Hello, my name is Corbin and I will hopefully soon begin a build of a Cobra, and I have this crazy idea about modifying a 3 valve 6.8 (414 for you old people ) Triton V10 and dropping it in. After doing a bit of searching, I have surmised that it isn't much heavier if at all than an iron block 427FE, and after looking through some youtube videos it seems that this V10 manages to make a pretty badass sound
My concerns are that even with work done (valvetrain, porting, lighter rotating assembly, etc.) it won't flow enough or rev enough to be an inspiring motor, which would be rather disappointing. I have done quite a bit of searching, and I can't seem to find anyone who has done this swap, am I missing some obvious flaw in the plan?
Any advice would be appreciated, and I also have no idea what transmission would bolt up to the V10, but there must be one...
Emerson Motor sports built one a few years ago with a Triton V-10 for some guy. He had to do a lot of fabrication work to get everything to fit under the hood. Contact him and see what he says and if you think the work is worth the gain. I do remember the very small valves in that thing.

If you are looking for something different than can make a fair bit of power (be inspiring), looks good and has options and parts available, try a Toyota V-8. There are some hot ones in Australia and a few in the UK. There are some go-fast goodies sold here in the US to make plenty of power.
try this link to see a shot of one from a Lexus, believe its a 4.0

Reason: added link
Thank you everyone for your replies! I never knew there could be such a helpful forum on the internet...

How about a Viper motor........it would look great and give plenty of performance.
Call me picky but I read in another thread that the viper engine "sounds like a triumph humping a volkswagen" and from what i've seen this is true. It also seems to be pretty expensive, though after mods a triton also might be...

If this is true I'll be quite put off, but I read on one of the factory five faq type pages that their kit was designed to fit the V10. Thanks for the lead, I'll definitely call Emerson.

That's quite an interesting idea, but I would be worried about low end grunt, and it would make more sense to use a 5.4 in my mind, but I sure would like to use that 4.0 V8 in a Caterham type of thing, it would be insane!

Isn't the V 10 the same configuration as the 4.6 and the 5.4?
The V10 is the 5.4 with two extra cylinders cast on the end, 362 hp and 457 lb-ft stock for the 3 valve.
It's a truck motor as noted above. Not made for high RPM. It's a perfect motor if you have a 4X4 quad cab and want to pull a trailer. Lots of low end torque but in a stock configuration I don't think it will even spin over 5000 RPM. My brother pulls a trailer with his and can hold the speed limit up the hills as he's passing motorhomes.

Remember, It's never too early to start beefing up your obituary.
My concerns would be parts and maintenance in the future.
Ford is dropping the V10 from production, don't know how long it was produced, but not long, or in much quantity in the grand scheme of things.
Lot of work, special parts, no future. I imagine everyone will ask "what is it", even today. Personally, I don't think it's a good looking engine. I'd go FE or SBF.
And what's the point of mountains of torque in a 2,000 pound Cobra? Are you going to be towing a 28' enclosed trailer behind it with the F-150 inside?
I read on wikipedia that this has to do with firing order, and that the split pin crank design of the ford v10 means it sounds pretty good, though i also read that split pins make for a weaker crank
Edit: According to FFR, all V10s came with a forged crank, so perhaps it's not so bad...

What's the real objective?
Perhaps you can ask yourself and truly answer here first what it is that you are really hoping to accomplish or learn from installing a Triton V10 vs. other power plants:
- Just to do something different?
- A different look or size?
- Different sound?
- Power? (There are other options)
- Extra Torque? (not really needed)
I saw a Cobra with a Ferrari V12 in it about 13 years ago. It looked cool, sounded cool, was an interesting project to see in person - but something 99 of 100 Cobras owners probably would not do or care to do. So, it just depends, some folks like to do something different just because they can or want to be different. You can put two R1 Yamaha motorcycle engines in an Austin Mini Cooper and it will go like crazy too, but may not be for everyone.
I'd say once you figure this out with more certainty, you can make just about anything work with desire and willingness with customization. Good Luck.
