Why a v8 diesel?

I was just wondering if anyone knows why ford/international went with a v8 diesel insteed of a inline-6 like the cummins and all the big rigs? The inline-6 must be a good design because they use it in all the big rigs, so is there a benefit to a v8 design?

A V8 is more compact and lighter for a given displacement. In a pickup this is a big deal, but in a big rig they have a ton of space under the hood and weight is not a factor either as it actually contributes to the stability of the truck.

Many people like the Cummins and make the comment that they would buy the engine if it didn't have a Dodge wrapped around it(grin). I can relate to that comment because a friend of mine is DieHard-Dodge and drives the Cummins. He has more problems with trannys,electrical and A/C, but never with the engine.

I think what duffman77 said also has something to do with the answer. I'm sure FORD and GM don't want the same engines as their competitors(grin). I have noticed how rough my buddy's truck runs compared to my V8. It could just be the Dodge though.

I can attest to that. My old truck which was an 02(old body style) 3500 dually rode awful, but it had tons a power and I never had fault the need to boost it with a tuner like I did with the ford I have now. However, I was a little scared when coming from stop signs or stop lights, the transmission had a hard time finding the right gear and haulin butt oughta the oncoming traffic, and unfortunately traffic comes pretty quick down the road if you don't watch it. Now I didn't have an a/c problem, but I did have it with the ford, but I'm willing to bet it was because the a/c in the dodge wasn't digital like it is in the ford. Now my dodge was lighter then the ford I have now, so I don't know where the idea that dodge weighs more due to the type of engine they have. I also had them pile everthing they could onto that dodge like I did for the ford, so they were are almost identical with the exception of the spanish leather and the ford also has more creature comforts then the dodge. But boy did that dodge ever ride rough, particularly over I10 when you go over the basin, it was like driving on a washboard.

A V8 is more compact? Have you ever looked inside the hood of a Dodge with the 5.9L Cummins? You could practically sit inside the engine compartment there is so much spare room. My 6.0L PSD has been a home run but I think Ford would have had a grand slam had they the ability to use the Cummins.

Not true. The Cummins B series engine, which is the motor that Dodge uses, is a commercially available engine, that comes in a few different displacements. Dodge will continue to use the 5.9L in it's light trucks for sometime. The 6.7L is used in some medium duty applications, and in agriculture. It is not a new engine.

So besides it being lighter and more compact is there any power advantage,rev quicker or higher, or more bottom end, or smoother power or anything like thay?

Alot of people will tell you that the inline configuration is good for producing torque. I think that is more coincidental to the fact that during the 50s,60s,70s that inline 6s were used as the base engines and thus low rpm engines as opposed to the high performance optional V8s. Because it has 8 cylinders it could be smoother but an inline 6 can be perfically balanced, so the difference is minimal I think.

Yes. I checked out all 3 truck brands very carefully before I bought my 2006 F350. I have some pretty meaty (ok fat) arms and could fit them easily in the engine compartment of a cummins. I don't think I could fit my index finger in most spaces of my Powerstroke. I still love the truck anyways and have had absolutely no problems with it so far. I'll let the Ford techs work on it though. I think working in that engine compartment would sour me on the truck which I definately don't want. I'll just drive it and wax it.

Now that is funny. Very true for me, other than the preventative maintenance all I've done is wash, wax, and drive, drive, drive. In my opinion the preventative maintenance is fairly easy, if I can accomplish it then it must not be too difficult a task. The oil, fuel filters, everything is doable for the average home mechanic.

Yes, but how would you like to replace an alternator or radiator, or better yet swap a new motor in there? I don't think it looks like a whole lot of fun. No matter what I work on I find myself cursing the engineers that designed it. Sometimes you really have to wonder. Mechanics must curse them all day long. I don't blame them. A little more clever engineering and all these vehicles could be a lot easier to work on. I remember changing the spark plugs on my 99 F250 triton v8. What were they thinking? Unbelievable. I changed the 4 easier ones and then took it to a local garage. They said no thanks, we did one of those already.

Ok, I'll admit partial defeat. When I was researching this back in August, everything was pointing to not putting the 6.7 in the light trucks. If you have contradicting info, then I will concede my side of the arguement. At the time, all that I could find lead me to believe that the 6.7 being offered was purely wishful thinking of loyal Dodge customers. I should have stated that in my original post.
