Some of the caterpillar I-6s in semis are about 14 litres....

 

Who cares what the displacement is if it puts out as much or more power? The 6.0 PS is rated higher than the 7.3 PS in both HP and torque. It barely edges out the 5.9 Cummins by what, 5 or 10 HP and torque.
I know a mechanic that works for Cummins. His opinion of the 24 valve version of the engine is that it's junk compared to the older 12 valve. My Dad had a '96 Ram 2500 with the 12 valve Cummins. It would pull a trailer all day long without any problems, or he could cruise down the freeway at 70+ MPH and get better than 20 MPG. This in a truck that tipped the scales at over 7000 lbs.

 

The Dodge with a Merc diesel rumor has been around since the first word of their merger leaked out. If anything, they will use a VM Motori engine (read: Detroit Diesel), another company they own. They are already using one of those engines in the Jeep Liberty diesel, and in just about every other diesel vehicle they sell in Europe. But I doubt it. Dodge=Cummins, Ford=Powerstroke. Both companies would probably lose sales if they switched things up. I mean, who would want a diesel engine made by they D/C owned Italian company building Detroit Diesels? Or anything that can be traced back to the old Mercedes diesel cars? Yes, Ford would probably see more sales briefly from former Dodge owners, but they would probably lose sales later on, as service and support for the PSD suffers. A company that changes too much too often dies. If the PSD falls away, and the Cummins picks up, what's down the road a bit? A baby Cat? And then no service on the Cummins engines..........

 

The way I understood the transition is that International has had the 6.0 for a while and Ford chose to use that engine but they did not design it Navistar already had it. Ford wanted to make some changes to it and Navistar made the changes Ford wanted for use in their pickups. I think Navistar sells the engine to Ford and made the changes Ford wanted so they could continue to sell them engines. Ford didn't spend any money designing the 6.

There are a lot of "I think" 's in there because I don't know any of this from anywhere except what I've heard or read but I think that's what I've read in the 6.0 forum. Could be all wrong

 

The Mecedes diesel is probably stonger and quieter than a cummins in all honesty, Mercedes has been making them longer that anyone else, and I thought Detroit Diesel was a part of GM........

 

What should really happen is that Ford should offer it's customers a CHOICE: either Cummins or 6.0. If the 6.0 has problems that ford can't get fixed then folks can order\purchase a cummins . this way ford still sells a truck even though it sells LESS of the 6.0's. Then , instead of the custom taking the Hit on a defective truck Ford (because of declining sales) would go ahead and do what is necessary to fix the 6.0. As it stands now Ford gets to sell a defective truck , collect their money , then THE Customer is the one who has to keep jacking around with the dealership until the truck is fixed.. That is not right. sk

 

Detroit Diesel WAS a part of GM until Roger Penske bought the comopany in the early 80's.

 

I live in the town where Cummins builds the "midrange" engine. My father is in tight with a lot of people over there. He told me last weekend that Cat has done a few things that has upset Ford. Ford HAS approached the Cummins "Suits" to see about making the Cummins an option in a Ford. They will do it.

I know that Dodge bought Detroit Deisel about 4 years ago, and this town was scared, since 70% of the workforce is Cummins. As it turns out the Cummins is very well known and most folks buying a deisel will pick the Cummins over a Detroit Deisel. Dodge had to re-tool the Detroit Deseil factory and I believe it is an option, but the Cummins name is more well known and trusted, so Dodge has not (probably will not ever) break ties with Cummins.

When the economy dropped Cummins shut down for about 2 months because the Dodge trucks with deisels were selling, but the gas trucks were not. Dodge would not buy any motors off of Cummins until the car lots could be cleared out of the gas trucks.

BTW, I don't work for Cummins and could care less if they never sold another motor as long as I lived. Meaning, I am not trying to promote anything.

 

what i have heard is that CAT, International, and Ford came together to make the 7.3 powerstroke. CAT and International only wanted to use the injetion system. Ford wanted the whole thing. i can't remember where i heard that though.

 

Currently, Caterpillar is the only diesel engine manufacturer that meets emissions requirements for 2012. The 6.0 is a great motor. Give it some time. The 7.3 and 6.9 had just as many problems when they started. The duramax and cummins did as well.

International has had the 6.0 motor for almost 5 years now. Ford is responsible for the goof up in the injection system. They changed it to meet emissions guidelines. They changed the injector type and location. I don't recall what the valve thing was. I believe both motors are 4 valves per cylinder. There is a forum dedicated to the 6.0 and it is moderated by an International engine builder. The Diesel Dude knows a lot about this motor. I suggest that anyone interested should read through the posts there before posting rumors here.

 

Not true, Cat makes a lot of V8's too. I always wanted to drop a 3208 into a pickup but it weighs in at nearly 100lbs. Smooth runner though.

 

Yes some are but the "King of the Hill" is the C 16 which is sixteen litres. They claim it to be 600HP and tons of torque. Mmmmmm love them Cats.

 

I assume you meant 1000. I would think it would be closer to 2000 than actually 1000. 1500-1800#s most likely. The 7.6 internationaly is around 1500 and the 5.9 is around 1000.
Ok. So international is going to start building the mediums for ford. As in the 650s and 750s. Most likely they will drop the cummins altogether in favor of the 7.6, as in an inhouse engine.
Dodge has a contract with cummins for the rights to the 5.9 until 2007. No ford cummins til then.
The mercedes rumor has been pervasive. Not that its not possible. But its not likely.
The 7.3 uses technology developed by cat for the injection system i.e. heui. I assume cat had little else to do with the development of a competitors engine.
The 3208 is not thought of as one of cats best.
mattsbox. I was unaware anyone had met the standards. Do you have a link that I could read. This is a hotly debated subject and I would appreciate it.
The Diesel Dude has been hushed from what Ive heard.
The 6.0 has only been out for about 2 years. I recently read a report of problems with it in its vt365 format.
The 6.0 makes 20 more hp and 5 more lb ft of torque.
Some of the cummins I-6s are 23 liters.
The sprinter van is a foreign truck with a foreign engine.
No bruin ford used internationals engines. International actually manufactured medium and heavy duty gasoline engines. Tuff to say the least. Ive even seen a ford pickup from the early 80s with a cornbinder , i believe thats what he called it, international in it. The 6.9 engine block actually was another engines originally. Called the mv404. Its all in the roots.
much to my delight a lot of manufactureres have fiddled with v8 diesels. Isuzu has manufactured some of the most reliable for the US medium market.
