Becasue it has less moving parts than a V8....

(psst: did anyone hear a *pop*)

You're funny

all the big truck manufacturers made a v8 cat cummins detroit etc. like the majority of the people on here already said the fact is the inline 6. it cant be beat my buddy had a f-150 with a 300 straight 6 with 400,000 miles on it. the inline is just an indestructible motor thats why i cant understand why ford and chevy havent followed suit yet and made their engines inlines.

I just love the B series "super truckers" and their mighty mouse baby big rigs.

A B series Cummins is medium duty....as are all of the Navistar V configuration engines used in the Ford trucks, and since the 6.6 Duramax is used in the larger GM trucks I would assume it is medium duty rated as well.

The "light duty" urban legend about the Powerstroke emission sticker is complete bullshit. The sticker says "light heavy duty". The 7.3 and 6.0 Powerstrokes are AKA the T444E and VT365 and are used in the International 4000 series trucks all over North America.

And seriously, if you've ever been around stationary power gen equipment, the marine industry, or very large earth moving equipment...well, the amount of V configuration engines you see would make you shit yourselves, and possibly learn a little bit about engine technology at the same time.

K, I'm done and ready for the sanctioning......

Mr. Miyagi's Sig:

V engines in equipment? Naw.......all lies. The 657's, 637e's, D10's and 777's never used 3408's or 3412's. Never......NEVER!!!! I won't believe it.

IT SHAKES RATTLES AND ROLLS

The Cummins KTA series was a myth made up on the internet, and Al Gore never did invent the Caterpillar D399.

Also, the Caterpillar 3516 is only an internet phenomenon as well....it was never built, because Caterpillar knew it would never work cuz their engineers read all the diesel sites to learn what is really going on.

the Cummins is alot smaller then the 7.3. 5.9= 360CI 7.3=444CI so thats alot in my book. the dodge has about 60CI Vs 55CI in a 7.3. and the dodge can deliver more fuel do to fords injection system witch sucks. good idea but you can only push so much threw a HPOP. im a ford guy all the way but that 5.9 is a darn good motor.

It should also be known that the HEUI system is not a Ford system but a Navistar system; a system that was a joint development venture between Navistar and Caterpillar.

Now how does that work? The guy I work with bleeds yellow and HE swears up and down the the HEUI was developed entirely by Caterpillar(along with every achievement of the modern world) Just curious if you know more of the story than I do.

cat still uses that system dont they if i remember rite? ill still take by b series 5.9 over any of them and my 855 cummins in my big truck over the rest

Mr. Miyagi I am still interested as to why an Inline motor is perceived as more reliable than a V8, I'm assuming that their are indeed differences and positives and negatives to both designs and I'd really like to know your stance on why things are the way they are, there has to be a reason these "stereotypes" exist I know I have my opinions on this and I will share them upon you stating your opinions, to me it seems like an inline is better and more efficient and reliable up until a certain size threshold where a V just makes more sense because of the amount of space an inline would take up

what i think he is saying is that ford did not build the powerstroke, navistar did and there all HEUI systems

i know what mr. miyagi is saying by the HEUI system it was a joint venture by navistar and caterpillar and it's cool that they worked together on it, the question i'm asking is why is the inline motor "better" than the V8's in today's light duty pickups

I never said one engine was better than the other; I was only commenting on how ridiculous it is that many people automatically assume the Cummins is far superior over the V8's purely because it is an inline 6.

Diesel engines come in many configuration and there are lemons and diamonds in each.....using limited examples and knowledge to form an opinion is foolish.....that's all I am getting at.

One could debate the best engine configuration topic for days on end and have enough supporting knowledge and factual information to come up with the fact that neither design is ultimately superior---they all have their benefits and shortcomings.

---AutoMerged DoublePost---

Caterpillar is very tight lipped about most everything regarding their designs, data, and development programs.

Navistar and Caterpillar have been working together on engine development projects for over 20 years. The HEUI system was developed by a joint design and engineering partnership and brought to market by Caterpillar first, and Navistar shortly thereafter. It is now used by a host of other manufacturers, many of whom are involved in working relationships with Caterpillar (ie, Perkins) and other manufacturers who market other people's engines under their nameplates. Ever hear of the MTU/Detroit Series 30 and Series 40?

Keep a watchful eye for Caterpillar to return to the on-road heavy diesel engine market in a similar manner; standing slightly behind and to the left of their old friend, yet heavily involved in the process.
