I thought of going to EFI ,but I saw no reason to do it. Efi does have some advantages in that you can map the fuel and ignition curves more precisly. But itīs possible with carbs and a adjustable ignition module to. As long as the engine gets the right A/F ratio there is no advantage in EFI powerwise. To know what A/F ratio you have,you will need a lambda cell, also a EGT sensor would be nice. This goes for both Efi and carb setups. During the dial in period I will use a lambda cell and EGT sensors in all 4 exhaust pipes and the collector, on the new system. Also, blow through carbs could prove more "forgiving" to the design of the plenum etc than a EFI would be. If you get sligtly more flow through some carbs the injectors on a EFI system will still spray the same amount of fuel, on a carb system it will drag the fuel needed. Also if you run a high hp EFI system you will need 8 injectors on a 4 cylinder engine ,otherwise you could get trouble with idle as the injectors would be qite big. Carbs gives better fuel atomizing at low engine speeds. But a EFI setup looks cooler though....
