If you're going to go to all the trouble to adapt an OD transmission to a stovebolt engine, RUN- - - -don't walk away from the 700R4. The 4L60 is the same mechanically as the 700, but it's got electronic shift controls instead of a TV cable. You can buy a stand-alone computer to control the shifting, and avoid all the hair-pulling nightmares of trying to get the length of travel and rate of movement of the TV cable correct. Of course, a much better option would be to adapt a Ford AOD to the stovebolt engine instead of anything GM has to offer.
