if long tail shaft 350 in there(should be), then 700r4 bolts in with cross member moving back. Only have to wire in lock up and get correct adapter for tv cable hook up

Does the 350C vacuum circuit not work for the 700R4?

A 700R4 has no vacuum modulator. Its sole source of engine load is the TV cable. You have to have one, and get it properly adjusted.
