How about fuel economy?

 

[joshheat25]

During Acceleration Some one stated that the mpg should not decrease much if at all but when cruising at high speeds around 2-4 mpg. I am definitely thinking about getting the 3.73's now because of the highway miles I run. I need to get in a stang with either one of the gears!! but I would like to know what is the difference in the 1/4 mile from stock to 3.73's and stock to 4.10's

I don't think you'll get 100% answer on that. Mainly because it varies sooo much from car to car and driver to driver.

I am an automatic driver and still recommend the 4.10s. The RPM difference between 3.73s and 4.10 is negligable. If it were a debate between 3.73 and 4.30s...I could understand.

FRPP Gears: $180
Install kit: $50
Having the correct tools and installing them myself: $0
Total Cost: $230

No whine/vibration so far with 1K miles on them. My pinion depth was correct with the FRPP's, however, backlash was off and required one shim change to correct it.

what kind of tools do u need?

Everyone in the Modular Depot is talking about 4.10's or 4.30's for a N/A car! and Not even mentioning the 3.73's for them??

 

[joshheat25]

So 4.10's take off approx .5 seconds in an auto

 

[joshheat25]

How Much time do 4.10's take off the 1/4 mile with an auto I would really like to know, and also what other mods has everyone with an auto done to thier drivetrain with the installation of 4.10's?
