According to that article, shelby would be used as an outside upfitter for the suspension, etc. If it was the case, I doubt the shelby name would be involved, but it would allow them to get some extra work.

This is commonly done with other suppliers like ASC and Kar Kraft

Again, i'm very skeptical, especially considering how many engine combinations AAI has to currently handle. However, if it is true, i'll have to look into how I could retrofit those engine parts on my car.

A production 400hp 4.6L isn't really a stretch. The GT's SOHC V-8 is hardly pushed to the limit in it's current 300hp guise. The better use of compression, improved manifold design, and the implementation of better exhaust technology should easily move a well developed, premium fueled version of that same SOHC to 350hp. Frankly, a simple move to higher compression and premium fuel would likely get you to 330hp or so.

When 350hp 4.6L SOHC V-8's are entirely within reach 400hp GT-headed V-8's hardly seem a stretch either. For the sake of argument that comes out to just shy of 87/hp liter by the way.

Will it happen? Who knows, but it would be nice. Perhaps this is an indication that Ford has embraced the concept of 'perfecting' models two to three years after their release much the same way the somewhat gangly 928S became the 928S4? Or the way Ferrari's attractive and fun 348 became the heart-stopping 355?

My above comments made, I too am skeptical that Ford will actually do such a thing even if doing so is entirely within their reach.

Missed one

2001 (Cobra) 4.6L 4V = 320 HP

There is only one way to get more HP, more fuel and air. To get that kind of HP gains they will have to turn a lot more RPMs or shove it in with FI.

Again, not really. The GT's 4.6L SOHC V-8 is, with respect, as run of the mill as they come. And this with SOHC, 30-valve per cylinder heads, a low compression rating, and regular unleaded in the tank. This SOHC motor has a lot more left in it, especially when higher compression and premium fuel are thrown into the mix.

There are plenty of ways to make that much power without FI.

I bet Ford is going to go with 390hp rating on this engine to match the 390cid that the original bullitt had

I'll stand by what I've said. 400HP NA Fed legal from the 4.6? No way.

Now 400 HP from a NA 4v 5.4, that I might believe...

Maybe Ford found an additional use for the GT engine castings. :wink:

PS. The 5.0 Cammer is only around 400HP in "street" trim

The 5.0-liter V8 crate engine is a descendant of the SVT Mustang Cobra 4.6-liter engine family. One big difference is larger 94-mm bores (compared to 90.2) with flanged cylinder liners resulting in the 5.0 liters of displacement. Other differences include forged pistons, an 11.0:1 compression ratio, ported heads, higher lift cams, and beehive-shaped valve springs.
And that's a $15,000 engine

not to put to fine a point on it, however, thats not quite what the article states. ford will be doing the suspension and brake upgrades with packages it has or is currently devolping. the article then goes on to speculate what would happen if ford were to ship unfinished versions for further upgrade to full road racing specs by shelby.
the biggest thing i noticed (well other than all the suspension, brake, engine upgrades) was that the article did state that the time has already been set for the release of the car which - hopefully - means that it is a definate for production and not just a ghost that will dissapear without ever seeing light of day. also, if they know when it will be produced, hopefully that means they already have information on the car itself, thus, the information we are seeing is accurate (to some degree).

The GT engine casting is unlikely to end up in anything built by Ford outside of the GT itself since it wasn't designed to pull duty in your typical, FR vehicle. One small example is that there isn't a place on the block for a starter to mount. I could see a modified, production friendly, and less expensive, version of the same being utlized per chance, but if this were to be the case the GT500 would almost certainly get it first, but unless it was a cheap and easy change-over that looks good financially I wouldn't bet on it with the new Boss engine program coming.

As for you comments regarding the 4.6L and 5.0L Cammer. Frankly, one has very little to do with the other. Heads, intake setup, everything would be completely different which means that there is simply no basis for a comparison here at all...particularly since production was never really a consideration for this engine. I understand why you are saying what you'e saying, but you just can't get there from here.

I find this a bit unlikely, but not because it is implausible.

It would make perfect sense for Shelby to make a GT350 if the upgraded suspension was already in place from Ford.
that is how I read the article, I hope this is finally a decent S/E 197 that the average Joe will get a chance to purchase

The jury is still out regarding whether either of the recent "rumors" are fact or fiction. I can't wait to see what shows up in New York. Personally, I'd prefer the 4.6 DOHC in either a Bullitt or Boss Mustang as opposed to the 5.4L. Primary reason being the lighter weight DOHC alloy 4.6L will allow whichever model the engine might be installed in (it could appear in both the '08 Bullitt and an '09 Boss) to achieve a more balanced weight distribution and thus perform better in the twisties than other Mustangs models. Overall, exciting news if indeed it becomes a reality.

I'll believe it when I see it.

Especially considering that the 4.6 4v was said to be the BOSS 'niche' engine but was canned due to them not being able to get 400hp out of it reliably.

Fourcam on SVT has stated (and this is in the 2010 section) that the BOSS was suppose to have the 6.2L BOSS engine, but will probably come out with a 380hp 5.4 4v, and the 5.8L BOSS engine not making it into the car until at least 2010.

I can't wait to see what the final specs are for the bullitt now. Up until this time I didnt really expect much in the way of performance upgrades over the GT. I hope they come through with something as cool as this sounds.

Fourcam went to his source:

LOL!!! Hah! That's the previous iteration of the "BOSS". XX designed the intake for it. It's basically a 2001 Bullitt style, mirrored, and with larger runners. It also has the Shelby GT500 heads on it. It's a 4.6L, and it only made 332HP with 10:1 compression.
That program got axed over a year ago! They wanted a dual runner intake, which XX also designed for them, but that proved too costly to manufacture, so they killed the program. XX warned them of cost way up front, but they wouldn't listen. XX also made as much power with the single runner manifold, but again, no one was interested.
It's not it guys.... sorry to get your hopes up

as previously stated regarding the Bullitt:

I'd be surprised if it hit 330HP. </TD></TR></TBODY></TABLE>

And the BMW most likely has VVt on both intake and exhaust cams, plus other tech like direct injection. Considering the Boss 290 in Australia makes around 389 horsepower from the 4 valve 5.4, I don't see how they could get 400 from the 4.6 either. That would be rated ten higher flywheel from Ford than the 03-04 Cobra's with the eaton! I think 350 horsepower is more realistic.

That intake looks really restrictive as well, compare that to the tall, equal length, straight shot runners on the 00R and the Boss Falcon motor, no way that thing could make 400 horsepower... And it didn't..

I don't think we'll see a N/A 400 horse engine in the Mustang until the next decade, they are moving slower than molasses..

And like the Audi RS4:
<TABLE cellSpacing=0 cellPadding=0 width="100%" border=0><TBODY><TR><TD class=TechnicalB width="52%">Displacement cu in (cc):<SUP></SUP></TD><TD class=TechnicalB width="48%">254 (4163)</TD></TR><TR><TD class=TechnicalA width="52%">Power bhp (kW) at RPM:</TD><TD class=TechnicalA width="48%">420(323) / 7800</TD></TR><TR><TD class=TechnicalB width="52%">Torque lb-ft (Nm) at RPM:</TD><TD class=TechnicalB width="48%">317(430) / 5500</TD></TR></TBODY></TABLE>

Won't make any near the low end torque we so love with American V8s.

Horsepower 300 @ 5750 rpm
Torque (lb-ft) 320 @ 4500 rpm

It wouldn't be the first time that StangUnleashed (aka Blue Oval News) posted old information as if it were new. They can be a great source of information but you have be mindful of the chaff that sometimes gets in with the grain.
