probably not more than .2 - .3. most say it isn't worth it to make this change unless you go to a 3.73 and torque converter. Changing the torque converter with your 3.15's would probably give you more than the 3.42 gear change. Someone with more experience may have better info.

what if i also got a vigalanti 3200, how much better and how is drivability
I don´t think I would gain much with a higher stall.

The 3.42's alone are worth 1 or 2 tenths. Add in a roughly 3000 stall convertor to the mix and your lookin at 5 to 7 tenths provided traction is not a problem! :cheers: :chevy

The local speed shop here told me vigalanti 3200-342-shift kit and a set of slicks and ill lose 1sec or more. Sounds about right reading other forums, what does everyone think. :steering:
