Actually, it's just the opposite. The problem with a huge cam is that at low rpm's the vacuum signal is low and erratic. In order for a carb to work well, it needs a good vacuum signal. That's why they have trouble idling, ad why you have to be careful about not putting on a carb that's too big.

EFI really doesn't care much about the vacuum signal. It will provide a solid fuel charge regardless of the vacuum signal or intake port velocity. Even with a huge cam and huge ports, the car can idle well and cruise down the street well without any problems at all.

If you have a radical engine in a street car, EFI will make it real easy to live with.
