gear is your friend...go deep. you wont regret it. Ive seen guys go 355 and 373 and hated it...it almost felt the same...
and the reason 10sec cars probably use them is because they have to keep things in range at the finish line.
On a street car that you want the get up and go get some 3:73 at the least in a 5 speed. In a auto youll need 4:10s to get that ass planting feel
