did 3 1/2 turns on my differential... what gear ratio do i have???

You have 3.27s and NO sn95 stang, I dont care what anyone tells you, NEVER came with 3.55s stock.

Repeat you have 3.27s, you are pushing the same rpms that my stick 96 gt had when it had the stock 3.27s in there. Most autos that I know of in the sn95 usually had the 2.73s so I guess you are lucky in that aspect :shrug:

Did I mention you have 3.27s? :)

Im sure they do, I said the sn95's didnt. By sn95 im refering to the 94-98 body style, correct me if im wrong ive just always called them that after someone corrected me once :nice:

I think the Mach 1's have 3.55s as well. Anyhow, youre right and im right so carry on :flag:

Hello!!! Stick...Auto...Stick....Auto....it's like comaring apples and oranges buddy. :rlaugh:

http://www.tchracing.com/tech/gearcalc.php

3.27 245/45-17's 4R70W (wide 2.84) 2,396.8 @ 80 in 4th
3.55 245/45-17's 4R70W (wide 2.84) 2,602.1 @ 80 in 4th
3.73 245/45-17's 4R70W (wide 2.84) 2,734.0 @ 80 in 4th
 
Ok, thanks for pointing that out... wasnt aware of that, no need to laugh tho.

Anyhow, my entire point was that someone said the car came STOCK with 3.55s and thats simply not true, so I was assuming he still had the 3.27s. Oh well, ive been wrong before :shrug:

so i have 3 73's?!?!?!

i always thought maybe the owner before me did some gearage!

btw... what does (wide 2.84) mean?????

really?!?! i didnt know ford made a 3.45 gear from the factory>>> what rpm are u cruisin at 80??? is urs an auto?

Neither did I until I found it in the shop manual for the 98 and verified that the manufacturing sticker in the driver's side door well showed R as the axle code, which the shop manual says is a 3.45. It was driving me crazy because I always assumed I had 3.27, but I did some math after a couple of other posts and found that I didn't have 3.27 or 3.73. My first assumption again was that I had 3.55 but the math wasn't quite right. I double checked against my dyno runs that had revolutions/mile and that calculated out to exactly 3.45 so now I believe it... :nice:

where exactly is this R located at.. can you take a picture of it by chance.. im so pissed that i am unsure of what my gear ratio is! someone give me a firm answer. thanks./
 
Assuming you have 17" rims, you should be around 80 at 2700-2800 RPMs in 3.27s. The RPMs would be a couple hundred higher in 3.73s.

Sorry dude, based on my math, you have 3.27s.

Why does it matter if you're changing them anyway?
