right out of the box

just polished

test fit

 

Hey guys,

I've been contemplating this swap since I blew my other motor up over a year ago. I've finally mustered up some cash and picked up a 5.4L long block for $650 and picked up adapter plates, an oil pump, new clutch kit and resurfaced flywheel, headbolts and k member kit from UPR (after realizing I coudn't just swap the k member and had to buy coilovers, CC plates and A-Arms =/) So my question is WITH THE K MEMBER KIT, will my BBK L/Ts from my 4.6 fit? or fit with slight modification? I don't want to buy a set of stock logs since I got rid of mine 3 years ago. I would also have to buy a new midpipe, bc mine is for L/Ts... Anything else I'm missing? I'm not looking for huge numbers; Opportunity presented itself to set myself apart from other GTs, so I decided to take advantage of and and attempt the 5.4L swap. Thanks in advance

 

Update: Got my heads swapped over to the 5.4 yesterday along with the new oil pump and the water pump from my 4.6. I also got the 4.6 intake mounted via bandaid plates, which I am not going to recommend to ANYONE. These things are garbage and if I didn't need to get this car running in some fashion, I would send back these plates with a nasty letter. There's literally 1/4" - 3/8" overlap in some places. Today after work, I'm going to get the oil pans swapped and slap the valve covers on and call it ready to go. I still need an answer on exhaust. With the tubular front suspension swap, does this allow enough header clearance for BBK l/ts?

 

I'm pretty sure the steering shaft is going to be the problem with the headers fitting,along with a few other areas.

 

Ahh...that would make sense. BBK had to notch those headers for that on the 4.6 so an extra inch of width would definitely mess with steering. Well I guess I'll just track down some stock logs for the time being. I swapped my oil pan and pickup tube over today and took the truck exhaust off, so I'm getting close to putting it in. Here's what it looks like so far:



I do have a question about the alternator. Well I'll just post the picture:



Is this supposed to set off? Is it going to affect anything when there's tension on the belt?

 

Finally finished my crossover up. I'll be assembling everything very soon.

 

Question:
I've got a 5.4DOHC from an 00 Navi in my 98 GT, But I had to use 98 Cobra Valve Covers which have an angled driverside edge to provide room for the hydrobooster with the new deck height. The valve covers that came with the Navi didnt fit because of this. My question is, I want to covert to COP, but I dont know if they make a COP compatible valve cover that has this angled edge so it will clear the hydrobooster with the new deck height....
Thoughts?

 

alright guys. been a while since ive posted an update. just wanted to say welcome to those that are starting their swap and great job on progress made by everyone!
got an update of my own and could use some help. I ordered a block and crank and should be here in about a week or so.
heads, sticking with 2v, what would yall say to try and find that wont cost a fortune.
cams, and pistons... would like to have around 10- 10.5:1. i want a good cam for a DD but still has a nice decent lope to it. i understand that running bigger cams changes your CR. so im asking for yalls help and opinions on it.

Edit: I am also going to have the cylinders bored 20 over.

 

I've read that some people had to turn the hydrobooster or something. I'm not really sure yet. I'll let you know how mine fits when I get it in there. I've got COP valve covers.

 

If your in an SN95 and still have stock ignition coil pack style then do yourself a favor and get some 96-98 cobra valve covers. IMO.

 

Just got in my balanced crank, ARP headstuds, and head gaskets. I wanna get started so bad but I have to finish up a lot of homework or I'll never get it done.

 

Hey all. Nice to see more dohc'ers goin for it. I'm doin another swap I'm puttin an auto behind mine in my cobra.
R3D, can you do a sim for me to get a decent figure of what stall speed I should choose? My specs are b headed 5.4 with throttle body, cai, and exhaust. Also gonna have a set of 4.10s before long didn't know if that mattered or not but thought id through that out there. Also gonna be running a manual valve body in the trans and the trans is the 4r70w.
The tc is the last thing I need to get this thing in in my car. I have the stock one which is rated at 2400 but don't think that will be enough and make me happy I've heard mod motors like stall.

 

I started piecing together a parts list for my fuel system plumbing. I already have the hose end that goes from my sump. Running a -10 line to the filters and pump, then -8 to a y-block to the rails and then to the FPR. then -6 back to the tank. Anyone wanna help me piece together a complete parts list for this? This is about the only thing that's been bugging me since the beginning of this build.

 

Don't you have a boss intake....too? Lol

 

Yea. I had to get creative with my fuel rail brackets.

 

i got a set of .050" over pistons but my block is standard bore. would it be worth it to bore it the .050" to make the pistons work or what? pros? cons?

 

I hope birdman or illwill step up and take the lead, otherwise i'd predict bad things for this thread.
"I want my" $#@% "2012 Boss." hahahaha, lol.

sorry been out for a while guys... been busy building a new business. Finally got that web site up and running so now I can visit a bit. If you wanna see what I built, check out www.sportsmanmanps.com

sohcout: your pipes won't work period. Get new exhaust.

Joey: MHS 3.5 5.4 cam or a Hitech Stage 3 or a Comp xe278

JohnnySVT: need cam spec for that. Right now a 2400 is fine with stock cams.

jarryd: aeromotive makes that exact thing as a kit. Check the lethal performance web page... IIRC they offer the kit.

zigbig: .050 is taking the modular bore too far. I think you'll have heat problems if you run it really hard like you would a mustang.

ibanez: yeah... car is gone. I have the shell and the motor and tranny.

Any of you want my motor and tranny complete together I'll let you have them for 2800 shipped as a set. that's with my heads and cams and flywheel but no clutch. No intake. Oil pan included.

I'm selling everything else from the carcass cheap. If you want spare parts, LMK. For you guys I'll take a hit on price but you have to make it worth removing whatever you want from it.

 

from what i understand if i even want to take it to .050" over i would have to resleeve it and thats just not happening. r3dn3ck do you have any ideas as what i should do now? i obviously cant use the pistons at all but i might want to try to reuse the rods? i dont know and im kind of at a loss as of right now so suggestions would be oh so helpful

 

re-use the rods if they're undamaged. Use .020 over pistons if you can. buy my engine if you can.

 

the block has already been honed so .020" would still require me to bore it. would it be worth it to grab a set of forged pistons or just go with stock if possible? cant swing $2800 for a block man, sorry. what should i do with the pistons that are .050" over?

 

Guys I'm am considering doing a 5.4 swap in my V6. I am sure the info is already in this thread but I don't really want to look through all 300 pages to find it and I'm sure some of the info is now outdated.

What I am trying to find out is what intakes are currently available for both 2v and 4v 5.4. I appreciate any help.

 

I'll take the 4V part of the question, your intake choice will drastically effect the performance of your engine, but thats another thread all together if you want to know (and if you got 4V, you'll want to know):
1. The stock navi intake works... its just 26" tall or something so it will require cutting a rather large hole in the hood and being proud of the preying mantis Lincoln calls an intake. (free - if it came with your engine.. I'd suggest trying it out if you can without the hood on the car, just to get a benchmark of torque)
2. Sullivan performance's intake, you can still see it at their website but its been discontinued so their rare (i've got one, soon to be for sale as i'm moving to 3) they originally sold for about $600?, but now sell for 2x that.
3. Australian car - Falcon used the 5.4dohc in some models, the engine was called the Boss 260 or 290, (depending on cam and heads i think) and that intake fits on the navi engine if you can find one, and have it fabbed (intake port is on drivers side instead of passangers side). I've got one i'm modding i'd be happy to answer any questions i can... because thats what Forums are for! There are other options than modifying it but they all come with their unique areas of concern.... and price tag This intake alone, + shipping from Oz will cost you round a grand.
a. look up BPT Motorsport. They sell some parts for this too. They have a guy here in the US they use for sales from the states. They offer a (i dont think i'm supposed to tell, but theres a chance i'm wrong here) they sell a terminator Super charger intake stretched out to fit a 5.4. Its also around a grand. Good idea though..
b. they sell a cobra r style upper for the boss also... birdman941 told me he could make one of those too (just to be fair)
4. you could look up Birdman941, he has a pricey "kit" that includes a modified boss intake (from 3 above) and he includes some other ford parts you'll need to make it work. Something around or just under $3k... (if i may be so bold to post that). But dont bother him trying to figure out his trade secrets... he wont tell.
5. mmr makes a hacked up short runner intake (i've heard is not very good at all) but its an option. Its the navi lower with a box on top. ($$700). They also sell a custom sheet metal intake for about $2800, which is about the price for another company like Hogans to custom make one.
6. Reichard Racing makes 5.4 4V to 4.6 4V adapter plates for about $300. They'll allow you to use:
a. the 99-01 cobra intake
b. the 03-04 mach 1 intake
c. the 03-04 terminator intake with supercharger sitting on top... (i like this idea.. but backed out at the last min.)
7. Custom sheet metal intake, see above ~$3k.
- - if i think of more later...- -

 

I'd love to pick up that cobra blower intake. I haven't been able to get much out of that company, I've emailed them and the US rep doesn't ever seem to have many answers. I'll figure out some things.

Having the t/b on the drivers side isnt that big of a deal, just gonna make the turn with the throttle cable, it will still work. I'm doing mine that way, a test fit showed it still working.

 

Just wanted to give you guys an update on my build/budget so far. I have a few more parts to gather but getting closer. I think I might make it under my budgeted cost with the resell of my stock 4.6 shortblock (teskid and cobra crank).

Block: $50
4V timing cover: 150$
Rods (manley H's to boot w/ arp bolts): $415
Probe 2618 flat tops: $360
Forged crank: $110
arp main studs: $113
Intake: $150 (labor to weld it)

Total so far: $1,238

So I have $1,762 left to spend on gaskets, rings, bearings, chains and guides, machine work, and cams. I figure the bulk will be the cams but I found a few cams on svtp for sale between 700-850. They were pretty agressive. I called around for machine work and got quoted $505 for bore/hone/clean/pressure test.

Still undecided on cam specs though. I want peak to be around 6400 so I don't really care if I loose any down low. It'll be gobs more than I have with the 4.6 so its a win win.

 

I can't get the rod bolts open so I can install them on my crank. WTF? It's the ARP bolts but they wont come loose for anything.

 

Many thanks. This post is a huge help. I am still undecided as to weather I want to go 2v or 4v. I am doing my research now so that I can start looking for the good deals

Has anyone tried the 2v Trick Flow intake with adapter plates yet. The Trick Flow heads, cams, and intake recently made 460hp and 430 Ft lb on a 5.0. I bet it would make close to 500hp on a 5.4 with the plates.

 

Plates are crap! They will definitely restrict the power you get out of a set up like that. You would be better off getting the HPS manifold

 

Thanks for the heads up. I didn't realize the plates were that bad.

 

Hey guys, I havent posted here much anymore. Im now selling my entire 5.4 tork tech kit along with my posi ported blower. Im selling everything you need minus injectors and pumps, that means the SCT BA2400 is going as well. Send me either an email at pvt_ortiz@yahoo.com and I will get back at you as soon as possible.
