    The crank is what makes the cylinders go up and down in a certain order. That way not all the cylinders are either up or down at the same time, creating a balance. Ferraris use 180 degree cranks, meaning at any given time 1/2 are up and 1/2 are down. This gives Ferraris their immistakable steady scream.

    Other engines dont have this, for fuel economy mostly.

    Easy example is listen to a 550 and listen to a 3xx cubic inch muscle car, or a vette. You will hear the almost thumpthump form the vette and a almost, as described my mechanic, 'jet turbine' like growl from the fcar.
