How to make a supercar slayer from a tired Ford V10?

Some people can be satisfied by swapping in an LS or a 2JZ into their project, but forum user BuildItYourself isn’t most people.

Instead, the plan is to take a well-worn 6.8-liter Ford V10 from an F-350 and turn it into a four-valve, high-revving powerplant fit for a supercar.

Seven episodes of the build series are already live on YouTube, and you can watch the first one here:

I suppose you have to give them credit for trying something different.  Personally I would have either gone with the 2005-12 V10 with the much better 3-valve heads that were factory rated @ 360 cHP and 460 ft-lbs of torque and did some "normal" hot rod tricks or gone with the supercharged 5.4L 4-valve out of a Shelby GT500 rated @ 500-550 cHP and 480-510 ft-lbs depending on year.  To each his own wink

The 6.8 is just a 5.4 multiplied by 1.25, so making a 4V version of the 6.8 should give similar improvement to the gains seen on both the 4.6 and 5.4 4 valve (over the 2 and 3 valve versions).  As long as the crank holds up, it should make that much more power than equivalent treatment on a 4.6 or 5.4.

Nomally I'm of the opinion that more cylinders sound better, but there's something about V10's that usually just disappoint me. That is... until they cross the 7k rpm threshold. Then they take on a totally different character. Audi / Lambo, Toyota, Porsche, BMW, any of that era's F1... love 'em.

So this is about cool-factor more than performance gains? Cool!
