I've yet to hear anything good about Gear Vendors. If you want overdrive then go to a 700-R4, or if you can find the F-body donor, a T56. www.crossmembers.com makes a bolt in dual exhaust crossmember, and just check your local metro yellow pages for a shop that can cut & balance your driveshaft.

The gear vendors deal may be good to 1k hp, but with a motor putting out that kind of power I'm guessing the mpg increase with overdrive would be very little. You might go from 6 mpg to 8 mpg :lol:
