I have no doubt I could tune a decent EFI system and would do my homework before buying. I also have no doubt a well tuned carb system can come very close to the performance level of EFI. Seriously, I believe that, I suspect the vast majority of carb systems are not optimally dialed in, that could be said for EFI as well!
In either case, to get them to work at their highest level you really do have to know what your doing.
Why I prefer a carb over EFI is simple, the "wow" factor of dual fours is equal to the "wow" factor of EFI, in my opinion, at a fraction of the cost!
Tom K's comment, as I recall, about EFI was about the same time he was getting ready to run Bonneville with the K car. He wanted to spend the time DRIVING it, not working on it! Tom could certainly work out the bugs, given enough time.
