I just finished it and it was very interesting!
It's the same thing that had been said for years.
You have to spin the HEMI hard to get it to run. Not so much with the 440 as it makes tons more low end torque.
Here is a screenshot of the runs overlaid. Red is 440, black is Hemi.
Sorry I don't know any other way to say this but If you increase the TQ per cube on the 426 to the same TQ per cube X 440 it is only down about 20lbs to the 440. The HP would also go up a little from the bigger bore unshrouding the valves more and the CID increase. Another way to look at it is you can always multiply TQ with gears but you can not multiply HP, what the engine makes is what it makes. In the same car with either cubic inch equal or gearing adjusted for the lower CID the hemi will win.
