3.42 or 3.73?

[Will]

I have complete intake, exhaust, and some ignition and now its time to get these 3.08's off. I am going to get lsd and either 3.42 or 3.73 as my next mod. I dont know which one to get. I have an automatic and i do probably 60% of my driving on the highway. Someone posted a whiole back that it was proven that our cars are faster with 3.42 instead of 3.73. Which one should i get? Wouldnt the rpm at 70 be pretty high with 3.73? 2500+?

3.42's, Thats what I have and I love them. Now with the ability to tune it properly you could go up to a 3.73 gear but, I wouldn't. It can make up to a 5 mpg loss from 3.42 to 3.73's(driver dependent). That comes to almost 80 miles less per tank, So you decide. Both are great gears.

the fastest NA cars on this site used 3.73s.

If you are making a car primarily for the drag strip then 3.73's or 4.10's.

If you want a good daily driver gear and a good gear for the strip then go 3.42's.
