No bubble bursting at all, we are each entitled to our own opinions and views. It's all good!!

You and me both!! The Cammer would be my first choice, hands down. If Ford could satisfy that dream, I would hope they can provide such a Boss in sufficient quantities to make it affordable. Sadly, I doubt Ford will ever provide a Cammer under the hood of any production vehicle.

 

I'm willing to bet that you have never driven a cammer equiped car or a 2000 Cobra R...so I'm not sure what you are crying about when all you are looking at is a spec sheet.

 

First of all Chris, why the personal attack? I'm not just looking at a spec sheet, the Cammer is a great engine. And since you brought it up, I have in fact driven a Cammer equipped FR500C. Unfortunately, it wasn't mine.

 

wasn't a personal attack, but you are so set on cammer that you aren't even talking the into consideration the facts of the 5.4.

 

The 5.4L is a fine engine, just too heavy in iron block form for a Boss. The Boss has offer stellar handling and braking performance with a curb wegith much less than a GT500. A heavy iron block engine, regardless of displacement, doesn't fit in a Boss Mustang. Certainly an aluminum alloy 5.4L could be an option but the cost for such a block far exceeds what Ford is willing to invest for a single model.

 

the 2000 R had an aluminum 5.4 i know it was a $55,000 car but its not like ford hasn't done it before.

 

I read the link provided at the beginning of this thread and I didn't see where anyone said it was definitely going to be an iron block. If I missed it please show me where it said that.

 

The cammer will never be put into a production Mustang due to it's thin cylinder walls. So that's out, it's between the 4.6, the 5.4, and the 5.8

I'm not a fan of the heavy cast iron 5.4 either, if they are goingf to go with the 5.4, it has to be with the aluminum block or it won't be very impressive. Imagine a GT500 with it's blower removed, it would be a slow heavy pig.

 

The 2000 Cobra R had a cast iron block with forged steel crank. The full description of the R is provided in the link below. Although it was stickered for $55K, they generally sold for much more - those lovely dealer ADM's again...

"The basis for the Cobra R’s engine is Ford’s Triton 5.4-liter cast-iron modular block and forged-steel crankshaft. While the cylinder bore is the same as the 4.6-liter aluminum-block engine, this block’s deck height is 29mm taller. The stroke is 15.8mm longer (105.8mm vs. 90.0mm for the 4.6-liter), which provides the added displacement."

Outside of the uber expensive all aluminum 5.4L in the Ford GT, I don't believe Ford has offered the 5.4L engine in anything other than a cast iron configuration. Certainly, they aren't going to use the GT engine block in anything but a supercar like the GT for cost and exclusivity reasons.

It doesn't state that specifically in the thread but Fourcams posts implied that Ford intends was to use the GT500 engine sans the blower for the Boss.

EDIT: Sorry for the double post

 

I am mistaken, some reason i had thought the 2000 R had an aluminum block.

 

Doesn't the entire blower set-up (super-charger, inter-cooler, supporting hardware, etc) add 150 to 200 pounds to the car, The Shelby that is?

 

I not 100% positive but I think that this a reasonably accurate estimation of the weight penalty imposed by the blower (if anyone knows for sure, please correct me). Even if we assume it's 200 lbs on the Shelby, taking 200 lbs out of a 3,900 + lb car yields a 3,700 Boss with the 5.4L - still far too heavy to be a Boss Mustang.

 

Well... that's just engine

If it doesn't have the 6 speed it'll be a bit lighter.
And who knows what else they have up their sleeve.

 

Just out of curiousity, how much weight difference is there between the GTs aluminum 4.6L 3V and the iron block 5.4L 4V?

 

Not sure, but alum vs iron, 2cams vs 4 cams, 8 extra valves, more material in the heads, etc...

 

Gotta be close to 150 pounds..

 

I thought i read someone that the 4.6 iron and aluminum were around 90lbs different.. i don't think its as high as 150lbs but should be around 100lbs.

 

I believe the iron 4.6 block is ~70 lb. heavier than the aluminum 4.6.

That would mean the iron block 5.4 is ~90 lb. heavier than an AL block would be.

One thing you guys are forgetting is how much heavier the 4V heads are than the 3V heads. Each 4V head (fully assembled with cams & valves) weighs ~30 lb more than a 3V head. That's right 60 lb extra in heads for a 4V engine over a 3V.

So a 5.4 with iron block & 4V heads would weigh >160 lbs more than the 4.6 AL block, 3V. Some of the extra lbs come from longer rods, crank, longer chains, larger intake mainfold, etc. It all adds up.

 

Excellent point on the weight differences between the 3V and 4V heads, I completely forgot about that.
