So why did Ford with there all new 08 F 450 King Ranch ONLY give you the option of the 6.4 DIESEL. Why because they figure you towing a lot and want to give you the best combo. They don't even offer the V 10
On the F450 pickup they don't, but on a real working truck(chassis cab) they offer the V10 all the way up to the F550,and it's rated to tow EXACTLY the same as the 6.4L.

Let's put it this way... (I've explained it this way before, lots of times, maybe this time it'll make more sense )
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.
I miss a day and I'm several pages behind. I'm wondering how many pages this thread will make it to.
Anyway, all due respect, but we aren't talking electric fans spinning at a constant rpm. This argument is like a Minnesota Senatorial recount. You can't just tinker with gearing to get the desired outcome you want and then declare game over. You gotta let the other guy tinker too. But hey, it worked for Stuart Smalley.
I go camping a lot with a buddy who has the exact same truck as I do. Same year, same body, same engine, no tunes. Except he went and put in 4.30 gears. His camper weighs about 1k more than mine and he out tows me all day long. We don't go racing around but when we come to a mountain grade, he turns into the energizer bunny and leaves me in the dust. I normally don't tow over 70 but we've both been at 80-ish and he was just fine.
So the "the psd loses top speed" argument means nothing if the loss is still faster than you ever plan to operate. There is no doubt in my mind that the psd wins hands down with 4.30 gearing. So the question becomes, what if you went to 4.56 or 4.88? My guess is that the top speed argument would then actually become a factor.
Quickly back to the Caterpillar question, I believe that cat got an extension or an exemption from the EPA to allow them to continue to build truck engines for a little while longer. The bad news is that no one likes them. They eat turbos like nobodies business. The top turbo comes apart and pieces of it go into the bottom turbo,,,,not pretty. Cat will continue to take care of the engines that are still out there, as well as make engines for glider kits, which are reman engines usually.
John, I'd like to see where you get this from. Not doubting you, but haven't heard much since a year ago when they made that announcement.
As far as nobody liking them anymore, they did have lots of problems with their ACERT engines they introduced in 2004. Since then, I believe they've gotten much better. My work truck has a 2005 MY C15 ACERT engine, and it's been pretty good to me for the year I've had it. Still chugging along, at least for the moment!
I do know that my company stopped buying Caterpillar engines, and I believe it has something to do with the announcement a year ago that they were getting out of it. Nobody wants to own an engine that may or may not get good support from the manufacturer.

But the Diesel only needs 4.30 gears when the V 10 gas needs 4.88 gears to just do the same job thus the 6.4 is more efficient and towing.
