Stay with 4:10 gears or drop down to 3:73 or lower
 

I currently have 4:10's and i will be supercharging my car. Not sure if i should get longer gears to let the supercharger boost come into play longer and better for highway pulls.

I think most of the people with blown cars only use about 3.73 gears, don't need more than that because of all the torque they make.....

You running an auto or manual? Autos, especially 4 speeds, tend to have higher (numerically lower) gear ratios which is why they came with 3.08 or 3.27 rear ends as opposed to the 2.73 manuals came with.

I'll second the 3.73 choice. My buddy had 4.56 gears on his turbo'd 600hp car. Needless to say, he had no traction. Ever.

yea and i was possibly thinking 3:55 so i can have a longer power band for highway speeds but do you think the gearing would kill my 1/4 mile times opposed to have 4:10's
