Ford overdrive tranny's

It's gonna cost you some bucs to add an AOD and do it right so it will last. You may want to stick with the set up you have now.

I went the Lentech route that makes a beefed up AOD to handle the torque of the 390 and comes with an FE bellhousing to mate up to the 390. You are looking at $3k+. If you go the adaptor route, you still need to find an AOD and have it built to handle the torque. That still may cost you $2k+ combined.
