Have you looked at a DOHC navigator motor and putting some cams and a turbo or blower on it?

 

You might want to check on starter compatability. The GT starter is mounted to the trans. GT blocks used in other applications have to be machined for a starter pocket.

Since this is a mid engined car the blower intake is different, pointing straight to the rear into the firewall of the Super Duty. Look at one here;

Looks like some major surgury to the firewall to get this to work. Of course this is a small amount of cash compared to spending $45,000 on an engine, and another $5000 for parts to make it work.

If your set on a supercharged 5.4 DOHC, Ford sells several varities through FRPP for between $12k to $18.5k along with supporting parts. They have one that puts out 605hp. I'm sure some of the vendors on this forum could help out there. This is a more realistic approach, costing less than half of the GT motor. Even better would be one of the many aftermarket superchargers for the 3V.

Good Luck

 

That wasn't one of my intentions, Although I did have an Idea of putting a 03-04 Cobra engine into it, the only problem is I can only find a aluminum 4.6L 24V DOHC Block, I have also consider the GT500 engine, If I am not mistaken for those of you who are on F150online.com there is a guy putting a gt500 motor into an f-150.

I will definitely figure something out regardless, I haven't ruled out a diesel, but I don't really tow anything so I don't really have a use for diesel at the moment I mean they sound bad *** and all, but its to much for what I need it for. Plus Like I said before as well, I am trying to be unique that's all. I appreciate all your guys inputs.

 

Look into the Lincoln Navigator motors. They are DOHC 5.4

 

And if he doesn't have deep pockets what does it really matter to you? If you think this topic is a waste of time why do you bother reading/responding? What is the harm in dreaming and asking questions? Not sure why it bothers you so much.

Now back to the point of the thread...

 

Because if he doesn't have deep pockets then he needs somebody to give him an idea what those ideas REALLY cost before he's in over his head. Not somebody saying, "Sounds cool! Go for it!"

The latest round of ideas are more grounded in reality. If he didn't eventually get grounded in reality then it would have ended as a waste of time. But that doesn't seem to be the case any longer.

 

OK, I think you should back up a few steps and define your goals a little more realistically.

While it is possible to get a street driven Super Duty into the 10's, I don't think you're going to make it happen with a stock block 5.4L, or even a V-10.You'll grenade the engine trying. It's more realistic with a Power Stroke, but you're going to end up with a truck that is miserable to drive on the street.

So, that leaves us with you wanting to have a supercharged 5.4L 3V V-8. Now, things get easier.

First, find someone that will write you a tune for your engine that will support a supercharger.

Second, order this kit from Ford:

Throw out the tune that comes with the supercharger. It supports the F-150 transmission and won't work with your 5R110W. Get your custom tune downloaded and you're on your way to becoming a tire shredding demon...and you probably just saved about $35,000 dollars and 6 months of shade tree engineering work.

If this isn't enough for you, install a stroker kit and get some cams for your engine, then upgrade your fuel system to support more power and get a tune written to make it all work. You can even get a custom pulley made for the supercharger to crank out more boost, but I recommend starting with the basic kit and building from there.

 

+1 for the cost of a crate GT500 engine you could build a 5.4 from bone stock to 800HP for much less. Most crate engines are the expensive lazy way to build moderate power in the long run.

 

Some of you guys are missing my whole point, I don't wanna use the Stock 5.4L 3V, I have come up with the idea of getting a WS GT Block its only 3-4G for the block, then you figure it will be a few more grand for pistons and connecting rods etc, then I am topping it off with GT Heads which are 1500 a piece, I haven't decided If I want to go with stock GT cams or Comp Cams, I would need to Get either a GT500 Intake Manifold Cobra R manifold or GT manifold to ultilize the S/C

 

But in doing that, you end up with an engine that is designed for a car that tips the scale at around 3000 pounds. It isn't a good match at all for a truck that weighs over twice as much. You won't have the low end torque you need. If you installed cams to boost your low end torque, you now have a mismatched engine, since the heads and intake are designed for higher power band than the cams.

If you are just going for the "way cool" factor, consider that not many people at all can tell the difference between GT heads and stock 3V heads from the Mountaineer 4V heads. Fewer yet will know a GT block from a stock 3V block.

I have 2 classic Pontiac full size cars. One has a 421, the other a 389. 99.9% of the people looking at the engines can't tell the difference. Hell, 95% can't tell the difference between the Pontiac engines and a Chevrolet small block.

One engine (the 421) has 3 2bbl carbs. The people may not be able to identify the 421, but they can identify multiple carbs. To them, that is "way cool."

I'm not trying to pee in your Wheaties, dude. It is certainly possible to fit the GT engine into an F-250 with a little engineering and make it work. Most of us are just saying that you probably will not be happy with the results.

 

Well Like I said I am still weighting my options, I am still considering not doing the dry-sump system, I may go ahead and just get the Wet sump block like mentioned before, I am probably gonna build it with Manley Pistons, does anyone know what kind of pistons are used in the GT to begin with?

 

I think you should figure things out a little differently. I think you should estimate the weight of the superduty you seek to get into the tens, and then estimate the horsepower, rpm in the traps and gearing needed to accomplish the goal.

Grumpy Jenkins had a small block chevy vega (2000 lbs?)which was 10s or better and he was revving around 10,000 rpm in the traps with axle gearing in the mid 5s.

 

I realize that, But you guys make it seem like its impossible when reality is really isn't, I mean there a guy who put a GT motor into his lightning, and ran a 9.99 a believe.
