Un-stroked vs Stroked Displacement vs. Crank Angle, etc.

I always have been curious about more or less stroke motors. An example my dad has a 1976 318 ramcharger. I have a 360 dodge dart sport. His truck seems to rev up quicker and easier sort like a 340 (sadly I have not had the pleasure of driving a 340 car :(). My car feels very different as compared to the truck. Hard to explain but that is my experience.
