On the flip side, I hear that the LSA going into the F5 will use the same cast pistons used by the CTS-V for NVH reasons (forged crank, forged rods, and cast pistons - jeez, talk about hamstringing. The LSA is also said to be fairly close to its max safe output in stock trim- much higher and the bottom end needs a switch to forged pistons)

This, 555/555 will have the goods, but Ford really has to work on that rear suspension (not talking IRS here), the axle hop is silly with the current 3 link and despite being IRS equipped the F5 does a better job of getting the power to the ground on launch.

Piston material will make a difference in NVH? Who woulda thunk it...

Now Autoblog has it too, no direct mention of the Road Runner name though:

New update: "Road Runner" is a naturally aspirated 5.0L V8 with a slight bump more horsepower and higher RPMs than the Mustang GT "Coyote" 5.0L V8. I'm betting it's your 2012 Boss 302 engine.
just how it should be!!!!!!!!!

If it's not a nice round 450bhp, I'll settle for 429bhp in the new Boss 429
Interesting that Autoblog then question the TT Coyote themselves, pointing out to a "source" that points them to an article that has good solid information. That article is this:
http://www.autoguide.com/auto-news/2...-400hp-v8.html
And that article is referring to the "Insider" right here.
So, if you want to know what's what in Mustangland, looks no further than TMS

Probably around 425, 4cam over on SVT mentioned a 425 hp 5.0L before his access to Ford info stopped and the BON insiders had thrown around 425 as the possible base 5.0L number before it firmed up at 400.

My guess is that the 5.4 will continue on in the current S197 chassis but with a swap to a lighter AL block and minor tweaks. Then, in 2014/5/whatever, with the advent of a new platform, the V8s will consolidate to the 5.0 motor, N.A. in the GT and TT in the GT500. By then, Ford should have had enough time to develop both the DI and TT.
The DI in the GT motor will allow a requisite boost in power, economy and cleanliness to launch the NextStang and will allow for a proper, Ecoboost TT for the GT500. I would guess power levels would not be hugely greater -- figure a +25 boost for the GT to 425 and the GT500 hoovering around the 550hp mark -- but with the significantly lower thirst and emissions that will become much more necessary in the next few years. Added benefit is that Ford would not have two separate engine lines -- the new 5.0 and an old Mod 5.4 -- to keep going, which ought to be cheaper for all in the long run.
Power mavens need not despair because the DI and TT will likely result in much fatter power bands and the NextStang will likely be a couple hundred pounds lighter and sleeker, all of which will bolster performance.

From the BON insiders:
B2 - 6.2 TT & 5.0 TT (no DI) are real. Nothing in stone though. Short memories are real though.
TOW - DI (either NA or boosted) was canceled on all V8 gasoline engines about 2 or 3 years ago. Rumor is "not cost effective" compared to non-DI.

I think the 5.4 will be gone from the GT500 after next year. There is no way they will keep it around just for a few thousand GT500s after it is gone from the F150. They probably just have a bunch of Ford Racing aluminum blocks sitting around that they figure they can get rid of in next years GT500s, and then be done with it.
I think the most likely replacement will be a SC'd 5.0 and not a TT. Ford has the the SCed V8 down to a fine science. They know how to get the kind of power they want AND make them rock solid dependable as well. I can't see them switching to something they aren't nearly as experienced with when there is the Z28 looming. They will go with what they know.

I'm also amused by the "Coyote can't catch the Roadrunner" implication with the names.

I don't see that at all. Ford will probably treat the AL-block GT500 as an entirely new engine program -- that is, new designs on some major components and the accompanying validation testing that goes into any new engine program. IMO, this engine will be around for a lot longer than one year.

The 5.4 is also being dropped in Australia, so even on a global level the GT500 would be the only vehicle left using it? And from what we have heard, the 5.0 can make equivalent power to the 5.4 while being lighter and more efficient anyway.
Everything points to the 5.4 being gone after next year.

Since the GT500 is such a low volume seller, all they have to do is manufacture enough parts for 3-5 years (enough for say 10,000 cars) before they cancel 4.6/5.4 production. Then just assemble the engines as needed. That would possibly help keep cost down for the AL block.
On the topic of Z28, does anyone know if ford is planning on upgrading the supercharger, to maybe the ford GT model, or a twin screw in general? (current is roots style still right?)
