Hey Guys,
I'm thinking about changing the differential ratio in my car and I'm wondering how much difference it would make.
Here are the specs on my car.

351 Ford crate advertised at 362hp at fly wheel
Tremec 5 speed
8.8 axle with 373 gears.

The car is not a racer. I'm just looking for some more 0-60 acceleration.
MPH is not a factor. If it was I'd buy a Prius.

Also, how difficult is it to change rear end gears?
