Seems odd as I THOUGHT 09 was first Super duty available with 3.55s and it was an option.
I like 3.73 on a diesel myself. 4.30s if I was ever to pull 24k F450 style

Furthermore, as to the comment on if they hook chains to each other, it's meaningless! That particular pissing match hinges on traction way more than power. A PSD truck, with it's ~800 lbs greater weight, will ALWAYS have the advantage there.
Take a 5.4L F250 and throw 3,000 lbs in the bed, and try again. You'll find that "weak" 5.4 dragging you around the parking lot.

I havent hooked chains since i loaded the tunes, to cheap to wanna break somethin.lol I was just stating that when we hooked chains i drug him. No it wasnt an even match but thats how they both came from the factory.

Good one. This guy just claimed that he could pull a V10 truck that was "equally matched" around, but his truck has who knows how many HP worth of tunes on it and has optional towing gears whereas the V10 truck has the crappy stock gearing. He theoretically could have been running a 150hp tune at the time, making his little bragging session a load of crap. The V10 truck has the "economy" gearing and is lifted with 38" tires, any fool that does that and thinks his truck can pull around any other truck is just that, a fool.
Redneck logic isn't really logic at all. Its lunacy.
Unfortunately, gas engines need gear reduction to make torque as they tow with rpm rather than torque. Diesels benefit from gear reduction also, but with a lower numerical gear as they would run out of RPM at higher speeds. The optional gearing for towing on a 6.0L is 3.73. On a V10, the standard gearing is 3.73 (or was). 3.73 gears on a V10 was a gigantic mistake ford made until recently (4.10 is the standard now). The optional gearing for a V10 is 4.30. Had this guy had the 4.30 ratio gearing and an equal amount of power adding devices (such as a blower) the test would have been more accurate.
So in the end, the diesel guy just threw more money at his oil burner and proved just about nothing and bragged about it.

I paid much less for my PSD then he did for his V10.lol
edit: Did i say that i love instagating these little pissing matches.lol

Redstroker, I don't think anyone's offended by you loving your diesel. I really enjoy mine, it's a great motor.
But regardless, it's fun for the rest of us to debate these kinds of things. I learn lots by doing so...so instigate away!

I still would rather see a comparison with the same gearing. Following your logic to its conclusion, a psd with 3.73 gears will outshine a V10 with the same gears. Conversely, a V10 with 4.30 gears will outshine a psd with the same gears. I can live with that...but is it true? If the psd runs out of rpm at higher speeds, how much faster can the V10 go? 10 mph? 5 mph? 0.69 mph? If we only compared the trucks with "standard" gearing, we'd never know.
The only thing I am sure of is that a SD with either engine is better than anything Dodge or GM builds.

true, but the 6.0 and 6.4 do not compare to the cummins.

I just sold my CR cummins for a 6.0. While the cummins may be more reliable, they are completly different beast and hard to compare at all if youve owned them both. I loved my cummins for the big power, but with the power stroke the power is more "useable" for lack of a better word. I sold the cummins to my work and still drive it every day. When it comes to draggin trailers, cummins all the way. The PS will take more $$$ to make big power, but in my opinion the way the powerband is, less feels like more. I love both trucks but ford just makes a nicer all around vehicle.

but Dodge around it will hit trouble sooner than the others. Duramax Allison benefits from years of development. Ford needs to pick a diesel, pair it with a 6-speed and stick with it as they sure do make a nice truck.

I loved it. I was about to put twins and bigger sticks in it, but i decided to get my SD. It was quick. Runnin in the 14's, coulda gotten faster with more practice, but the nv5600 transmission wasnt made for racin.lol I just couldnt get past the interior, plus it was a drw and i felt like goin back to a srw. Pulls trailers all day now. Had 26K on the trailer and pulled like a dream.lol

)If you have a 1HP electric motor that runs at 1800RPM, and you need a fan to spin at a certain rate to make it push a certain amount of air, let's say you need to spin the fan at 600RPM, you pick belt pulleys that are in a 3:1 ratio.
If that motor burns out and you have to replace it with, say, a motor that spins at 3600RPM, but is STILL 1HP, you get pulleys that are a 6:1 ratio.
Gearing is different, both motors are still 1HP. Trick is, one puts out half the torque at twice the speed. Same HP. Same torque at the fan.
Same thing applies to gassers vs. diesel.
But in this case, it's torque-to-the-ground, where the real work is being done.
Both are good at what they do, and they both appeal to different people.
Same skin around the engine. A Ford.
