A buddy here in town has about the same mod's as I do but still has the 3:73's and I walk all over him now!!

Having 4.10's opposed to stock gears, you will get better MPG in town, if you don't goose it at redlights or every chance you get. Having the numerically higher gear takes less strain for the engine to turn your tires and get your car to start rolling from the red light. But..sometimes it will take a little from your gas mileage on the highway and sometimes it won't. I chose 3.73's only because i might go with a power adder later and don't want to finish the quarter mile in 4th gear pushing 6K RPMS.
