I'll even spot you the '08 V10 powerplant numbers:
HP: 362@3250RPM
Tq: 457@4750RPM
Now turn the way-back machine to 6 years ago and the last of the 7.3L's:
HP: 250@2800RPM
Tq: 525@1600RPM
If you want a hot rod, then the V10 is the way to go. If you're old (like me) then it's all about the grunt, and that's why I've got the 7.3L.
Even though the V10 delivers only 68lb-ft less torque (you're talking 650lb-ft out of the new diesels), I'm getting all my stump pulling power to the ground at 1600RPM (not much off idle), throw in 17 mpg and I'm sold!
If you don't actually need the truck, then it comes down to personal preference. Unfortunately it's hard to get an unbiased opinion. It's like going to your first school dance with all of the boys on one side and all of the girls on the other and nobody talks to each other. When it comes down to it, a Super Duty is a Super Duty. I just happen to like pulling into a fuel station and only having two nozzles I can use (and usually have to wait behind some woman who can't figure out how to fill up her Yukon), being able to smell my engine while I'm driving it and having people turn their heads as I drive down the street because they think the garbage truck is coming.
Not to mention that with the second alternator I have 220 amps of service available.

Forced induction has a funny way of doing that.

So you must be saying because the 7.3 has a turbo it makes it a superior powerplant!

See, I just don't get the RPM arguments. I can get a 20,000 lbs load rolling with a V10 or 5.4L truck, but maybe not as quickly. Is that the argument? If so, what about after it's rolling?

I've never really understood why people are afraid of the RPMs. Why is it better to top out at 1600 RPM? What if you're pulling a trailer through the mountain passes and your trying to pick up speed? If the 7.3L you're talking about reaches 1600 RPM it then drops off, right? So, say you are driving over a pass and want to pass a vehicle, wouldn't it be better to have peak numbers at a higher RPM? Are 7.3L only good for pulling stumps? What about once you've pulled the stump and now you want to take it somewhere? So, the 7.3L is better at getting rolling under load, but once you're rolling you're getting passed, right? Or, is the 1600 RPM good for getting the load going, and then you just keep going and going and there is not strength in having the peak power at a higher RPM.

Maybe someone could post a dyno run off of a V10 and we could see how it's torque curve compares to that of the powerstrokes.
I know the powerstroke's curve peaks early, but the curve is fairly flat. I suspect a v10 curve is much steeper, but I may be wrong. It would be nice to see some actual dyno numbers, not just Ford charts.

If you multiply the gear ratio ( with both having the 3.73s and 4r100)
It is like this
7.3 = 1390 pound feet to the ground
6.8 = 2625 !
BTW, my 6.8 has a 200 amp alternator.
