According to wiki, the Lesabre has a 2.86 final drive but mine has a 3.05. According to fueleconomy.gov, our cars get the same mileage. I wonder how much of a difference it would make to swap the 3.05 for the 2.86. Has anyone done a final drive swap before? Notice any improvements?

Apparently there's never been one made for a front wheel drive 3.8L. I read on a forum that its possible to build one but its a PITA and really expensive. If you want a standard so bad, sell it an buy one. I'm planning on doing that very soon...
