I have a quick question. I had been set on 4.10 gears, mostly because its what you guys recommend running an auto transmission. However, ive recently thought about my plans for this car, which includes F/I. Should i stick with 4.10 or go with 3.73. I also saw a gear kit for 4.30. Is this applicable for the best results using auto + F/I. Thanks for anyand all help.

go with at least 4.10 if you have an auto.

Ok, but what would be better 4.10 or 4.30? Isnt it the higher ratio the faster acceleration but lower top speed or am i mistaken.

Are you strictly going to drag race?

i might take it to the track couple times a year, but this wont be a flat out drag car. I was just wondering what would compliment an auto the best, and also an auto + F/I

If it's an all drag car you can get 4.30's. If you plan on it beeing a streetable car, don't go more than 4.10(or less for that matter)on an auto.

there is no reasonable point other than the track to ever worry about lowering the overall top speed of your car (and you'll never hit that speed in the 1/4 mile) Our cars can go a bit faster than our spedometers read...plenty of people on here have pegged 150...

if you're ever in a situation where you're street racing and hitting your top speed, you gotta re-think what you're doing becuase you're going to kill yourself or someone eles doing that....especially in a vert...IMO anyway....

p.s. go 4:10s

the fastest ive taken it is 100 between baker and barstow... at 12 a.m. whats the 4.10's going to do to MPG or engine life with the higher rpm's at any given gear?

You'll probably loose a few mpg's, as far as engine life goes, just keep very up to date on your oil changes and it'll be fine.

Go 4.10's. With an auto, even if you are f/i, it will be fine. IMO the reason most say to get 3.73s if you are going f/i is most are 5 speeds. 5 speed tranny + 4.10s + f/i = Lots of fast shifting.

thank you... i appreciate all the help. i guess a tranny cooler would be in order too. haha
