Title: Rear Gear Choice?
Post by: tbirdboy88 on September 19, 2008, 02:19:50 PM
Hello all, i just got a Ford Escape today for my daily driver.

Now i need some help on deciding on what gear to put into my 88 tbird, i was thinking 3:73

I do most of my cruising at 30-50MPH does anyone know what kind of RPMs i will be doing at 60MPH not in overdrive and also in overdrive??? stock motor and trans and 215/65R15 tires.

Also does anyone have more that 3:73, its an auto.

I am just changing the gear with the original 7.5 traction lock rear end.

Jeff

My combo: 306, 5 speed, and 3.73's @ 60MPH = 2000 RPM's
