Default 2.94 to 4.09 Is350 diff?

So ive read about this a bunch but never seemed to find anyone with real track data?

Did anyone actually run a car at the track or anything with this setup?

Id imagine on the street it would result in a lot of tire spin down low, especially since the 4.09 diff doesnt have a true LSD but i would think at the track, especially on some drag radials or something the car could hook and take advantage of the gearing.

No data, just a lot of fun and switched it out. It was too much. Like I said before, if I had a switch that I could turn the gearing on and off I would. If you are interested in buying one let me know I have one for sale.

Lol

Hard to justify buying something that people almost immediately remove from their cars.

You didn't like it either darb?
