Got a unit for an o/t car that ran a 6 cylinder engine; are replacement magnet rotors available for changing to 4 or 8 cylinder? Dang thing wasn't cheap but I don't have anything 6 cylinder to use it on.
You can get the information from the Pertronix tech guys....call them. I believe it is a Hall Effect unit.
They should sell just the magnet itself, if that's what you are asking. I bet they are pretty proud of them though.
The Pertronix is triggered by a series of magnets which are placed by there north or south pole relationship. So there's six magnets now for what you have you now need a ring with 8 magnets. While is sounds simple its a bit involved each magnet ring is made to fit the individual lobe area of the distributer. This means the magnet ring used for the 8 cylinder will only fit on the 8 cylinder lobe area. The other issue you run into is there's no standard 8 lobe area in distributers each brand is a different dimension. I doubt there's anything Pertronix can help you with but give them a call to find out.
