Check that out, couldn't I just have that made by my local machine shop for like $200? The actual adapter plate is really simple, but what about the torque converter and flywheel? Would I just have to drill the 391 flywheel and use the 700R4 convertor or how would that work? I really don't want to pay $800 for that kit so if I can't have one made cheaper I will just go with the C6 or maybe even just rebuild my cruise-o-matic sigh....
Thanks for all the help everybody!
