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 **** yourselves, and possibly learn a little bit about engine technology at the same time.
K, I'm done and ready for the sanctioning......

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.

Basic answer is that the Cummins is just a tougher engine than the Powerstroke is, but also it's not smaller than the Powerstroke, yeah it has 6 cylinders, but the displacement of the two engines is nearly the same give or take a few cubic inches. In stock form they're basically all tuned to be within 10hp/10ftlbs of each other to stay competitive, but once you get tuning big, that's when the overdesigned internals of the Cummins really shine through in terms of potential power numbers.

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.
