Regarding post (questions) #7860 ... I've often wondered the same things, which is why my project is a bit stalled. I'd like to go 4-V, but I'm wondering if the 2-V route isn't the best to start with, then later go 4-V ... ???

 

i put my b heads on a navi shortblock and had my intake widened by mmr. its not been that difficult of a swap. there are a few things that you need to watch out for if you just get the shortblock, like you'll need a 5.4 4v timing cover, timing chains and guides for 5.4 i found out my 4.6 guides and tensioner arms werent long enough. and you'll need to widen your crossover tube and fuel lines on the back of your fuel rails. also depending on the block you get some of your bolts wont be long enough. two of my transmission bolts were too short and the bottom two bolts on the timing cover were too short because the bosses are thicker on the 5.4 cover than the 4.6. its just little stuff like that that you run into but nothing difficult that you cant overcome. its really a straight forward swap, and can be done cheap even if your goin 4v. after tuning and exhaust work ill only have 3k into mine and its a brand new bottom end. i say go 4v the power is gonna be insane. red told me that in pretty much stock form im gonna be lookin at 350hp and around 400tq to the wheels. and on the zex wet kit i with just a 100 shot i should be at about 460hp and a little over 500 lb ft. im excited shes gettin dropped back in next weekend ive gotta wait til my urethane motor mounts get here next week and shes ready to go the motors already built.

 

I figured i would need new timing components, however i didnt know about the fuel lines and cross over tube. Is there an intake manifold that will just bolt up w/o having to modify my existing intake? Where did you find the navi short block? What transmission are you using? Thanks for the heads up though! Thats good info man . I need a new harness for i am a GT. You lucked out on that part.

 

What 4-V 5.4 engine do you recommend I look for to start with? I ask that because I've seen several things tossed around here and it's like I've returned full-circle in confusion ...

Maybe the question should be asked like this ... (easier I think ... ???)

If I had 1 each of all the production 5.4 engines lined up in front of me (and they were ALL TOTALLY COMPLETE) maybe except for the Shelby and Cobra-R 5.4(s), which complete engine would you suggest I buy if I were to install it in a 2001 Mustang?

Again ... We appreciate your input and advice.

 

That would depend on what route you wanted to go and what you want out of your car.Either way you look at it if you leave the bottom end stock and add a power adder, your limited to about the same RWHP from either of them.If you were going to build the bottom end it won't realy matter which on you get because everything would be changed anyway.You just need to figure out what you want to do and do it.Power can be had from any motor if you have the Funds to do it.And any of the 5.4s would be a good starting point.

 

5.4's only really came in a few configurations in the US other than shelby and cobra R. There were the 2v in PI and NPI and then the 4v was a Navi. Given my druthers I'd probably take any 98-00 block and pop for the TFS heads and HPS intake with some porting for both. It'd make at least the same power as a stock set of C heads and be cheaper.

Keep in mind 4v cams are a grand a set. The complicated valvetrain on the 4v's jacks up the price.

Regardless of the head chosen, they all take up the same amount of room under the hood. 4v's eat into the space in the valley, not the sides. The cam covers are a tad bulkier though.

 

like they said, any 5.4 will work, however, if you go 4v and get a shortblock from a 2v you will have very low compression like around 7.5 to 8. because they have dished pistons and the combustion chamber is bigger on the 4v heads i think. i know its 52cc but not positive what the 2v have.so unless your going to be blown i would search for the bottom end out of a 2000-03 navigator. i got mine from karkraft but i think they are goin or are already gone out of business. i would look for it on www.car-part.com they have almost whatever you need.

as for the intake if you were to use b heads you would have to get a 96-98 cobra intake or one off of a lincoln mark IIV widened. and if you use the c heads your only choice is a sullivan intake or you could have a sheetmetal intake fabbed up for either sets of heads.

o and btw i figured out that the bolts in the bottom corners of the timing cover were long enough they are just too small of a diameter. tranny bolts fit in them so stop by ace and pick up a piece of all thread thats the right size and two nuts so you can still have the stud that you need. if you need anything just ask i dont mind helpin out i know ive asked my fair share of questions on here haha and probably will have some more down the road.

 

does anyone have results with a 5.4 b head engine with a widened intake, or if not widened, which intake?

 

R3D, have you seen the lower pulleys that look like they just bolt onto the crank pulley wtih no bridge?? Am I mistaken or is that how these work?? The lightning/Harley lower is over $500

All of them appear to be for increased boost... which I can't use. I can get the balancer from Kragen for 50 bucks and I already have the lower boost pulley/bracket thing and the upper bridge. It's the 50 bones that I don't have right now that's holding me up.

 

The lower pulley "thing" is over $500 from a dealer. I work at a Ford dealer so I get a discount, but my cost will still be $400. If I can get one of these pulleys for much less, that would be good. I know I will need to watch the boost level also. I don't know how much these are supposed to increase boost.

 

or you could pick one up off ebay or the lightning forums for 65 bucks like I did.

 

I have been searcing eBay and I haven't seen one yet. Let me know if you run across one on the Lightning forums. Set them up with me if you would. Have them email me at horspla91@hotmail.com with the subject of Lightning lower pulley. I have enough on my plate and don't really have time to join another forum. Since you already browse there I figure you could do that for me. Thanks in advance.

 

I just sold one for $5 and the one thats on my car i paied $26 for so there out there for cheap you just have to look.

 

I guess they're out there, I just haven't run across one yet. I was thinking there must be bec. a lot of guys upgrade their lower pulley, but.......I was also thinking that about intercooler heat exchangers and tanks, but I haven't seen any of those, either. If you guys run acrosss any of the above, sent them my way if you would. I just bought a lightning setup last night.

 

i'm looking at a wrecked lightning this weekend. pm me with what you guys need and i'll see whta kind of deal i can get....

black04 only takes cashiers checks and MO's. I almost bought his stuff but that killed the deal.

EDIT:
A little progress has been made. I fixed the defective intercooler tank that I bought from ebay. The seller has some seriously negative feedback. Paypal was no help since it was too old. Such is life. A little JB Weld and a drill bit fixed that mess. It holds a solid 12psi now. Now that that's fixed I'm looking at a crank damper and a pump. We'll see. I might sell horspla my lower boost pulley for 250 bucks and get a stock size one of the things he posted. I like that better.

I finally got the plastic breather tube from my GT motor cut and bent (that was pretty hard) just right so it goes from my inlet to the breather all with hard lines. Got the IAC and PCV almost finished. Made a little more progress on the battery wiring. A couple more weeks of cool weather and I'll finish this bad boy.

 

anyone ready for long tubes FTP is starting on a few sets this week and first deposits get them first.
my car wll be the jig so i'll be there trying to take pics if possible.

 

So how much of a deposit and where do they want it? I would PM him but I doubt he checks it.

 

heres a few pics of my car as she sits right now

 

call them(205-631-3871) and leave a msg or talk to tj himself. dunno on the deposit, hunter and my self paid up front the whole amount to make it easier in the end...

 

starting a contract job today. Should have the money thing fixed soon.

 

A friend is giving me a 5.4 out of a 2005 f-250 superduty, If I´m not wrong, that engine is already a 3valve, can I put my stock (00 gt) heads on it?
