Gear change -- Need help!

[SnakeEye]

I am looking to change the rear differential gearing on my '04 SRT-10 from the stock 3.07 gears to 3.55's. Anyone know of a competent mechanic that can perform such a service in the Atlanta, GA area? I am willing to travel 100 miles or so if necessary to get the job done right. Thanks.

how much top end would 3:55's kill?

Approximately 9mph loss on the top -- 184mph (5th gear redline) with 3.55's Vs. 191mph with factory 3.07's (5th gear 5400rpm/drag limited). Benefit of the 3.55's is ~20% more thrust to the rear wheels. I can hardly wait 'til mine are installed!
