What I´m thinking about... I´be a 3:73 gears on a 318 aproximatly 450hp.. I don´t have that torque so.. changing 3:73 to 4:10 will have a great effect on my ET ?

Have simulated it on software Drag2003 and can´t see much improvement...

You'll see a difference specially with a 318. Since
you basicly dont have much torque you need the steeper
gear to use it as a torque multiplier, you'll be
spending more time at the slower speeds
