FI Camshaft v. Carb Camshaft

Hey, this is my first post. I desparately need some information. What is the difference between a performance cam for a fuel injected motor and a similar performance cam for a carbureted motor?

The biggest difference is lobe separation and overlap, efi needs minimum 110-114 LS the bigger cams need wider LS, a carbed car can use a cam with narrower LS thus increasing power to a point. You can use a a "carb" type cam if you are using a programmble type efi as you can run it in open loop at idle but if it is a closed loop system then a cam with 112+ LS is required.
