Chevy went with the smaller gear to avoid the gas guzzler tax with the bigger engine. ~$2000US to change it. Match the Mustang 3.73 screw and you will cream them from the word Go. With the stock gear you will pull on the GT after ~70MPH (3rd gear).

Then why are the gt's putting down slightly faster 1/4 ETs and traps if the SS is going to pull on them after 70? They still seem to have a small lead at over 110. Besides that, the fastest 1/4 numbers to be put down have been by 5.0s with either the 3.15 automatic FD, or the 3.31 base FD for the manuals. 3.73 cars are actually the slowest in the 1/4 because it necessitates another shift. Doesn't support your theory here.
