3.73 or 4.10 for the 6 speed?
I've noticed the past couple days 6th gear with the 3.31 rear end in my mustang runs at a higher rpm than on my old firebird with the T-56 and 4.10. Going 70-75 it's about 1800 rpm whearas the firebird would be loping at around 1300. Is a 4.10 just too much to keep the rpms in the gas saving range on the highway? The car isn't my DD, but I'd like to retain the significant gas mileage advantage over my Z71 for road trips.
