That's Paul Stanchio's truck, the 12V71 would be a beast.

I best make this very clear as I just copied and pasted the add

 

The truck isn't mine and I am a different Paul on the other side of the world 

But to cool not to share 

If it was mine the Princess may very well find her self getting the boot for a bigger shed to fit more trucks in ha ha ha ha

I always have wondered about them. They are "only" 852 cubic inch, which is essentially the same displacement as a small or big cam 855 Cummins of the day. My guess is probably more horsepower than its contemporary Cummins and Caterpillars but probably equal or less favorable torque curve too. I would have to think they are extraordinarily smooth pulling engines. A 4 stroke V12 has a 6 power strokes for every crank revolution, or every 60 degrees. Versus 3 or every 120 degrees for an inline 6. A 2 stroke V12 is getting all 12 power strokes every time the crank turns, or 1 every 30 degrees. Like I said, I would have to think they are incredibly smooth and probably have a very different feel versus a typical I6. I would like to drive something with one it someday just to see but probably wouldn't want to own one. I have a friend who pulled very over length and overweight precast bridge beams with a steerable jeep in the rear back in the late 70s and early 80s when they were finishing the Interstate system around here. He ran a Kenworth with a 1693 and later a transplanted 855 Cummins of some variety. He ran with a guy who had a 12V71 in something pulling the same loads all the time and he says the two of them were always pulling grades at the same speed and they were about equal in performance. I have no other knowledge of their trucks' specs but that what his story. Have you every run one empty or loaded? If so what was your experience with it?

A 12V71 was 450hp or slightly less than 2 6-71's (238 hp). The 855 Cummins  was up to 475 hp in Big Cam but 400-450 was the best configuration. When it went electronic (N-14) power was much higher.

That said, in its time period it was one of the highest Hp engines people stuck in trucks, originally it was done as a industrial engine re-power, and later it may have been factory for turnpike doubles and the north slope oil field.

Never operated or worked on one.

The K Cummins (which I have worked on) was a better big power option. but $$$

Never ran one myself. That truck in the pictures looks like it may have been aa Allen Coal truck. There were a few and right up until only a few years back there was a guy close to here used one to pull his lowboy.  I was lucky enough to see it in action a couple times. I can tell you one thing, it wasn't crawl'n along when I saw it. He moved some big equipment too. They were hot in their day. If you wanted power back then, you got a 12V71 or a 1693.

Here is the FB link for anyone wondering. Facebook location says its in Binghamton, NY. The phone number indicates Long Island. The background of the photos look more like Binghamton to me.
