The 7.3 gas engine is really no different than most typical pushrod big blocks. And like most pushrod v8's the stroke is shorter than the bore size.
Toyota took a better stab at a true truck engine with the 5.7 as the stroke is longer than the bore diameter.
The other 7.3(powerstroke), same deal, the stroke is longer than the bore diameter.
It's very rare to find a V8 that is designed for low end torque right off idle.
It's why inline 6's are so dmn good in a truck, like the 6bt Cummins.
