so the 5 speed no matter what came with 355?? Ford says 3.27. well then 3.55 to 3.73 is a waste 4.10 is the way to go. So all of them come with 3.55. Anyone have the gearing?

The car has the TR-3650 tranny in it. With 4.10s your looking at just about 3k at 80mph. I rough estimate is you will run 600rpm higher then it does with with 3.27s.

I know a few guys with 99+ and 2 of them have 3.73's and both said it was a total waste. On the other hand, the many people I've seen with 99+ gt's seem to love the 4.10's.

4.10's for sure IMO!

if it's a GT, it doesn't have 3.55 gears, it has 3.27. However, the Cobra's have the 3.55 gears. I have a 2002, with 3.73's in it, and I am going up to 4.10's next week.

My car's an 01. You will need to get a dallas mustang speed Cal. It's easy to install. Also the rpm difference between 3.73s and 4.10s is 300rpm. If the car is staying NA then I would go with 4.10s. If its going to have a power adder then I would go with less gear.

95 Gt's depend on what tranny you have if it is an Auto I believe they have 3.08's if its the 5 speed then they have 2.73's . [BS flag]

You might be bigger than me ,but I aint afraid to run from you .

That sounds about right, and yeah 5th has pull. W/ stock gears, 5th is only good for cruising. If you want to pass someone, you have to downshift. With 3.73, or 4.10's you can pass.
