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

Looking through old magazines....SS & DI Dec 79. Article on long & short rods. Apparently at that time there was a junior fuel Chevy class. Ran fastest with a 1.9 r/s ratio, but et'd best with a 1.75 ratio. Junior fuellers were limited to 310 ci & had NO transmissions. With a 1.9 ratio, they would run 198-199 mph. With a 1.5 ratio, these turned about 185mph but regularly et'd 1 or 2 tenths quicker.
