    Classic Tech
    On my 68 I have a stock 8in with 3.00 ratio, my plans are to put the edelbrock pro flo EFI 2 on it. I'm not sure if I should rebuild the 8in and put 3.80 in it, because I do have a complete ford 9in that I was given for free. I've heard so much about people putting the 9in on muscles, even...

    2005-2010 V6 Mustang Tech
    I finally got my Vortech installed - not difficult at all! Now I'm looking at the axle - with the increased hp there's just not enough traction, so I plan to get a GT axle. I found a new takeoff dealer with decent prices. Question is, what gear set do I go for? They have all options, 3.31...
  7. Calling All Gear Heads: "Deep" Differential Question

    2011 - 2014 V6 Mustang Tech
    Regarding "deep" gears in the rear differential: has anyone out there (V6, V8, 4-banger, Ford, Chevy, etc., but especially the 2011 V6 'Stang) ever installed rear differential gears so deep as to render 1st gear virtually useless? Did this produce the desired effect of launching harder and...

    Hi guys, I have a 1966 coupe with a stock 289 v8 and c4 transmission. I wanted to swap out the stock gears in the rear end (I believe they're 3.00:1) so that I have a faster acceleration. I was looking at some sets and saw a 3.25:1 and a 3.55:1 ratio set. Any thoughts???

  13. 1988 Mustang GT rear end

    5.0L Talk
    Hi 5.0 lovers! I am wondering if anyone knows the rear end gear ratio for a stock 1988 GT? I found a deal on an 8.8 that I am thinking of putting in my Turbo Stang, but the guy selling it said that gear ratio was 2.73, when I am pretty sure it is supposed to be 3.73. 2.73 would be great for...

  17. What's the stock rear end gearing in a 96 GT 5 speed?

    4.6L Tech
    I've read that they came with 2.73's, but when I jack the car up and rotate the rear tires, I'm getting somewhere around 3.3 revolutions of the driveshaft per wheel rotation. Did the 96 5 speed come with 3.27's, or 3.3 somethings, or has a previous owner done a gear swap? I've searched for...
