Is it the valve area per cylinder volume or is it the balance aspect? You can increase valve area by shortening stroke and increasing bore, but then I guess there are combustion issues when the bore gets too big or something.
I believe 6 cylinders are used in luxury cars because they are smoother, and I've heard that the reason for V10 and V12 rather than a fat V8 is because of better balance or something, not sure. They sure do make a great sound
