dont know if there are any MAJOR issues but the reality (as stated previously) is there is twice as much valve train parts to buy, harder to tune (or should I say more to tuning), no room in eng. compartment, etc, etc. I guess it all comes down to what you want, but if your looking for huge numbers your not getting them n/a anyway, you'll need big boost & now your back to square one cause once boosted the 2v vs. 4v thing isnt quite as important as the over-all effecency of the combo. case in point there are 2.3 4cyl. turbo cars in the 8's.

Dont meand to hijack, but i think this is relevant to the Swap, does the 4V add any more noticeable wieght? And Im just curious, and does anyone know how much the 5.4 2v can handle before you need to get a better block. Im getting a 5.4 out of a 2003 F250 SuperDuty short block for $150, and i would like to build it, Basically how much can these 5.4 Blocks take?

[Silver281gt]

just put half down on my 5.4 2v.. Complete i am picking it up for 400.. Ill have it in about 2 1/2 weeks.. I think its an 01 which would mean its a P.I motor right? If so do I not need to swap my P.I heads and stuff over to it??? Just the accesries?

[330CubeGt]

Yes its a PI


Damn at this Rate Everyone will have a 5.4 swapped Mustangs

[Silver281gt]

Hey 330cube.. Since its a P.I. can I just drop it in besides swapping the intake over.. Oh and I have to swapthe oil pans also right?

[quiksilver225]

honestly all it really came down to was the realization that even at getting a much better platform in the 2v 5.4L engine and building an awesome car i would still be wondering what it would be like had i gone 4V. what if i did the extra work? would it have bee worth it? how much faster would i have been? these are questions that i dont wanna be askig myself. ill go insane questioning myself.

well after being around racecars, hot rods, & some 4x4's thrown in for balance, for over 40 yrs & building my own for 30 or so, the one thing I've learned above all else is no matter what you do you'll be second guessing yourself (could have, should have, would have). bottom line...........build what you can afford & go have fun with it. oh & by the way since your from Pgh also, the tracks open (PRP) when we gonna see you up there?

[Garhfer]

If you're gonna go 5.4 at least go 4v as well and get the most ya can, either way it's gonna be a hassle but at least get the most ya can for all the hell you're gonna go through...

just check their schedule on their web site, I'm up there every point's day & occasional t&t. I have the spot at the top of the street lane's next to the bathroom (just look for the casper sign's). stop up sometime, alway's a bunch of mustang/ford guy's hanging around (oh yeah & 1 Nova )

That was my goal 3 years ago. Glad to see someone finally figured it out. Gladder yet it was you. There's no reason to be limited on displacement when there's a solution ready to go.

For the most part. pop into my mustangboards thread and you'll find the little things numerous times. oil pan, dip-stick & tube, oil pickup tube, sensors, etc...

Are you using a HPS intake or plates?

preach it man, preach it.

[quiksilver225]

alright. its coming close to time to buy things. i need a detailed list of parts, part number would be great and sites/locations to buy from would be great too. ...shopping list. a FINAL shopping list that is.

[r3dn3ck]

4v swap parts, 5.4 block, MM k-member spacers (1/2"), cobra shorty headers, figure out your intake manifold, injectors, fuel pump, tuner, cowl hood, lots of money since you want the 4v swap. 2v is really inexpensive.

haha, u really do hate the 4V idea dont you?... i fail to see the added expenses. especially if i get a complete navi motor which can be done for less than 2k. have the tuner, no need for injectors on a complete motor, headers for 250, pump intake and hood for 1200... sell my motor to some poor bastard will thicker(better sounding) oil for 400 puts me at 3,050. i can live with that. oops. spacer add 100. and im sure ill spend an addition 500 on misc crap. but u cant talk me out of the 4V motors power and the opportunity to have the baddest most original mustang in SW pennsylvania for 4,000... wierd how by the time i finished typing up this response i can now see the added expenses i claimed to miss five minutes ago. lol. but i can live with them. i think they are justified. anything else? wire extensions?

[interceptor999]

This thread is full of win, Theres no talk of tuners though, Isn't the stock limiter about 600 or so rpm too high for a stock PI 5.4?

I don't hate the 4v. I don't want to talk you out of it. I have a bias and I'm not shy or coy about it. I have an immense amount of respect for the power a 4v 5.4 capable of (I've even driven the 00' R a few times). I also know that the intake is a costly issue that I don't think you have had the opportunity to research fully. I'll take that on in PM's with you if you like and we can find you a solution that works for you. What I don't want is for you to take on this swap and get frustrated and quit as many who've started 4v swaps have (mostly due to cost).

Your cost estimates are optimistic but not unlikely if you shop carefully.

You'd better get 36lb injectors with stock cams, 39-42lb with hotter cams. You'll also want to grab an Aviator fuel pump.

6000 rpm is entirely possible with a 5.4. With stock heads you're not going to get much beyond 5300rpm before the power curve leans over heads south. Port them out really well and you can make it to 5800. After that, there are head flow issues for sure.

FWIW, Al Papito (Boss330) runs his 4v motors up to 8k+. Piston speeds do get very high above 6000 and honestly a 2v (with Ford cast heads, not TFS's new ones) is leaning over around 6K. With the new TFS heads I'm hoping I can spin 6500-7k before the curves lean over. Looking to eventually be putting ~390 or so to the tires.

The tune is a standard mustang tune with a couple scalars changed. I tuned my own from a Amazon Racing 4.6 base tune with my SCT Pro-Racer kit then had Mark Olson polish it up for me. The stock tune will run a stock motor but they tend to run nasty rich.

[quiksilver225]

glad to discuss the intake over PMs with you. so far it seems the sullivan is the best choice. and with my SCT livewire it seems the tuning shouldnt much of an issue.

[theford302]

u ever checked ur plugs 4 the ticking noise from the very first post? that ticking has come about a few times in my car and i started saving 4 a new motor until it finally blew 3 diff ones out my car just rolled over 200 thousand miles and i can honestly say it has had the hell runn outa it!!these cars are amazing!

[theford302]

and by the way i have a 2v out a super crew that when mine finally gives up i will be swapping in and personally i can't wait. what i was to have spent one a rebuild i am gona put into cams and the nick nacks it takes to make it work and then mine will be unique

[quiksilver225]

sounds cool. frankly, i dont give a damn what the ticking sound is anymore. im so dead set on swapping at this point that i might as well not have a motor in the bay at all right now. thanks for the input anyways. ill check the plugs when i pull it and let u know what i find. im pretty damn sure its a bearing though. got under it and put a screwdriver against the pan and against my ear(make shift stethoscope) and it sounds like a bearing.
