One of the vendors here, http://www.vtengines.com does the 5.0 stroker thing.
And they sell the 5.4 Cobra Longblocks for only $9,000.00 Street/Race:):(
So I do my "convert" program and come with 280 cubic inches = 4.6 liter ?
Wow, I should have put one of these in my 32. Much more power in a smaller package.

If someone were really considering this, other than the Lightning engine, the new truck 3V 5.4 would be the way to go. It's got 300 hp and lots more torque - way down low in the rpm range - and it does it with regular gas. If you supercharged that, then you'd be talking! You'd probably need to swap in the transmission to go with it. I don't believe the 4R70/75 would last long with a supercharged 5.4. Maybe not long with a NA 5.4.
 
To do this right would require fabricating new subframes to clear both the engine and transmission.
You would want to put the Lightning Drivetrain into the Marauder, both Engine (w/SC) and Transmission.
You would also need to rework the front suspension to support the added weight without loosing GROUND CLEARANCE... :eek:
And the rear of the car would have to be raised slightly to keep the raked look.

Add to this the need for a custom made hood with either a shaker,
or a lifted center section for clearance, and you should be golden.

Add the Kooks exhaust, and you should retain the Marauder sound.
The headers should fit nicely if the side to side measurements don't change,
and your subframe centers the engine, top to bottom in the same position as the original engine.

All of this is good because you can then go from the 18" wheels we have to a 20" wheel,
have some more tire sizes to choose from, and be able to keep the Marauder's look.

Just don't think about driving it in the snow... ;(

hmmmm....
Sounds like a project for next summer !!!
 
Well if your going to go this far a transmission..

is just a drop in the bucket!! A S/C and is the better bang for
the buck but if money's no object and a big hood scoop doesn't
bother you!

If money was no object....

A Super Charger would be the last thing I invested in.

We've said it many times, and I'll say it again here...

"There is no replacement for displacement"

I would rather spend my money shoe horning the largest engine I could find into the Marauder,
couple it with the best bullet proof transmission that could handle the power,
and then, and only then, if I still wasn't satisfied, look at Forced Induction.

If I want the cheapest, fastest, and shortest route to power,
then conservatively adding Forced Induction to the stock engine is the way to go.

Done right, the hood scoop will only add 2" to the top of the hood.
I have some ideas and they all complement the Marauder nicely,
without loosing the Marauder look.

But if money was no object.... :D

Why not share them? Next winter I hope to put a new hood on LK.

I agree totally. If money were no object, then go real "old school" and drop in a 427 side-oiler like the original! That would get you rolling down the road at a good clip. Change the hood and I bet it would fit.
 
First to Sgt.Mac the 4.6 and 5.4 block are in no way the same,the 5.4 has a taller deck hieght. The 5.4 at10.079 to the 4.6 at 8.937.


With that info a 5.4DOHC would be at least 1.2" taller if you could adapt the stock Marauder intake,but it's the width that makes the swap hard as the engine gets taller it also gets wider.
As the 4.6 sits in my Marauder now I see about an inch of clearence to the A/C box on the right and the Brake booster on the left.The killer may be the windshied wipers though.Look at the rear drivers side of the engine on the firewall note the clearence to the cam cover,in this area the 5.4 will be about 2 inchs taller.


If you have the money stop asking a bunch of internet know nothings,prove us all wroung and just do it.

Then post all that's required,or build an install kit and sell it.

I can't spend that kind of money and have the car down that long.

Best bet,follow BillyGMans advice-SUPERCHARGER!
He has been there and done that.

BTW No off the shelf header will work with a 5.4 because the 5.4 is wider! and taller!

You need to get with some local Marauder owners,or hit a meet and check out how the Kooks headers and DR systems fit,now move them up and out at least an inch and a half on both sides,my kooks will hit the A/c box in about 1 inch up hit the crossmember,steering shaft and maybe the floor.It will all be ugly.

Don't forget the custom tuning required to get all the power from your new set up.


At $6000 the Trilogy is a bargin. That $5000 DOHC 5.4 will cost about $7500 with good headers(custom) and tune,plus modding the A/C box and installing a smaller brake booster.Oh,don't forget that windshiedwiper bracket.

And that assumes your doing the removal and install yourself $0.
A swap at a shop that knows what there doing will add at least $2000-5000 in labor.l


I'm not trying to talk you out of your dream ,but, well....

I worked at a shop that handled this kind of stuff in the early 90's.
We had a guy come in who wanted a 500ci Mustang. So he brought us a nice 89 GT. Crate 500ci/460 from FRPP $$$ and a 4spd GM auto and the adapters required.
He spent over $12000 on all the right parts,plus the car,about $7000 in the day and paid us another $5000 for the install more mods and tuning and guess what?

It only ran high 12's our supercharged 5.0 with stock bottom ends ran low 12's and got much better milage and no overheating. For only about $5000 back then.

Just Supercharge it baby.
If you must blaze your own trail Turbo it.
 
Why is this discussion happening? The motor will not fit, plain and simple. Been here and done this. Steve Babcock and Ned Nuss already provided all the messy sorded details on how it did not work from the go when the concept Marauder was being designed.

The motor simply will not fit without major rework. How much rework? Enough that Steve's team gave up the idea quickly and stayed with the 4.6. A 5.4 in a panther is just not going to be a practical reality.

Mike, beside's Team Ford not being able to do it, don't mean it can't be done, they didn't try hard enough, So ya have to do some cuttin and hackin, a hot rodder will get one in, and I thought I saw one here already from SEMA awhile back and Vortex, an iron FE or a 429-460? the Marauder already weighs too much, those motors are way too heavy at almost 700 lbs., less with alum, parts. Go with the 5.4 from KarKraft, the one with 2 fours and it's own computer. :rasta:

I know this thread is about a 5.4 in a marauder, but...

If we already know we are 2.2 tons of fun [or more depending on the MM driver! ] , what's another 200 pounds between friends?!
:D
I -know- the 460 will fit and with it stroked to 572 (think TWO 4.6's in there!) I'm sure the car won't mind the extra weight. Then put the squeeze to it to get a guaranteed 850 hp. 730 ft./lb torque. It won't get 20mpg, but it would shred any tire you want to put behind it.

It's on my list right now and I've already got the block. When it's done I think I'll slip it into my pickup while waiting for that "just right" MM to come along. ;)

Way cool! I am waiting to see the results!

I'd love to see this get done one day!
 
A friend of mine started to transplant a fairly huge motor into this Mustang. Took it the track and bent the crap out of the frame it had so much torque LOL

WTF are you talking about Lance, when in the hell did I say that?

Getting back to the topic at hand...

The 5.4 and 4.6 share the same block, same bore, just longer rods and different crank offset.

5.4 has lower compression, which is good for supercharging. More torque is good too, but it's not that much more considering the investment.
4.6 heads won't clear the pistons, and 5.4 heads are taller, which changes the "V" shape ever so slightly. The 4.6 intake will not fit this difference.

5.4 intake is where the engine height comes in, it's 1.5" taller than the 4.6.
Not to mention the intake's front facing air induction, a custom intake will be necessary, and expensive.

No flame intended, but I thought the same thing that Lance did when I read your post.
 
Post? Where? What post!


Oh...You mean that crap from LAST year??? Uh gawd...


Got bad 411 early in the game, what are you gonna do...
 
I would personally not change the motor in my marauder...

as it is a limited edition car..I would find an old Interceptor
and do the mods hood,big motor and manual trans...then I wouldn't
be upset if I had to cut something..Hack it and make it fit!!:burnout:
