It's not
not really, basically line them up at there peak hp's (323 vs 367 vs 410) and see the powerbands are fairly similar to one another. The 367 only operates about 300 rpm higher through out the entire rpm's that's like one gear ratio deeper, eg.. 3.55 vs 3.91 and your both basically putting similar hp to the ground.
even if you widen them to 2,500 rpms below peak = all 3 are at around 250-260 hp
There only substantial if your gear them same. Cause again they make the same power just at higher rpms.
