If this were a option I would pay extra for it!
For the record this is a Ford issue and has nothing to do with the engines this thread is about.
Every aftermarket programmer that I have contacted said that I couldn't use any of their stuff on my rig, for some reason the computer is different on the Cab and Chassis rigs, I've been emailing Edge and they don't have anything, BADP isn't even sure if their dpf delete will work on the C&C. :booo:

So you think the Cummins is better just because the inline 6 is a better design? Based on the fact that there has been other 6's with a good record?.....The same could be said about the V8 design too.
I don't work on them, but I think the weaknesses of all the engines are the smog and computer crap, we never had issues with diesels in our tractors or equipment, heck they would run on anything and last forever.

We were 1 repair away from getting a '05 F450 Lemoned, Almost had to take Ford to court
This thread isn't about F-450's it's about engines so why don't you tell us what the problems were with the engine?

The inline 6 IS a better design for diesel engines than a similar displacement V8 engine. This is because an inline 6's longer stroke takes better advantage of how diesel engines operate relating to their high compression.
Why do you think the majority of medium and heavy duty over-the-road trucks have inline 6 diesels instead of V8 diesels? It's been done this way for decades and V8 diesels have been tried and discarded as a viable alternative to inline 6 engines.
I read a story on a forum some time ago about two 18-wheelers leaving their yard with the same load and had the same destination. Both were very similar except one had an inline 6 and the other had a V8. The V8 equipped truck pulled ahead of the other truck in the beginning on the flat stretches of the Interstate, but once they hit the hills, the other truck caught up and pulled away.

Someone "endorsing" something is a matter of personal preference and that's fine but I would like to hear the reasons for the preference...

There's nothing that says a inline 6 engine must have a longer stroke. Lets hear some actual numbers....
I'm not saying one is a better design than the other but don't assume because one is used more therefore it must be better. In my OPINION 6's are used more because they're much cheaper to make.
That's a stupid story. Power is power and if one has more than the other it will pull better on flat ground or up hill. It's urban myths like this one that make people have "personal preferences" based on myth.
Besides this thread isn't about trucks it's about engines.

Thats comparing a detriot to a cummins/cat, thats a totally different story.:redneck:
I believe big diesels are straight 6's becuase of packaging issues.

I'm a fan of my dinosaur tech big block gasser. :awesomework: Diesels are stinky and expensive. :kissmyass:

Ford 6.0 V8 diesel--95.8mm bore, 104.9mm stroke = 0.91 ratio.
Cummins 5.9 I6 diesel--102.1mm bore, 119.9 mm stroke = 0.85 ratio.

Binder, I don't know what you are after here. But I don't see why you are trying to fight it so much. People don't buy Dodge's with the cummins in them, or swap a cummins into their Ford, just because it's the cool thing to do. Go out to the powershop, or DDP, any of the diesel shops in our area. Ask them which one keeps the lights on in the shop.
Jaydog.. I'll see what kind of info I can dig up on the C&C.

I'm not after anything other than reasons why people are loyal to one engine or the other backed up with facts. Yes I do believe it's mostly due to it being the cool thing to do.
If you have more FACTS to add we would all like to hear them.

Good to see some facts for comparison. I'll add the 7.3 stroke is 106.172 mm.
This however has nothing to do with the argument that inline 6's are better than V8's because the 6 has a longer stroke because it's not always the case.
Semi-Random post...
Power output being equal, personally I'll take a I6 over a V8 just for durability reasons. Hell, I'll even take a bit less power if I know I can bank on it taking all the abuse I can throw at it.
Most (including cummins) I-6 cranks have a main bearing on each side of each piston... V-8 cranks have a main cap on each side of each pair of pistons. Better support, more bearing area, and better oil control in the bottom end in an I-6 (that's why the old 6s ran for so damn long). The rest of it (injection system, aspiration, etc) changes year to year and can be modified. The bottom end configuration is the same no matter what else you do. I prefer the most stout bottom end I can get, and set up the rest to suit.
But that's just my $.02
