Tell me why I should or should not switch to fuel injection!!!!!!!!!!!!!!

FI is just like overdrive. You have to drive it enough to justify the cost. They are more expensive by far than a typical carb, when you factor in all the fuel system mods.
Also, look at the Fitech thread. It goes on for dozens of pages about issues. Also, are you a mechanic, or are you an electronics tech?
And in closing, i have one carb that has never worked right. Most of my carbs have been on my cars for years without any issues. Those guys in the old days with all the carb issues didn't know how to tune them. Not that I'm an expert.
