Not Ranked
I've always maintained my part of this debate in the context of a general rule of thumb. I also understand your premise Brent, but would ask when you say a lot of big blocks have lighter rotating assemblies than small blocks are you talking unmodified OEM to OEM motors? If not, are those BBs built with exotic light-weight components + whatever tricks you have up your sleeve to lighten the rotating assembly that beat the OEM SB? Seems to me if you use the same exotic light-weight components + tricks your SB build will have a rotating assembly correspondingly lighter which puts us back to square one.
