does the 5.4 engine fit in a 98-04 stang?

yeah you can drop one in and yes people have done it..mm&ff actually did this swap...because the guy blew his stock 02 Gt motor with a nice juicing ( 250 shot) so they ran it on the dyno it put down something liek 220 hp and soem crazy thing like 300 torque with just a conical filter..they tuned it and came out with 230 hp and 320 torque....nice number for being totally stock. ccasion1

You have to see how much power you want and see whats the best way to do it. In my case If I would of added a SC I would gained a punny 75hp so I went with an engine swap and I will gain around 100hp and Ihave room for a SC later on.

that one article were they put the 5.4 in that gt, umm they kept the truck intake and it still fit with stock hood..they just had to notch it a bit.. and well it was def. stock when they put it in and dynoed but ... then they did make alterations later on...

5.0& SuperFords installed a stock 5.4, then in a few seperate articles went back and installed different mods, a chip, exhaust, short runner intake, pulleys and then later on cams.

I Probably date myself a little but us older guys came from a school with the rule that there is no replacement for dispacement. I had the privelage of growing up and owning several large cubic inch muscle car's such as 440 6 pak cuda,383 magnum charger,454 stingray and many other's that I wish I had still owned. I like to keep cars n/a for the sleeper effect when the hood is raised and the money savings and reliability. I face a problem many of the rest of you do,my best friends wife can kick my cars butt badly with her STOCK 2002 Trans-Am. I know I'm running a auto and a convert,but my car is only 20 lbs heavier and mine has lower gears and some bolt on's. We took each to the strip and I ran 14.4 at 95 mph vs 13.5 at 105 mph (and the t/a had traction issues that I didn't) We simply have a huge torque and horsepower disadvantage,even worse now with the 05 6.0 litre GTO! Some day I may build a 2000 or newer 5.4 block,bore it 20 over and bump compression up to 9.5 or slightly higher and port heads,install cams and drop it in the stang and it would look stock to most.

good luck cause ,a high horsepower n/a modular motor is gonna cost u... it would be awsome if u got the money and ambition to do it... and i'd love to hear about a stang with a really built 5.4 or w/e.. cause honestly i 'm getting tired of every other stang owner braggin about their new blower... i know the term still exists, but slightly changed.. there is a replacement for dispalcement it's called technology... why do u think a dohc 4.6 will own a 5.0 stock for stock??? smaller motor..
#17
Sorry not trying to argue either...just making a point about the MM&FF article is all. As for a fast Mustang with a built 5.4 go to www.boss330racing.com. Al Pappitto (hell of a nice guy) runs 10.20's with a 520rwhp N/A 5.4. He also built Bob Cosby's motor (4.6DOHC that made 357rwhp N/A) that dominated NMRA Factory Stock class in 04( car has since been sold).

I'm not interested in building a dohc motor for a few reasons 1.doesnt look like stock 01 Gt engine 2. Much greater costs involved in buying the engine to build vs 5.4 2v and the extra costs of camshafts,fuel pumps and computer upgrades and other fitment issues.I do realize the dohc motors both 4.6 and 5.4 litre breath better and can produce more power. I was just thinking though when it comes time to overhaul or replace my 4.6 that I would build a 2v5.4 instead of the 4.6. I believe it would be cheaper and more reliable than stroking the 4.6 and would still have more cubes than the 4.6 strokers out there now. Not trying to provoke any arguments but the 4.6 just lacks the torque of the old 5.0 and the newer 5.4 litre engines and is more noticeable in the automatics than the 5speed cars. I want to stay n/a

I've put a 5.4 DOHC out of an 04 Navigator in my O2 gt with a votech V2-Sq supercharger. Email me if you want pics. douglasogan@hotmail.com

a newer 5.4 out of a navigator would be a nice replacement if you could purchase it resonable. what would a person use for a computer and wiring harness if you went that route? sounds like a lot of work to do that conversion compared to the 2v expedition engine. I do realize theres 40 more hp with the 4v navigator.
#22
Suprisingly, a GT wiring harness and computer can be used to swap in a 5.4 4V. Some modifications and a tune are required, I'll post a link of the nessecary wiring mods. Basically you need to length the wires for the coils and a few sensors.

5.4L motors do fit in the 94-04 Bodies...and will even fit fox bodies with a little modification.
This is one of a few options when going with greater displacement on these Modular motors. A stroker is almost not even an option, as it's scary to see how far the piston comes out of the bottom of the bore. A Big Bore motor is a viable option, however it reduces mating surface area between the cylinder heads and block...and blown head gaskets can become common especially under boosted applications. A Big Bore will make more power than a stroker though.
A 5.4L provides significant displacement increase, and you can go Big Bore on these motors as well. A Stroker on a 5.4L is not possible (read: not smart) though, as the piston speeds would become ridiculous approaching 6,000+rpms.
