your the same guy that won't powershift.. you need too get yourself a ****box 95 taurus too get back in forth too work. . thats what i did.. now i have fun with my stang. performance cars break.. unless your car is a garage queen that is never ran.. and if you never run please sell and buy a v6. then you can have a stang and not have the uneeded burden of parts breakage. 4.10's is more fun than 3.27's thats why i ordered them.. i would have gotten them a long time ago but i am poor. if it was up too me the mustang would come with 4.10's 4.10's offer improved acceleration. less of a load on the engine so it might last longer. and in real world driving of traffic lights and hills you will get better mileage. load percentage has a bigger impact on mileage than rpm's if you don't belive me get a 96 or newer mustang and use the WDS ( scan tool at ford dealers) and do the fuel economy tests. this gives you a real readout. and you will see how load effects mileage. highway MPG will drop slightly but around town you will stay the same or gain.
