Why do you Cummins guys want more gears
I’ve heard a number of Cummins fans saying they are waiting for an 8 or 10 speed transmission before getting a new truck. Why? Does the Cummins struggle to get your trailer moving from a stop? Or are ...

I-6 vs V-8 is a race is no contest, the V-8 will win most of the time due to a shorter stroke and less rotating mass. When we bought our RAMs(three of them) it was to tow trailers not race.
You can have a square I-6 and even a short-stroke I-6. Just as you can have a short-stroke V-8 diesel like the Duramax and a long-stroke V-8 diesel like the Powerstroke. There have been many short-stroke inline-six throughout automotive and even aeronautical history. In fact, one of the most popular GM straight sixes, the I-6 302, is a square engine.
The reason why each of these diesel engines makes different horsepower than each other has more to do with their turbo size, fueling, emissions/heat mitigation, and whether they are tuned more for short burst power or sustained power. Engine configuration is way down on the list. I would bet that if you put the same fuel pump, turbo, and tuning on all three, they would be within 10-15 horsepower with one another. Heck, they are within 10-15 horsepower from each other with just max effort tuning alone which is a clear indication that some are tuning more conservatively than others.
