poster except on one point.

v engines arent always smoother than inline.

an inline six is generally agreed to be the smoothest naturally of all the configurations.

a 60 degree v6 is very smooth too. a 90 degree v6 is not. it takes balance shafts or offset rod throws on the crank to achieve smoothness. 90 degree v6s are only built to take advantage of 90 degree equipment on hand for building v8s.

a v8 is pretty good.

a flat six is good, and a flat four.

a 60 degree v12 is very very good. (two inline sixes combined).

a straight 8 is good but the long crank is a disadvantage in stiffness and weight.

now adays with balance shafts i suppose you can build any configuration and make it smooth. v7 anybody?
