Has anyone heard about the possibility of a naturally aspirated 5.4L in a Mustang in the near future?

someone was talking of a new bullitt that would have a 5.4 in it.

i hope they put a n/a dohc engine in something, i think that would be pretty cool. but whatever, i hate talking in hypothetics. ad wishes. I am getting my 07gt and thats what i care about

 

Thanks Cheese. When is your car due?

Well I don't think Jack Roush would be intrested in developing 4.6 supercharged Mach 1 for Ford to sell for $35,000. There has to be something in it for him like a 5.4 3v which he could supercharge

 

hey there, my car is due 7/23/2006

anywho, i would think ford would be very smart to put something in between the gt and cobra. But i will allow them to decide what it is.

 

Please explain this to me.....

Most people in here think that the Shelby is a "pig" and "nose heavy" because of the big 5.4L 'SUPERCHARGED' V8. Wouldn't putting a 5.4L in a non-supercharged type of Mustang make it feel more "piggish" then the Shelby? Yes you would be gaining more HP but also more weight. So in the end you would just have a "special" Mustang GT that is heavier then the GT and probably handles worse then the GT due to extra weight up front. I know many would say just to put the aluminum block in the 5.4L just like the Ford GT. However, If Ford exchanged the Iron for aluminum they would have to increase the price as well, and probably adjust it WAYYYY higher. Even if Ford charged 35,000 for it (which would probably never be that low due to that expensive engine) you would still be only a couple thousand bucks for 100 more HP and a warranty on that extra HP as well.

In conclusion, the only way Ford could offer an affordable and reliable product that people would buy is a Supercharged 4.6L V8. However, many would choose that over the Shelby considering that it would be a decrease in weight. Sooooo that only gives Ford the opportunity to grab a roll of vinyl stickers and other misc. parts to glue on (Example GT/CS) and call it a day.

-On a slight different thought... How about taking the new 3.5L engine and turbocharging that! haha.... Your lineup would consist of a "modest" 4.0L V6 then to your "aggressive" 4.6L V8 and then to a "screaming" turbocharged 3.5L V6 then to the "HOLY SH*T" Shelby supercharged 5.4L V8?


But then again I imagine hell would probably have to freeze over before Mustang enthusiasts would support the idea of a V6 being over the amount of power of their almighty V8 Monster.

 

I like the turbo-6 idea, but not a Mustang. Use the platform, and make it AWD. Call it a Cougar for all I care. It'd be neat as hell, and make a great daily driver for winter

 

They call it a pig not purely because of the 5.4. Its because the block is made of iron instead of aluminum. And has the supercharger on top. I think it ends up being like 400 pounds more than the aluminum gt engine. If they built a 5.4 n/a i would bet it would be an aluminum engine.

 

I think, and hope, Ford could build a 400HP Mustang of the same weight as a Mustang GT for $30,000 base price. They are already building 4.6L block in aluminum, why not the 5.4L for not much more? Take the GT block, and due some cost cutting since the engine won't be supercharged. The biggest problem is quantity. Between the Mustang and the Explorer, the 4.6L block quantities are huge (100,000+ per year likely). The 5.4L aluminum block would likely only be used in a special edition Mustang, so the quantities would be very low compared to the 4.6L block. (10-20,000 per year)

With that said I still think they build a 400HP 5.4L aluminum block Mustang for $30,000, optioned like a Mustang GT premium.

 

I remember back in '68, '69 when MG took the 2912cc six-banger from the Austin Healey 3000 and put it into the MGB and came up with the MGC. Fast? Heck, yeah. But if you'd ever driven a MGB, you noticed the difference in the handling IMMEDIATELY.

They made MGC's for 5 months. Nov 68 thru Mar 69 and then they were done. I still like to see 'em. I love the accelleration of the six, but as a daily driver, how did you put it?

Oh, yes. IT WAS A PIG!

Sometimes in the big, bad world, less is more. And 400 pounds up front is NOT something I could deal with.

Don't get me wrong. The Shelby is the best Mustang to date. But there is room for improvement. (See Corvette with its 400hp, 28mpg highway offering).

 

It'll never happen. It would make too much sense.


I would LOVE an n/a 5.4L Mustang... and call it the Boss 329.

 

Forget the 5.4L. What about the new 6.2L????

 

CAMMER!!! work on getting the 5.0 Cammer to be emissions friendly... that already is capable of 500 N/A horsepower.

 

That'd be sweet. Aluminum block 6.2L used in trucks and Mustangs!

 

I'm with you there, it doesn't need to be superblock to handle n/a pressures.

 

It would probably be a $50,000+ mustang with that motor. It suffers from 'LS' syndrome, not enough for way too much.

 

If Ford doesn't have a 5.4 in the cards, it darn well oughta. And an AL block 5.4, which ought not to be a stretch either, ought not to turn it into a dynamic pig either. I thought Ford was moving to have all Mod motors use AL blocks anyway. And evolving the Mod 4.6 block from FE to AL didn't seem to drive its price into the stratosphere. Aside from a higher deck height, the Mod short and tall blocks are pretty equivalent in terms of overall architecture and thus, the switch to AL would presumably be about the same, price wise.

I think a na AL-block 5.4 might have several advantages over a supercharged 4.6 such as less cost, greater simplicity (and thus reliability and mod-ability), and equivalent or less overall weight (and lower CG). If Ford really wanted to get fancy, they could do a Cobra Jet (3V) and Super Cobra Jet (4V) versions, but that would be doubtful. Probably to compete with the bigger LS2 (6 l.) and SRT Hemi (6.2 l.) motors in the upcoming Camaro and Challenger, the 4V version might be the one to go with. Such a motor would be a natural for both a strip-oriented Mach I and Bullitt model. And slap the same heads on the 4.6 block for a track oriented Boss or GT 350 model.
