What don't you like about the 3:73's

They don't give me enough rpm at 70 -75 mph on the interstate. They dont let the water pump spin fast enough at 70 for max cooling. The things I do like about them is they are great for the little bit of city driving that I do and you dont need the extra transmission speedo gear like you do for the 4:10.
