    The question is whether a Barra I6 would fit inside the S197 engine bay and leave enough room to spare at the front without hitting the fan. It's a long engine and at best it would be very tight.

    The 11+ 3.7 V6 stangs all got a 7.5" rear end. Did the 4.0 V6 in the 05-10 V6 get a 7.5" rear end....or a 8.8" ??? The oem 2 piece DS in the 11+ V6 cars explodes > 115 mph.

    Any perceived eng conversion is gonna end up costing one helluva lot more $$.

    The 05 4.0 I had had a 7.5", and it had a single piece DS. It didn't explode at 115 mph, I speak from multiple experiences LOL

    I'm pretty sure all Mustangs got the 8.8 starting in '11. Now I gotta go look it up.....

    OP has a 2010 4.0L V6.......comes with a 7.5" rear end + 28 spline axles..... that entire mess would have to be replaced..... with a new 8.8" rear end... + 31 spline axles. Done right, the junk oem LSD has to replaced with either a Eaton tru-trac ...... or the HD tru-trac, (which requires 33 spline axles). Then an adjustable PHB + brace... or better yet, a WL watts link. The oem 2 piece steel DS
    should be replaced with a DSS-DS.

    The brakes on the V6 leave a lot to be desired.

    Doesn't matter which way you look at it..... the entire project would not be cost effective..... and still not worth much...2-3 yrs down the rd. It's either a labor of love....or a love of labor.

    I know that. But you also said...

    When they did not. They got 8.8's. Same as the GT's. All I was doing was correcting this small error.

    Oh yes it does, check out the YouTube videos with Barras in the S197. I posted two
    videos on Facebook in one of the mustang groups. They fit, there is a KIT for them.
    I found one of them:


    WHY people like the Barra:

    I forgot about that overboost feature...
    600HP from a stock bottom end.

    If I had the money, I'd do it for the originality. I know there is a bell housing
    adapter for the manual trans, and an ECU wiring kit for the S197s.

    Australia is supposed to get an Ecoboost version for the Mustang there.
    ECO UPGRADE
    The Barra cops a major upgrade courtesy of a cash injection from Ford USA – and led by Aussie engineers.
    Costs are amortised over a global product and the engine could even slot into pick-ups in the Land of the Free.

    F6 IN THE WORKS
    But, aha, Ford is easily able to cook-up even hotter versions for the Aussie, US and all other overseas
    markets. An F6-equivalent variant pumps out a GT350-scaring 370kW and 670Nm. In Oz, we’re talking $65Kstarting price and 0-100km/h in the mid fours. Carbonfibre wheels made in Geelong an option, just an
    expensive one.

    YANKS GO NUTS
    The more affordable Barra-powered Mustang is a huge hit not just in Australia but in the States, the factory
    producing the engine is almost unable to keep up with demand.

    They all got the 8.8" starting in 2011, but they all didn't get the same driveshaft/flange. The
    flange on some of them (later models?) work on the 4.0 V6 8.8" conversion with one piece
    shaft. I was told that... The OE V6 shaft is basically one piece with a slip yoke anyway...

    The GT's two piece fails at the carrier bearing. The V6 doesn't have that issue with its
    basically a one piece shaft. It has a slip-yoke, but it's not as close to the rear yoke as
    it should be. However, the V6 shaft will twist, or blow U-joints under V8 torque eventually.
    The splines may also strip, who knows.
