I am trying to gather a list of components required to swap a 5.4 into my 03 gt.
I know the heads and cams are the same.

So here is what I know I need to purchase.

5.4 block
5.4 intake manifold complete with injectors and full rail.

But what I don't know is will I need to change the flywheel?
Some electrical components will need to be lenghtened/shortened
What about accessory brackets? and locations?

And I know it's going to need to be tuned.

Also what year blocks should I look for? I was thinking 99 and up.

2v or 4v??

If its a 4v you have a few different intake choices, 2v your kind of limited right now...

Are you looking to buy a complete motor or are you going to have one assembled?

From your orig. post I was guessing you mean a 2v - easiest way to do the intake would be to just get spacers from livernois (others make them too) and you can still use your stock intake.

2V I looked into a 4V navi upgrade but everything is three times more for the 4v stuff.

I have the room for the 5.4 intake under my hood.

Which one flows better?

Why not just go to a 4V 281??? It will make more power than a 2V 5.4...

The truck intake wont get you much power in the rpms I think you would be better off using the mustang intake with the spacers.

Its always cool to be different too though....but I would do the 5.4 only with either good head cam work/or a healthy shot of the juice.

The 5.42v would probably be a FUN street car with the extra low end power that he will have!

I would shoot a 150 NX shot at it for the track and see what happens. 5.42v complete motors can be had pretty cheap - basically just swap intakes and drop it in - some exhaust work may need to be done because of the raised height on the 5.4, but I can't see that being an issue...

I can't find a resonably priced 4 valve, plus the swap is much more involved from what I have read. I also think the future benefits of the 5.4 are higher than the 4.6.

I think it is a great winter project! If you need help setting up the heads let me know - maybe I could swing by for a day and give ya a hand.

The 4.6 4v swap is amazingly straight forward...the 5.4 4v is much more involved though....

You can get complete motors accessories and all for around $1000 on ebay.

I would leave everthing stock this coming year a probably look at ported heads, cams, and juice next winter.

I talked to Marv he is going to "massage" the exhaust to fit and tune it.

The tune would be much more of an issue if you were switching to a 4v (if you wanted it done locally) also. Going to a 5.4 2v the tune is pretty straight forward.

From wht I understand you can run the 4.6 tune but it is going to be either 19% rich/lean depending on who's talking.

The reason I am asking all this stuf is because you read one thing on one site and another thing on another site its a little confusing....I just want to make sure I do this right the first time.....

No, no, no, not comparing.....just using as an example. If a pro stock racer can ask for spots than I can too! :thumbs_up

Dan did this swap and he suggested a 4V to the guy who asked about it...

I didn't take it as you peeing in my wheels.

I still plan on doing the 5.4 swap...it's different. And what everyone has said is that it would be a fun, torquy street car, which is what I want.

What's the weight difference between these two motors, just wondering how much more weight this places over the front wheel? When going from a 302 to a 351 it's like 100 Lbs...
I'm guessing it's not that much between a 4.6 and a 5.4

Want Notch

11-12-2005, 03:34 PM

I have heard anywhere form 22-55 pounds.

Tubular k-member, a-arms and coil-overs would negate that weight gain easily! :D

I guess I figured since Eric has done the 4V swap... He'd perhaps agree...

Look up Dan Simons on The Corral, his name is TurboX2 or something like that. He did a 5.4 swap and had to fabricate a spacer and such, he has a whole writeup on this swap someplace... He lives up in the Twin Cities...

I do agree with you Greg, 4.6 4v would make more power, more easily.

What spacer did he have to fab? Intake spacers are made by a number of companies now. There are a few who have done the 5.4 2v swap - it really shouldn't be a big deal to do...

I actually like the way the 5.4 intake looks....plus I don't think is plastic so I would proably use the stock one.

I agree that the 4.6 4v will make more power easier but I also think that with some "enhancments" the 5.4 will make a boat load of power n/a.

Well, I would have to go back to some old issues of MMFF, there was actually a feature on Dan and his car and this intake "adapter" he fabricated for the swap. I guess he was one of the first to do it? There should be a writeup somewhere. I believe this was around last X-Mas...

But I want to run the 5.4 intake....I want it to look like a 5.4 I don't care about the sleeper aspect.
