Thanks for the tips guys, as I will be using all the info I can get, as I want to do it right the first go round. I know the AOD (when built right)from Ford can handle lots of power, but did not know someone made an adapter for it to go behind the Hemi. I knew there was one for the 500-618 trannies as well as the 4L80, bbut not the AOD. I am glad to know that, as I have a friend that runs a Mustang performance shop and he has a few AOD's laying around from people swapping over to a C4. So that maybe the way to go for me. Do you know who makes the adapter for the AOD to Hemi? Thanks again.
