i only know of one instance where a 6 cylinder vs. 4 cylinder is actually benifical.
any 4 cylinder over 2l creates a secondary harmonic, that can distroy engines; harmonic balancers are needed along with heavier crankshafts.
where as the 6 cylinder needs none of that.
gm engines
2.5l I4 110hp; 2.5l v6 145hp; 2.5l I6 154hp
195ci pontiac I4 vs buick 3.0l v6
