Reduction in Hemi piston skirt length with the longer rod.......
The Hemi rod was less than a 1/10" of an longer the 440 rod. Doesn't make sense to use a longer rod, solely for the purpose of a 0.09" shorter piston that was already very heavy with it's domed top. Moving the pin up in the piston allows the piston to rock more & could lead to ring flutter or unseating the rings.
The fact is that Chrys already had a very beefy rod in the six pack rod....but chose to go to a new forging of a longer rod.

It’s over most people’s heads. Even if it is explained well and on simple terms, most people here are just general hot rodders. Getting into a deep dive is t in most peoples wish list.

Indeed it is.
I enjoyed it. I like listening to the engineers and top notch builders, the fellas that push the limits. Even though I’ll probably never get to build a 2500hp NA engine, it’s interesting to follow along and learn something.
For most people it'll never really matter, because they couldn't care less about every last ounce of power or speed.
Is there a better combo than the 451.
I'd say it depends, say you bore a 400/440 out to 4.375" and put a 600-800 hp top end on it, to me the question is where (rpm wise) do you want to make the power 3.38" high rpm or 4.50" 2000 or so rpms lower or somewhere in between.
And even if you want more power it's generally cheaper and easier to build it by slightly less efficient means.

I prefer the oversquare myself, bigger bore makes the heads happy.
Here’s a picture you can save and use next time you want to give someone the big
