I found out that �78-�80 292 chevy�s used a HEI distributor, that are reasonably priced and should fit. They have three wires, red,yellow,black coming out from the distributor and going into a two prong plug. Do you know what these wires should be hooked to. Also would this be a good distributor. Trying to keep the prices down�retired and in my late 70�s
