4.10/4.30/4.56 Acceleration
I am going to change my rear end gears in my 94 gt 5.0 5 speed.
I am trying to achieve the best acceleration. So i am trying to decide on gearing between those 3 choices of rear end gears. What kind of 0-60 and 1/4 mile difference could i expect between these 3 choices. I am aware 4.10s are ussually reccomended around here. But I would like to get an idea of how many tenths of a second i would shave off going to 4.30s or 4.56s.

Everything you ask is totally dependant on your engine combonation and where your engine makes it's power. On a personal note with a a stock 5.0 I like a 3:73. While you give up just a minor amount on your 1/4 mile times (very minor) you gain a lot of freeway cruising.
Chances are a stock 5.0 will be faster in a 1/4 mile run with a 4:10 that the 4:56 Because you can take advantage of the low end torque intead of running out of rpm way to fast between gears.

As others have said, you need to state your goal.
If your goal is the best 1/4 mile time, then it may take some experimenting. In most all cases, the best 1/4 mile gear is the one that takes you over the line just as you are reaching the redline in top gear. Not enough gear will result in going over the line in less than top gear or at an RPM below redline. Too much gear will result in you topping out before you reach the line.
The other consideration is your gear set. The ideal axle ratio and gear set is one that launches well and gives you a set of gears that allows you to stay in the powerband range in each of the gears.
