sometimes the info that comes in the article can be quite handy.

Right away I find that the post 99 4.6L 2V has better HP and torque than the pre-99 version. That might be an easy swap right there, and pickup 50hp on the move is not bad.

Personally I am not too hung up on keeping the tranny. Mine had problems early (around 50K miles) and thank god for the extended warranty! If that has to go for a newer/better option, so be it.

Anyway, more/any info on 4,6 compatability is very welcome. If I could rebuild a later model 4.6L 4V engine that can go into the expy, I think that would be great. The article claims to free up 160HP. I would go milder : an extra 75 to 100 would be fine with me.

 

OK I'm not sure if this is getting added to the conversation correctly or not bcuz I hit reply & it doesn't simply add your message as you would think apparently somebody thinks this needs a bunch of totally confusing "OPTIONS" displayed in the open instead of putting them in a simple drop down menu you can click IF YOU WANT OR NEED OPTIONS to add a simple Reply??? That's the entire reason I don't use this site very often but anyway hope this makes to be useful???

I'm looking to replace at least the 4.6L block in my 97' F150 4x4 after just having redone the heads but not doing the bottom end due to how good the cylinder walls looked... Unfortunately after running the best it's ever run for about 3 or 4 months it spun a bearing so I'm looking for a used lower mileage 4.6L motor to to use while redoing the bottom end if it didn't get too damaged?

I had the same questions on compatibility & I found most of the info I needed by searching for how to read Ford VIN codes to learn what codes I might be able to use thru the vin n umber so I know I'm at least at something worth looking closer at & then & search the history of Fords Modular engine & this should help anyone get a fair understanding of what other cars/ Trucks, or SUV's may share parts they can use ( https://en.wikipedia.org/wiki/Ford_M...production_car ) The biggest worry I can see is just to make sure your getting the right version of the 4.6L Either the Windsor or Romeo because they have small differences that are version specific like 6 or 8 bolt flywheel flexplate, differences in the heads, cam/ timing chain sets, & valve covers, & crank journals in the bottom end..... Your motor probably has PI heads (Performance improved that I think started in 99- 2000 & is good for about 50HP over the NPI) but you should double check I might be a year or so off? Either way the PI heads are a sound & simple upgrade if your already going that deep in a repair & I wish I'd know the difference when I did mine !
That's about all I have except to say that you'll get the info on how to tell the blocks of the 2 versions apart within those searches too.... Hope that helps anyone who needed that info?

 

What you want to look for is if the 8th digit in your vin is a 6 or a W. Get an engine from a vehicle that matches that vin code. Be aware that in 2003 Expedition used some all aluminium 4.6 engines with the W code, and I believe all Explorers of that area had aluminum W code 4.6 engines.

 

Yes, I have 2002 Expedition but MY2003 (II gen.) and I have 4,6 aluminum Romeo engine.

 

I’m looking at doing an engine swap on a 2004 ford expedition 5.4 with a 1994-1997 ford thunderbird 4.6 is there any problems with this swap?

 

I can think of at least one. If you have anything less than 3.73 gears, you will be totally disappointed with the power.

I had a 2003 Expedition 4x4 with a 4.6 and 3.73s. I was underwhelming to say the least. It was good on flat ground, but struggled in the hills of NC.
