Ford did this in the 1999 Boss Mustang concept. It looks like it was a 40 valve motor though, instead of the 20 valve V-10 you have. IIRC the motor mounts are in the same location, so it's more a matter of some fabricating and tuning. It would certainly be unique, but for the amount of money and time it will cost to do this you could build a forged motor with a torktech supercharger kit and have a much more fun to drive stang.

anything is possible as long as u got $$$ but also take into consideration do u have the ECU? do u plan on modding it if so what mods are actually availiable for that motor and then what more modification do u need to do just to make those mods work and fit is it really worth it ditch the motor and start a rebuild with internals and all
+1, keep in mind if you wanted it to be a high performance application you would likely want/need custom cams (not sure if the stockers could be reground, because I don't think anyone makes aftermarket 6.8 V-10 cams), custom headers, a sheet metal intake, ported heads (they'll flow the same from the factory as the existing PI heads unless you have 3V heads but you didn't specify), would you be adding forced induction? if so, perhaps rebuilding with forged internals; if not, rebuilding with different pistons to raise the c/r, etc...
I think it would make a great project and would be a very unique car for sure. I am in no way trying to be negative, just trying to give you an idea of things to think about before executing your plan.

I wouldn't want the 6.8 in a Mustang. It's not a performance engine by any stretch of imagination.
The V10 in the Mustang Monthly article was a one-off based on a 4.6 block. The 6.8 is based off the 5.4 block, so it will be quite a bit wider than the 4.6, and has a bore-stroke ratio that is hardly ideal for performance.

I like the part about "it's all the same just 2 extra cylinders". Unfortunately, I think it'll be atleast at tad bit harder than that. The fuel system, drivetrain and everything will have to be removed but I'm not sure what all has to be replaced. I would like to someone here complete the project. That would be rare
The Boss 351 is the name of that Frankenstang that they did that article on years ago. They built the entire thing using the SVT Department's corporate credit card and kept it under the corporate radar. Yes, John Coletti could get away with that kind of stuff.
It was no conventional V10 though. They basically took a 4.6 and grafted an extra set of cylinders between 2-3 and 6-7. They got real crazy with the crank using three 90 degree offset rods and alternated with two 60 degree offset rods on each cylinder bank rather than using 72 degrees on each one. I don't know that they mentioned the firing order but they said it sounded nothing like a Viper or a Italian V-10.
The heads were tumble port C-type heads and used the same grafting concept as the block. They sourced a set of custom cams based on a Volvo 5 cylinder design and ran a graft design intake manifold.
It all ran through a built T-56 based on the cobra R and connected to a Ford 9" rear end.
They ended up using a pair of modified Volvo ecm's and ran each cylinder bank as an independent engine.
Despite all this duct tape engineering, the engine ran awesome....the only problem was they didn't have a clutch that could hold all that power. It vaped two clutches during the article writeup.
IIRC, they were able to get right at 600 ponies to the wheels. I had dreamed they might put that engine into a special edition mustang. Sadly it never came to be.

"...the V-10 version has gone as quickly as 11.93 seconds at 117 mph on Ford's Dearborn Proving Grounds."
Not worth it as a performance addition as the 2011 5.0 Auto Mustang is running about there with full bolt ons, but if you had one laying around and your 4.6 **** the bed I would say go for it.

There is absolutely no reason for it. My 2V hit 643RWHP at 6000rpms and it's cammed for 6500 with an old S-Trim and livernois heads. If that's not enough horsepower, I'm guessing it will come close to 700 when tuned. The problem with the mustang is it's already nose heavy. I got an aluminum block to get weight off. Unless you are simply drag racing and you need the weight in front to keep the front end down, the GT has plenty of horsepower in it.

I'll say this: That V10 mule sounds infinitely better than any Viper V10 I've ever heard. That mule just sounds bad (in a good way

well really there is no reason for a 600+ horse power Mustang...sometimes we do thing because there is no reason for it
if I had a Mustang with a dead 4.6 and a brand new V-10, I'd look real seriously and dropping the V-10 in just for the heck of it...sure it probably will never be fastest Mustang around but it would be among the most unique around
