Nothing can touch the sound of a V8 but maybe a V10… With that said I wanted to start a new thread that I have not seen much technical information on. I have seen where some have performed the swap on a 1999 and 2005 mustang but they spared no expense… I would like to do this cheap and document the steps for others. What got me started: The sound of my Mustang is awesome but I compare to the many Harleys I have owned, a lot of show but not much go when comparing to the crotch rockets. I initially looked at modding my 4.6L but came to realize that to get real good power “which I know is subjective” real good power to me is 350 horses and 400+lbs of torque. So my research on the web led me to a 5.4L 2V or 3V, but then I saw some brief threads on the 6.8L so now I’m considering a 2005 6.8L V10 SOHC swap. It may be a bad idea but let’s explore it… Hey a V10 Mustang would be Bad Ass and my Blue Convertible with Cobra wheels and Stalker Body get will be able to back its show with go… Oh and the stock power from a 2005 6.8L V10 is: 362 hp and 457 lb·ft Max Torque: 3250 rpm and Max Horsepower: 4750 rpm What I have learned from the Web: The Modular engines from 4.6 to 6.8 all have the same engine mounts. The 4.6 is approximately 24 inches long and the 6.8L is 27 ½ inches long. Height from Throttle body to bottom of oil pan for the 4.6 is ~ 27 1/8 inches high and the 6.8L is 28 1/2 inches tall. In contrast the 5.4L 3v from the Navigator is 35 ½ inches tall but the 5.4L from with a Sullivan intake is 28 ½ inches tall. The 5.4L from a E350 van may also work. The 4.6L weighs ~ 500lbs and the 6.8L weighs ~ 640lbs Things that I think I know… Found a new 6.8L for $2,500 with everything. Headers on eBay are $150.00 for the 6.8L “Not sure if the would fit but good starting point.” Installing a tubular cross members which would help compensate 50 to 60lbs for the increased weight from the 6.8L and may allow for pushing the engine back towards the firewall about and inch or so… $350 - $1,000 Move the battery to the Trunk move about 30lbs to the trunk My hood is a stalker hood which should be lighter than the stock and provide for more clearance Stronger clutch “recommendations” Drive Shaft? My concerns that I need clarification for: Would the Mustangs 5 speed manual gearbox connect to the 6.8L block? Would the ECU from the pulled 6.8L work in place of the Mustangs ECU or should I consider a standalone system? My guess gearing changes would need to be made Please critique my idea it is in its infancy and please be a devils advocate so I don’t make a mistake and by all means correct my terminology as I’m not a mechanic.

DOOOOOOOOOOOD. Awesome. I don't know if you're near Savannah, Ga but If you are i'd like to volunteer my time as much as possible. I have thought about this for a very long time. I've had every type of motor you can think of, diesel, V8 and V10 (cause they don't make anything smaller than a V8 if I recall lol). The reason the V10 makes power so low is the cams, you'll probably have to have custom grinds, but it would be worth it. The exhaust is doable. Just need to do a little fab work. Custom intake would be necessary as the stock V10 intake also dictates where the V10 makes power. I think you have a great idea, I also think it will cost A TON OF MONEY. Definitely not the cheap route, but definitely the cool route. Ignore the ones saying not possible and the extra weight will kill the power blah blah blah.

Just a thought here: have you ever wondered why motorhome manufacturers stopped using the powerstroke diesel engines and mainly use the ford 6.8 V10 in motorhomes now? The V10 is the same as all of the other mod motors and is ultra reliable. It will cost a lot of money but if you're willing to invest the time and the money to do it I think you will have one hell of a monster on your hands. Anyone can bolt on a turbo or a s/c, it takes one hell of a person to try what everyone else says can't be done.

It can be done, hope you try it. Holler if you're close to Ga.

Thread is 2.5 years old now...

Holy Balls... I think there might be light at the end of this tunnel. Dad just got a job in South Carolina (but he's in Texas, WTF?) so his RV bay garage with a commercial grade 10 ton lift is now AVAILABLE... Not to mention he befriended a Canadian immigrant who should have been born in America because he loves guns and FORDS just as much as any real man from here. Looks like I might be able to post some photos of me actually making progress soon.

Oh, and I know the thread's old but believe me, it's not as old as it FEELS. Every time I walk by my mustang in the driveway I ask myself, "why, oh why, didn't I just replace it with another 4.6?" Fortunately I'm not kicking myself in the ass as much as I used to. I just can't wait till it's actually done.

[WickedSnake00]

Awesome. Glad to see this thread didn't just die.

[Willy Mo]

no kidding, i hope to hear of some pregress soon.

Let me get this straight... You're going to spend well over $10,000 putting a 6.8L V10 engine in your mustang, but you're worried about having to fill it with premium....

[breidhaupt]

everyone was dogging this guy for wanting to pull the swap when he was ust aking for advice to get it done. if i had the money i would do it in a heartbeat then put a supercharger on it

[JerseyTrueBlue]

Not so much "dogging" just giving advice. It may be stern advice but how else do you talk someone out of wasting money. Simple fact is that no one does this swap, know why? There are no advantages to be had that can't be had with something more simple, lighter and less costly. Just saying.

[JerseyTrueBlue]

If you dare to be different and do the swap go for it but don't bother asking the millions who think you are wasting your time/money how to do it.

3v v10 would be interesting esp if its given compression and ported heads
