unfortunatley no they wont
a 4ac dizzy is very simple with points and works independantly
a 4age bigport dizzy is electronic but works in a basic way to give the ecu a signal of engine speed and what not.
a 4age smallport dizzy is from my understanding very close to gze Crank angle sensor, with the distributer part built around it.
reason i know this is that when using an aftermarket ecu they reckon (especially for megasquirt) that a smallport dizzy gives out a nicer signal than the bigport one.
i believe small port dizzy has 4 wires as opposed to the big port dizzy having 3 wires.
