Excellent idea! But there does need to be 2 other factors considered that I think everyone would also need to know. Total actual costs for each and the difficulty level for the average guy.

My personal opinion is that each system will have areas where they out-perform the other with the overall advantage going to EFI.

But the carb (if properly tuned) will be much less expensive, even after Thumper's magic and much simpler to install.

If/when EFI gets close to tuned carb pricing, I might consider making the switch. But here's the rub; my Thumper tuned Dominator may not be perfect. But the car behaves so well, that it is hard to imagine how much better several thousand dollars worth of EFI could make it.
