Gears & Axles - Bigger gear question

Hello- I currently have 3.73 gears in my 10 bolt, How would increasing to 4.10 gears effect my DDing and highway driving? And 1/4 mile Track performance?

I have a LS3 418 Stroker motor 575 hp/508 trq with Automatic transmission.

Thanks in advance:usa:

I have probably 320 rwhp and I can't put it to use. Can't imagine 575hp. I know it sucks but you're wasting your time with the 10 bolt.

i cant see needing 4.10 gears with that rwhp.......

how tall is your tire?

Why, Can you explain? I don't know much about gearing -thanks

Right now it's a 295/35/18 but I want to change to a 15" wheel w/ a 28" MT DR Tire.

Ideally you want to go through the traps near peak hp rpms. I'd suggest getting the tires first and seeing what mph and rpm you're turning through the traps unless you already know what trap speed you typically run and use this gear calculator http://f-body.org/gears/ to see if the 4.10s will get you through the traps at peak hp rpm. A 28 inch tire needs some gear to work good N/A.
Some people with autos can get the 10 bolt to live into the 11s.

Ok thanks for the 411 :), are 10 bolts that weak? I hear guys saying they've been in 10s with this rear. I added a bearing cap stud kit & TA Axle girdle to add strength.
