As many of you already know i am doing a 5.4 swap in my 99 GT. I just spoke with Terry and Bob at Street Lethal Performance about having them assemble at the very least a built short block for me. I will be going with 4V heads on this motor and i want to build a bullet proof motor that i can eventually put an F1A kit onto sometime in the next year. so far we discussed some options for forged internals and even tossed around the idea of boring it over .20. If anyone has any type of suggestions, experiences, or comments im all ears. Im looking to get this done sometime next month.

^not what im looking for.

i want to know what everyone thinks as far as rods, pistons, crank, etc. I already know that im using stock navigator heads and the Sullivan Performance 5.4 4v intake manifold.

actually most 5.4's have cast crank's (only very early one's got forged crank's) but the forged crank is still avalible new (got mine for 400, new). I'll be using Manley rods & pistons.

im pretty sure they had forged cranks because when i had my crank out and had the cylinders honed and the crank micked he said it was a forged piece. i thought that it was the other way around, oh well i guess. i still got a forged crank and thats all that matters :D

my budget for this swap stands at about 7k$. dream up some way of spending that cash as effectively as possible while maintaining the following:

5.4 4V swap(i can already hear voices saying "get a termi motor", "just buy a procharger")
forged internals
included parts for ease of installation would be nice

no room for LT headers. head work is retarded to do on a 4V and too expensive. vortech cant touch a F1A procharger.
i have navi block, crank, rods, pistons, bare 4v heads, and most anything off this motor. 2000 navi 5.4 4v. If you want any of it let me know! Bare 4v heads and crank would save you some money. Maybe someone else will let us know if the crank is forged or is cast?
stock crank is not forged. what kind of internals do you have?
I can get the Svt GT500 shortblock for 2700 shipped....Try again :D

Ford GT cams = $500
Ford GT Heads = $2000

Then the rest is gonna be tied up in fuel system intake etc etc
is the GT500 block aluminum? i know the Ford GT is. what is the difference in the heads? i believe they are the same. if thats the case i would be better off building my own short block and using better parts than those used by Ford.

stock internals.... I tore the motor down as i was thinking about doing something with it but im just not really into it anymore. so i have an entire 5.4 4v motor out of a 2000 navigator tore down.
 
#23 ·
ill get back to you about the block or anything else i could use.
what do u mean no room?
there is no room for LTs... they just will not fit. a set for a 2V 5.4 mustang swap cost around 1,200$ and arent even worth the hassle. a 4V set would be entirely custom and id end up having about 4,000$ tied up in headers. all for what??? an extra 10HP and trouble accessing things like trans and starter? no thanks.
 
#22 ·
its gonna be tough getting lts in there but its possible..
go with all manley products, speed pro rings and main bearings, clevite rod bearings..
i have around 1300 in my forged bottom end (minus the machine work). unless ur wanting to puch over 650 the keep the cast crank.. its up too u on that one.. but u can find them pretty cheap nowa days tho
 
#25 ·
no your stupid quiksilver. longtubes on a 2v provide something like 20hp/tq and i can only imagine what they would do on a 4v. as far as cost would be concerned though i agree with everyone there that it would be rediculous. i cannot comment on the space issue for long tubes and the 4v.
 
#28 ·
your fantasizing. you say how awesome they'd be yet you agreed that its near impossible to fit them. i dont disagree that theyd be badass. i have a set on my car now and love them, but be practical. they dont exhist, they would cost a ton to make, and they dont have much of a benefit. ill get a nice set of shorties and be done with it.
4000$ for headers???? please show me these headers that cost 4grand!!!
there are headers made for ppl who do this swap.. they are 800$ quite a bit away from 4grand eh?? :eek:
i know the guy who has been spending months custom making the headers to fit for the 5.4 2V swap. he just finished them and they cost $1,200 a pair. however the first set made that the jig was based off of to make every other set cost about $5,000 just to build. retry after retry after retry with parts trying to get them to fit plus hours upon hours of labor trying to fab them up correctly really adds up. As far as i know there is no set for the 4V swap available for purchase. That means that i would have to get involved in the same thing that the guy i know who made the first 2V set got himself into. and it would cost me thousands.
Headers on a n/a have big gains but not st much on a fi car. there are still gains but nothing like on a n/a car
EXACTLY!!! remember, gentlemen. i am procharging this thing.

"i dont disagree that theyd be badass. i have a set on my car now and love them, but be practical. they dont exhist, they would cost a ton to make, and they dont have much of a benefit. ill get a nice set of shorties and be done with it." quote quiksilver225



wow you really do show your a complete idiot in this paragraph right here. you contradict yourself in the SAME paragraph. you say they dont make any gains are you freaking kidding me 20hp/20tq on N/A 5.4. are you high? can you imagine the gains with FI or 4v. you really need to just go back to your hole and stay there.
 
#35 ·
Spending 1200+ on a 1000 hp car to gain 20hp. . meh ill pass.
I'll say it again. You will NOT see big gains from headers on a fi car.
 
#31 ·
time out! why dont you do me a favor and just **** off. im looking for real opinions here from people who actually could give me some practical and more importantly POSSIBLE ideas. it would be much appreciated if you could just go away. thanks for your time!
 
#32 ·
i gave you possibilites. not my fault if you ignored them, go to the first page and check it out. ya know for someone who KNOWS so much about the 5.4 it puzzles me why youd be asking questions about it.
 
#33 · (Edited)
im just brainstorming here. maybe someone will throw something out there that i havent yet considered. and your contribution was to tell me to stick with the stock "forged" crank. meanwhile, back on earth, the stock cranks are NOT forged unless you get and old ass motor that doesnt have PI heads. just stop digging yourself deeper. you come around, present everyone with false information then proceed to tell me that i am the stupid one. get real.
 
#34 ·
this thread got way off track lol. i bet it would cost a lot for 4v headers and the first set did cost like $4000 if i remember correctly. either way, i would get everything done the way u want it and then down the road if u wanted to add headers u could (if they ever get made).
 
#39 ·
ya, tell me about it. this dickhead showed up and ****ed everything up. he cant manage to shut his ignorant mouth.
 
#36 · (Edited)
wow you cant even find the statement where you say they dont make power and then the next sentence you contyinue to say they make good power? that is fail right there. here let me help you "i dont dissagree theyd be badass. they dont have much of a benefit" are you referring to the sound because if you got long tube headers for the sound alone then your retarded

as far as a forged crankshaft yea your right they dont have forged, i was mistaken there. however the crankshafts they DO have can take some crazy amounts of power (like 700hp) so i assumed they were forged. does it matter if i was wrong about the technicality of it being forged or cast when it can hold that much power? no, so just quit your whining.
 
#37 ·
longtubes on a FI car are no different than a nice set of shorties. on a 5.4 swap they are for cool factor only.

has it sunk in yet that there are NO SUCH headers for the 5.4 4V swap?! have you managed to understand that yet??? here, one more time:

THEY DONT ****ING MAKE LONGTUBES THAT WILL FIT WITH THE 5.4 4V SWAP

did you get that? do you copy??? come in, zig... zig, come in.... do you copy that last transmission???
 
#41 ·
nope. first i was gonna build it myself, but with school im just gonna save myself the time and have Street Lethal Performance in New Castle, pa do the short block for me. Thats what this thread is for. Brainstorming ideas as far as parts go for said short block
 
#42 ·
alright then you cant say crap AT ALL. your knowledge has just been discredited simply because your just bullshitting. i DO have a motor and am swapping and know my **** so why not just keep your words to yourself until you get your hands dirty. great thanks ;)
