I have never really cared about 5L, I say a 5.8 minimum is needed in the GT. chevy uses 6.0 or 6.2 and 7.0.

 

Perhaps the 5.0 rumors might involve not a Mod motor varient -- presuming they might be winding that series down as they gear up for the Hurrican/Boss series -- but rather, the Jag AJ 5.0 which will apparently be coming out soon and still has a bit more future left in it. What might give some credence to this is that leaked poll a while back in which they were asking if Mustangers would get their panties in a bunch if they put in a motor from Jaguar. That would not be a bad thing at all IMHO as the AJ motor in Jag form is a really nice, refined performance oriented motor and I think would reflect well some of the small, powerfull, revvy character of the original Boss 302 road/track racer. It would certainly be more interesting and unique than yet another Mod motor sprinkled with bits from the FFRP catalog, again. A nice, healthy 375-400 hp out ought to be readily doable (heck, Audi's pumping out 420 hp out of a 4.2 and Bimmer's doing the same from just 4 liters).

Would have an interesting historical antecedant when the British Rolls Royce Merlin engine was popped into the then fairly mundane North American P-51 Mustang creating the legendary C and especially D versions.

Then Ford would have the bigger, simpler OHV (supposedly) fresh out of the paddock Hurricane motor for, say, a Mach I, for which a big, torquey motor would fit that model's drag/stoplight racer character to a T. Speculation seems to have that pumping out around 425 Clydesdales.

I would imagine that the base Stang GT would soldier on with the old war horse 4.6 slightly freshened up with perhaps 320-340 ponies or so.

 

Everyone in the know is saying that the AJ V8 isn't a consideration. the Jag mill is too expensive and offers no advantage compared to the less expensive route of updating the Mod motor DOHC's or otherwise.

 

Yeah I think its probably based off of the Mod or Hurricane platforms.
One of the 2....probably the former

as per BlueII on BON:

 

If its 5L DOHC TT it'll do quite well against the bowtie's cubes, and get better mileage while doing it.

 

I concur if it is TT then i would be happy with 5L

 

Perhaps, or even probably. But if -- going way out on speculative limb here -- Ford is going to be dailing down the Mod motor family to make room for the Hurricane motors, then perhaps reviving the 4V cylinder heads on a new 5.0 block (or some combination of new block, crank, rods and/or pistons), that itself would seem like a lot of time, trouble and money heaped onto a fading motor family. A lot of trouble particularly if this is going to be a very limited run, single model run. Isn't excessive cost the very reason they haven't done a production Mod motor 5.0 already?

Option 2 would be simply to dust off the 4.6 DOHC 4V motor, give it a proper tuning towards the 400hp mark and plop it in a Boss Mustang or something. While certainly easier than developing a 5.0 mod motor, it would still be heaping money on a limited production, one-model motor rather than the new Hurrican engine line.

Option 3, aforementioned Jag motor, may not be as unreasonable given the above and some other consirations:

• Ford's obviously been toying with the idea, at least at a conceptual level, as revealed by that poll a few months ago.
• Jag will be making a 5.0 version of the AJ motor anyway, which could then simply be shipped over and dropped in the Stang. No significant new development or production tooling as would be the case with a 5.0 Mod motor. Just pack them into shipping crates and send to Flatrock, Mich.
• The AJ engine family looks like it will be in the Jag future for some time yet, so sharing this motor with Ford US to plunk into some quasi-premium specialty models makes some financial sense (economies of scale, defrayed development costs, etc.).

Again, I'm out here with the sparrows on a limb of speculation, but it's not wholly illogical nor inconceivable.

Probably the most likely is that we're not going to see any 5.0, whether Mod or AJ motor. The 3.7 V6 will put the old 4.0 out to pasture in the base Stang. The 4.6 will serve out it's tour of duty in the GT as long as that production line is still churning them out while up market Stang models might get the Hurricane in 5.8 (Boss 351?) and 6.2 (Mach I) sizes or even a rumored 7.0 (Shelby 427?).

Size and power spreads would make some sense: 3.7 @ 275hp, 4.6 @ 325hp, 5.8 @ 375hp, 6.2 @ 425 hp and 7.0 @ 500hp.

 

Well if the 3.5 TwinForce can pump out 400hp

500+HP for a TT 5.0 is EASILY obtainable

Me rikey

Even funnier.
Back in the day when the 2005 was originally suppose to be a 2003.5
the GT was suppose to have a 4.6 and a 4.9, and the cobra was suppose to be a 5L
Also..after THAT changed. a SOHC 5.0 was suppose to go into the GT
and a DOHC in the Cobra

How times change yet remain the same

 

The already have a 5.0 motor thats been tested in certified. It currently resides in the saleen pj and fits the bill nicely. Boss 329 has a nice ring to it (wink)

 

Didn't think the 5.0 Motor in the Saleen fits the bill.
IIRC its a 4.6 that's bumped to 5.0
And probably wouldn't pass Fords engine tolerances and emissions.

The NEW 5.0 seems to be based on the mods, but purpose built to handle a LOT
and have newer technology in it.

 

AJ isn't unthinkable but as you indicate it is extremely unlikely. As a short term solution I think a tweaked version of the Mod motor has it covered fiscally and as a long term solution I think it likely that Hurricane looks better. Apparently Ford has considered 5.0L versions of all three. As far as I know AJ is the only one that has supposedly been shelved altogether.

 

Boomer I know. I mean if they wanted to do a quick boss rendition. They just messed with the stroke did some porting etc.

 

Oh..gotcha..

And an update as per Blue II

 

Sounds right since the new f150 will have twin force for sure. F150 has always been a good indicator of things to come.

Agreed. A DOHC 5.0L powered Boss 302 would be an awesome ride.

I do think Ford has most of the right pieces in house to launch a 5.0L DOHC Modular powered Mustang. FRPP already has existing all alloy block and heads ready to go now - the largest missing component is an emission legal intake which can be developed for little coin and minimal time. Developing such a beast would be the perfect send off the modular engine family before the H/Boss engines take center stage.

 

I doubt you'll see a 5.0 short deck mod motor variant, as has been pointed out here and other places, the 4.6 doesn't have enough meat between cylinders or at the bottom of the bores for long term durability. A 5.4 would be a better option (and just to pull the wool over everybody's eyes they could say it was built using the OZ Boss components - that way people would gloss over the fact that Ford doesn't produce an aluminum 5.4 block and just bask in the aussie goodness beating uunder the hood). A 3v 5.4 (lightest configuration for the 5.4) can produce 375 hp no problem in a premium fuel tune and probably upwards of 400hp with a little factory hot rodding and in a configuration like the GT mustang would probably weigh in at or be lighter than the next gen Camaro.

probably means GM 6.2 (LS3)

 

Sweet. I wondered if they might get to 5.0L on a Mod Motor block by using a bit more stroke, or a combination of a bit more stroke and a bit more bore, in what is essentially a 4.6L block.

 

I can't see them using the Jag motor. I'd bet hard cash against that.

The other thing is, with gas/oil and energy getting more $ by almost the day, I really can't see too much more of this one-upsmanship on the CIDs going on too much longer. One thing Ford has that the others don't is a nicely developed small V-8 program. GM can't get anything less than 5.7 liters doing much. I think they will continue to try and get more from less.

Even if we do see a "big block" something, it'll be more money than most of us can afford.

 

Were do I sign up for a TT V8 Mustang?
