Well this thread is actually helping me out, and I hope it helps others. Based on what people have posted and what I have read I am going to go with an OD trans for now.
I did see where Speed Inc sells everything you need to swap a TH350 or 400 in an Fbody. Looking at that price when it is all said and done, I will have the exact same amount of money (if not more) in that set up vs an OD trans.
Steve, if you want to shoot me a number on your setup I might actually know someone who wants it.
