you will loose some top end, you will get out of the hole faster. because it is a higher gear your rpms at crusing will be hight and you wont get as good of gas mileage.

our cars do well with 3.73's IMO if its automatic, if its a stick i would go with the 4.11

i think you would like the 4.11 for a while, but with bad fuel economy and burning up your tires more easily i would save and get the 3.73, will give you a faster launch with the auto.

You will only be about 200 rpm higher at a givin speed, gas mpg will not be that much different, maybe 1-2 mpg depending on how you drive. As for you top speed, come on when do you ever do that? In therory you might lose a couple of mph.

too true about top end, you don't really need it and probably shouldn't because i don't think their are too many if any people on here that could tune a suspension on a hot rod like this to handle safely at the speeds this car is capable of, although it is a neat performance aspect that this car can do 160 and i must admit is pretty sweet feeling to go that quick

but yeah i would stay with the 3.73 as that seems to be a better gearing option, i've seen alot of track guys use 3.73

It depends on your tranny. If its an auto try to find 3.73 gears there good from the start to the end and ok on gas. But if it is a 6 speed keep the 4.11 gears.

top end = power in upper RPMs
top speed = actual top speed of the car

you will not loose top end, it will lower it so it will alow you to reach power quicker, and you will have a little bit lower top speed
