Which TBI system is better?

Thanks for the input guys.
It does seem really dumb to put restrictions on making any vehicle run CLEANER than it did originally, which adding injection, and and a cat will undoubtedly do..
In the back of my mind, I know it really makes sense to pull out the BBC and put a earlier Cummins 12v diesel in there and have more twist, more mpg, be done with smog. In the early 90's it was a factory option, and I have photos of the installation so I know it works...
