Best and fastest place to look for the information would be a build location to determine the options, maybe even the Dodge website/build it yourself option.

There may have been an option for a 3.06/3.07 ratio. That's hardly enough difference to make the swap worthwhile.
There may be a 3.9 ratio in the 2.7 cars, maybe that's the other ratio you've heard about.
