4.10?

 

[97_gt]

4.10's on a stock motor isnt that a bit much

 

[darkside03gt]

no 4.10s arent too much but it really depends on what direction you want to go with the car. if you plan on staying N/A then go with the 4.10s. if you plan on any kind of FI go with either 3.73s or 4.10s depending on what kind of FI you go with. 3.73s for a twin screw and 4.10s for a centri.

will this hurt my express way driving cuz i do alot of it

It wont hurt anything except it may bring the gas mileage down a few MPG.

If you are going for the headswap later on 3.73's or 3.90's will do just fine. You cant go wrong with either 3 of those gears, but if you do alot of highway id suggest sticking with 3.90's or 3.73's if you really drive over 75-80mph alot.

I have 4.10's and tach 3k RPM at 80mph... we have the same transmission as well, so it should be the same for your car.
