you go through the revolutions a little quicker, and you pretty much no longer have 1st gear.

with the 4.10s you would be shifting considerably faster under WOT...you would still have plenty of 1st gear uner normal driving conditions and it would just appear a lot shorter under WOT as you would be reving through the rpm range/accelerating faster than 3.73's or the stock gears. As said before "dont fear thge gear," the only reason to get a smaller (3.73) gear is if you have future apirations to have a large power adder and put some serious numbers down. That all being said, get a set of 4.10s n they'll bring a smile to your face the first time you jump on it after the 500 mile break in period.

500 mile break in period is a myth!

How often do you go on the highway?

FRPP is ford racing

4.10s wont hurt your mileage too much. if i baby my car i can get 20 mpg which is pretty good for a auto GT with gears and 42# fuel injectors.

Why do you have 42# injectors? Are you spraying?
