3.42 or 3.73?

[Christopherrr]

My auto is a slug...it feels like it atleast...going with motive, but which would you guys prefer for the 4l60e? I don't drive hard at all and cruise 60ish everywhere I go, but I do drive a good bit and my foot do get down into it sometimes. I get the feeling 3.42s but I want it to be aggressive. I know DJ is going to 3.42s from 3.73s...if it affects my engine, MPG, and tranny that much I guess I'll run with 3.42s...but I'd like a second opinion.

Thanks fellez...

My automatic responded well with 3.73s but the gas mileage took a pretty good step back. Much will depend on the mods you have or are planning to have. If you plan on a head and cam package, torque converter, etc. you'll want 3.73s. If you are planning a power adder like turbo, supercharger or nitrous, go with 3.42s. One benefit of 3.42s is that you can get a complete takeout rearend from a stick car and do the swap, leaving your original rear to bolt back in if you aren't happy. Also, the takeout rear will most likely be quieter.

head and cam...yes...so 3.73 it is. Thank Joe!
