That long hood deck looks way out of scale to me. I wonder if it has a false nose on that test mule. It going to be a loooooong winter assuming we will start to see some real cars in the Spring.

They're also speculating that the 5.8 will remain. First time I've heard this.

I was wondering if Ford would continue the 5.8 Trinity engine as I'm sure I cost a bunch of money to develop it for only a 2 year run. So it makes sense to keep using it for the new model.

Yes this sounds great to me especially if it's true they drop the 400lbs off the new Mustang it'll be one hell of a performer.

Interesting, but I'm not sure I buy it. The 4.6/5.4/5.8 architecture is getting pretty old. The future is variable cam timing and direct injection. The older architecture allows for neither.

 

But hey who knows.. Long live the Trinity!

weird they are now claiming Ford continue on with the Shelby name. when I toured the Shelby factory in LV, they said they were done with the direct partnership with SVT and would only do post production conversions for individual buyers.

It will NOT be a 5.8. It's fact that that engine will not fit the new chassis OR make upcoming EPA regs. Plus. Look at the new Eco boost race engine roush is playing with..... Makes sense to me the new car is going to be an EB 5.0 called a GT350

 

I saw some shots of a camo 14 500 with IRS bits and funny exhaust routing..... Figure if you are going to test it why not on the big power...

I thought Ford purchased the naming rights for the GT350 and GT500 from Shelby well into the late 2010's? It seems like it's almost a lock for a GT350 in 2015.

Shelby Licensing still has the GT500, GT350, Shelby rights, but like the Shelby GT500 program, all it takes is a fee per vehicle to sick the name on. The new 2016 chassis and body style will not have room for the 5.8. I also doubt that there will be an Eco Boost V8 as the current turbo power toys are transverse mounted (sideways) and that would not fit in the new design.

 

I expect any power adder option to the V8 models will require hood modifications that could be done through after market mod factories like SA.

Exactly right. Turbo V8 packaging is extremely difficult and made even worse by todays EPA "quick light" cat requirements. I don't see it happening.

 

Again, exactly right. The new hood angle will probably not allow for a top mounted SC option without hood modifications. I've read that they plan to sell the new car in europe which has strict pedestrian impact regulations. I say just teach your drivers to stop running over people and leave the hood angle alone, but that's just me....

The 5.8 is substantially the same engine as the 5.4. Not sure whether they changed the bore or increased the stroke, but its not a new iteration. Therefore, not such a big hit to lose the engine and try one that will fit and provide the necessary horsepower.

If I'm not mistaken it's also the same size block and heads I had on my 04 Cobra and the same as the first twin cammed late 90's N/A 4.6 Cobra's also.

The 5.8 block is basically a 5.4 block with the bore liners removed and a spray in bore liner installed. It's a high tech process and is very thin but wears like a normal liner. Saves weight and gives the bore increase. Neat stuff. Very expensive though

The 5.4/5.8 is a tall deck version of the original 4.6 from the mustangs and crown vics of the 90's. The taller deck height allows for increased rod length/stroke which provides the additional displacement from 4.6 to 5.4. The additional displacement from 5.4 to 5.8 is due to the plasma arc spray bore technology that allows for a much thinner cylinder liner than the traditional iron liners typically used. This allowed Ford to run a slightly larger bore diameter resulting in the additional .4l of displacement.

 

Ignoring slight variations between the years, 4.6 and 5.4 engines can "share" heads between blocks to a certain extent. For instance, the 3 valve head on a 2008 Mustang GT was pretty much exactly the same as the 2008 3 valve head on the 5.4 F150 motor. The same thing applies to the 2 valve heads of the early 2000's. Keep in mind, there are differences in Cams and/or Cam timing with these different head applications.

 

The 4 valve cobra/Navigator/GT500 heads are a different animal. There have been several variations over the years of these performance orientated heads culminating with the GT500 heads we enjoy today. I'm sure there are several great write ups online that document the development of these 4 valve heads.

Awesome information. You need to post more often :thumbsup:

What I was told from a source close to the S550 project is that the next GT500 won't hit until 17 or 18. It engine won't be anything bigger than the current 5.0 because of size restrictions in the new engine bay. The GT350 will be a better handler than the current GT500 and LS Boss 302 but the 13-14 GT500's straight-line performance will not be topped for a few years.

If you say so....

Lol

Laugh all you want, time will tell. With attitudes like this no wonder this forum is slow. Edited by bpmurr
