I have an 88 Mustang with auto transmission and I was wondering what gears would be better for my car.transmission was rebuilt 3000 miles ago and car is a stock daily driver with minor boltons.

4.10's

With 4.10's @ around 70 mph you should be @ 2 thousand rpm's , maybe a little higher . but yea they'd be a great addition

You need to consider your plans for the car in the future. If its gonna stay N/A 4:10 would be a good choice.

Possibly looking to add a vortech v1 in the future so should I go with 3.73 instead?

nah , 4.10's are fine dude . I think your car would benifit most even with a blower from the 4.10's . although you may consider a beefier input shaft , torque converter and valvebody for your tanny for even better performance and firmer shifts once you install the V-1.

Why not 3.90's?
 
Posted by Camara90 (Member # 134) on :
 
if you are going to stay stock heads, intake, and cam with the blower the 4.10 will be ok, but if not I would do 3.73.
