Auto transfercase ?

[Action]

Just wondering what is the best way to get low with an auto trans? What kind of options are there? Kind of looking for the best bang for the buck. I saw a lot of nice set-ups at pops BD party but not many autos. I would like to be 302 auto,488,36"-37" but unsure where I want to go with the transfer case.Doubler sounds cool but are there options for an auto?
Thanks for any help.

A 3.15:1 Tera Dana 20 set will help the situation, but not nearly like a stak or atlas. A Klune-V can fit in between the C4 and 20 I think which would work fine. Look at the Cold duck if you can fine a used one. A 203 will fit with a WH adapter set for about 1000 bucks plus the cost of the 203 range box. Really these are the only things you can do with an auto C4 drive train to gear it lower unless I am missing something.
