I recently changed the 350 Turbo in my 49S10 to a 700R. I have an Edelbrock carb. You need to buy the bracket that bolts on the carb where the accelerator and TV cable hookup. TCI and several others sell them. It changes the arc of the TV cable to be the correct distance. My tranny guy had me set the TV cable by doing the following:
With the throttle cable hooked up and "at rest" pull the TV cable until a resistance is felt, then pull 1/2" more and hookup. It seems to shift fine. I also used a Lokar bracket for the TV cable that bolts to the back of the carb. Good luck.
