The industry's terminology is kind of confusing. A numericly lower number is actually a higher gear than say a numericly higher number. What the number represents is how many times the driveshaft has to turn to turn the wheels once. In other words with a 3.27:1 gear the drive shaft has to turn 3.27 times to 1 turn of the wheels. If you have say a set of 2.98:1 it will take fewer revoltions to do the same amount of work, however it requires more effort to do so. The opposite is true of a set of say 4.11:1 gears, it take more rev's but less effort. I think because you are using an AOD trans, 3.27 should work OK. Sorry for running long,hope this helps you out.

So what does that say about my 2.79? I'm going to be putting in an AOD also.

Believe 2.79 will be to tall. Check out this site and you'll see that 2.79 won't allow the motor to run at a good power range when in OD. Check out the RPM calculator.

In my opinion you want around a 3.5 gear with OD. I had 4.11 gears with od and it was great.

Good luck

I believe 2.79 gearing was standard on 89-93 Mustangs with AOD. 3.27 gearing was a no cost option offered to dealers and most accepted ( the cars were peppier on the lot and who realizes the mileage penalty until you own it) Anyway 2.79 is O.K.

Went and check it out. With 205/60/16's, it'll be running about [email protected] Doesn't sound to bad to me. I'll probably drive it for a while, and then redo the rear end. Thanks for the web address.
