Probably a Dumb 318 Question

I mostly drive within my town which is pretty small but sometimes do freeway so I was thinking 3.73 is a good middle ground
People may hate this but, my other car is an 86 Mustang GT 5.0 with 2.73s and 5 speed. I can take that car anywhere highway trips cruises etc. That is just a plain old light weight 200 horse daily driver type fuel injected v8 car.
