I don't mean for it to seem like I'm picking on you or anything. You're just posting quite a few things I want to comment on.
As far as math problems, I've posted a little (at least some equations), but I've done a lot more checking stuff. I'm not at all afraid to post stuff, but from my experience, when most people see lots of numbers, their eyes glaze over and they zone out until the next post anyway. Unless you want video from a Thunderbird with a 2V 4.6, I have nothing to offer there. I found this thread looking for info about the different engines.
I was really hoping that you would post the numbers including a rear end gear. Using those, the 5.4 would come out slightly ahead for peak torque in 1st, but not in other gears. But that was leading to another point, more about transmissions than engines, though. When comparing 1st in a manual to 1st in an automatic, people seem to leave out the torque converter and torque multiplying characteristic. I think multiplication peaks at stall speed and drops from there, but that is a big difference in getting a load moving initially. I think the converter multiplies 1.8x in the 5r100, which also happens to be roughly the ratio between 1st gears in the manual and automatic that is offered in these trucks. Coincidence?

When I read things like that from you, you know what word comes to mind?
Yes, I understand that. We are talking about the tests Ford did when they designed them. Not what they did to every V10 that came off the line.
As long as Billy Bob did the most basic care during that 5 years, it should not have any trouble doing the same tests.
Well, the one spent a large part of its life with sludge for oil, so it has no hope. You already know that though.
The one that I have worked so hard, but also done all the maintenance on?
It should have no problem doing anything it could new.
I can see (for instance) an Eco-Boost being pulled off the line and being repeatedly dogged in different tests. I would hope it passed as it's brand new. I'd like to see them take one that's been driven by Billy Bob Redneck for 5 years and do the same test. 10:1 says it would blow up.

Along those lines, my '04 crew cab/sb V10 weighs in right at 7,000 with 1/2 tank gas and it has a shell that likely weighs 300 lbs (?). Is there that much of a difference between the PSD and V10 engines as far as weight?

Of course...an engine would never just wear out...It can always be traced back to a lack of maintenance, right? I'd like to see you pull your other engine and run it through the same tests...$20.00? Awwww...scratch that, I'll offer you $50.00 to do it. Maybe 200140ex will match my oh-so-generous offer

The way Ford tested them? I would rather not, thats enough to take a brand new engine and just about wear it out.
It would need an overhaul after that.

You did notice the 7600lb empty right. 7900 lb is with tool box.

Man, where did you guys get these skinny trucks? Mine weighs 9,400# with a full bag of diesel and me and nothing else.

I know it was a typo, but you wrote 79620 as the weight with the toolbox. that would make it one heavy truck.

No, you didn't go 20 minutes...but not that test... I'm talking about pulling your engine, hooking it to a dyno, and running it full tilt for however long Ford does, then shocking it with cold water, lather, rinse repeat, or whatever they do. That test. Your engine WILL do that, right? I think you said it can, so prove it. And before you say something like "pull yours and run it next to mine", the answer is "no" because I never claimed mine could do that...and if they did test diesels that way, at 8 months and 18000+ miles, I doubt mine would pass anymore.
