83 mustang 5.0 with a 340 hp ford crate motor should I go carb or efi???

Stay with the carb, you'd need a gt40 or equivalent intake, 65mm TB, 75mm mass air, all the sensors, not to mention you'd have to set up a fuel system, computer and a professional tuner to get the same performance as the carb setup you describe. If a carb is tuned properly then you can get decent mileage, I usually get about 15-17mpg city and 22-25mpg highway.


The swap would be worth it if you were going to go with a blower or a turbo but N/A there would be not much point.
