How could you have 350 hp at the rear wheels then say you have similar hp to a 3v V10 when a 3v V10 is rated at 362hp at the crank?

Do you even know how hp is achieved? It's calculated.
Sure your engine can twist a crank harder, but not nearly as fast.
That's the advantage,
Diesel's twist harder,
Gasser's twist faster.
You use gearing on a diesel to allow you to reach highway speed.
Yes, but less gearing than a comparable gasser.
It's simple, an engine with higher horsepower is capable of achieving more work.
Driver comfort aside, I prefer a diesel to tow heavy. imo it has superior towing characteristics.

2006 v10 362 FWHP - 301.7 RWHP (approx) About 380 RWTQ
My sig truck 384 FWHP - 320 RWHP (approx) at least 650 RWTQ
My truck will easily outrun and outpull the V10 (by way more than the 18.3 HP diff.) Why???

I'm assumming you mean at a1:1 trans ratio and the same rear gears? If so, thats the arguement is that gearing makes all the difference....

I was trying to say that if I have the same HP as the V10, I will out pull it. Easily.

On a level road, both engines will have more than enough power to move the truck loaded to max GCWR to the speed limiter of the truck. On a large enough grade to max out both engines, your truck would probably have a 2-3 mph advantage due to the extra horsepower.

Given the numbers you state, you will be able to accelerate through first gear quicker than a V10 due to the torque advantage. Due to your inability to rev as high as a V10, you will have to shift sooner, though, and your acceleration advantage then ends. However you will have a noticeable lead by this point.

Because you run out of rpm and your truck has to shift. Your inability to rev to a higher rpm forces you to shift to a higher gear if you want to accelerate to the speeds the V10 will reach.

Ok let's look at it this way, you don't like using gears in the discussion of which engine is more powerful?
Let's have a race, we use 3:73 diff if you want, and lock it in first gear on the transmission.
we can race for 5 miles, and see who crosses the line first.
Not fair?
Both trucks use gears and gearing to make them as useful as possible to suit the engine.
Diesels have more grunt, so they use lower gears to allow the truck to make the best use of the engines charastics.
The Gasser makes more power at higher speed, so it uses gearing to allow it to rev up a little.
Why does that make it weaker?

I love the BLOCK feature...I just wish it worked on quoted messages too!...the useless arguments people are making about gearing are something that is ridiculous...FORD gave the trucks gears and transmissions...why is it so difficult to understand that the FORD engineers KNEW the limitations of the engines and mated it with the PROPER GEARING to get the job done...
When was the last time you saw a motor alone laying on the road pulling a trailer?...how crazy of an image is that?...
To state that using the hardware that the people that KNOW and DESIGNED these motors is taking advantage is just plain foolish...
I do wish that my blocks worked on the quotes too...

Funny stuff in here!
It goes from who can pull a trailer faster up a hill to who has more hp to who gets the best mileage to who can get up to 70mph first.
V10's just need two more cylinders to get the same job done.

I agree! They all need gearing, but a less powerful engine needs more gearing, that's why the Ford engineers gave it more
When was the last time you saw a motor alone laying on the road pulling a trailer?...how crazy of an image is that?...
Duh.... But motor power has something to do with it, or why don't we all run 4cyl. with monstrous gearing?
