3.55's instead of 3.73's?

I clearly don't have a Gt but when I installed my 3:73 gears in my 11 v6 it totally transformed the car into something different. Mine is a lightly modded V6 and several months ago I test drove a 2013 5.0 with auto which had standard 3:15 gears. I swear my V6 felt faster than that 5.0 . I would think that if the 3:73 gears transformed my little sixer, than can't imagine what it would do to a 5.0. I would go with the 3:73 gears and don't look back.

In my 4.6 standard trans, I have the 3:55s. In a 420HP Mustang I would stick with this rear gearing. That kind of torque in a 3:73 IMO is too hard to manage.

Well, the man has a point about the torque. With 390 lbs torque it may be too hard to manage. My 11 v6 model is no where near the 5.0 level on torque and mine is way more manageable. Mine shoots hard off line with almost no traction issues and I'm on factory stock 17 inch tires.

3.73's are a waste for the street primarily used as a Daily Driver.
Let's look at this another way, let's compare a 2010 4.6 GT w/3.73's to a 2011 5.0 GT w/3.73's, both with a 27.2" tall tire:
2010 GT = 315hp @ 6000, 325tq @ 4500, redline = 6250
2011 GT = 412hp @ 6500, 390tq @ 4250, redline = 6800
2010 4.6 GT w/3.73's vs a 2011 5.0 GT w/3.73's:
1st = 40 mph vs 40 mph (equal)
2nd = 68 mph vs 60 mph (-8)
3rd = 102 mph vs 87 mph (-15)
4th = 135 mph vs 111 mph (-24)
5th = 147 mph (MT82 only)
Top gear @ 70mph = 2000 rpm vs 2100 rpm (+100 rpms)
Should be obvious why it feels like it feels like you shift more with an MT82 5.0.
As you can see, things start going bad for the MT82 5.0 in 2nd gear with 3.73's, as the internal gearing of the MT82 gives you 5 non-overdrive gears compared to 4 non-overdrive gears of all other transmissions.
Without a traction improvement, it is NEVER been better to throw more gearing at more horsepower and torque, which is why all the factory high horsepower cars have long 1st gears.
More extreme, a 2010 4.6 GT w/4.30's vs 3.73's in the 2011 5.0 with 3.73's:
1st = 34 mph vs 40 mph (+6)
2nd = 58 mph vs 60 mph (+2)
3rd = 89 mph vs 87 mph (-2)
4th = 117 mph vs 111 mph (-6)
5th = 147 mph (MT82 only)
Top gear @ 70mph = 2325 rpm vs 2100 rpm (-225 rpms)
How many of the 4.6 GT guys are driving around with 4.30's in their cars?
Interesting comparison of a 2010 GT 4.6 w/3.73's vs a 2011 GT w/3.08's:
1st = 40 mph vs 48 mph (+8)
2nd = 68 mph vs 73 mph (+5)
3rd = 102 mph vs 105 mph (+3)
4th = 135 mph vs 135 mph (equal)

And I totally agree with the more power and more torque with more gear is not always good comment. But add better traction and things change.
I have 3.73's, and I came from a 4th Gen F-body with a T56 that I drove for 13 years. With the steep gearing of the MT82 it's like driving that old Formula with a set of 4.88's. It can be a pain at times but I wouldn't have it any other way.
