The Lean Burn (and prior electronics dizzys) have a VR sensor (which gives an AC waveform) and the Ford and Mopar EFI systems (V8, at least) use a Hall Effect sensor which gives a square-wave output.

The Lean Burn dizzy doesn't really help for a Ford retrofit, but it is advantageous for an aftermarket EFI system that merely needs an ignition trigger with locked advance.
