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

something has yet to be mentioned. Oil contamination by excess fuel. One of the most beneficial advantages of FI is fuel control, especially in warming up situations. Because fuel is controlled so well in FI, you get engines lasting 300-400K. You get oil changes lasting 5K miles before the oil begins to change color. I remember oil changes on carbed engines being nasty in 3K miles. You change the oil, and 50 or 100 miles later the oil is damn near black again.
