I read an article maybe in old cars awhile ago that showed the figures for Ford vs Chevy sales numbers. Almost every year after the model T, Chevy bested Ford. Every few years Ford had the upper hand but Chevy would bounce back. However its not like they were outselling by huge numbers. Both had very high sales figures and were running neck and neck. Having said that I would could only surmise why model A's seem to outnumber compatible Chevys of the era. Perhaps the same reason that the tri five chevys seem to outnumber any other make from the 50's. Popularity.
