TBI is a very crude fuel injection method, but it's about 200% better than the best carburetor if the computer is given the right information. As long as it gets adapted to the intake with no vacuum leaks, I don't see any reason it shouldn't work. You'll need to do a LOT of adapting of the sensors, and it's a crapshoot whether the V6 PROM will work with the information from the stovebolt engine. Once the injector is adapted to the engine and supplied with the right pressure fuel, it's all a matter of tweaking the computer.
