Builders: Square engine, Over Square, or Under Square for you?

It seems Chrys recognised that for engines that go to higher rpms, & work in the high rpm range, a long rod is better; for the 426 hemi, they lengthened the rod when they already had the shorter wedge rod.
The gains they saw a most likely in the reduction of piston skirt length, rather than the 0.02 increase in Rod Ratio.
