The video didn't say "inherently", but rather "typically" -- and that is correct: flat crank V8s do typically have shorter strokes in order to minimize the effects of imbalance and vibration. One of the things that I'm most curious about with this new Ford engine is just how bad the vibrations are going to be if it does maintain essentially the same stroke as is used in prior Coyote engines. That would be a very long stroke for a flat crank engine. On the other hand, if you were to destroke to about 4.5 liters, then the bore and stroke numbers would be very similar to those of the current Ferrari 458 engine.
