PerTronix 91581LS Ignitor II Kit For Original 8 Cylinders Single Point Prestolite Marine Distributors, 12-Volt Negative Ground.

.Ignitor Electronic Ignition Conversion Kits have proven themselves in applications ranging from race cars to tractors. It is the number one Electronic Ignition Conversion Kit to replace original mechanical points. A Pertronix Points Conversion kit allows you to run a stock distributor while improving the reliability and performance of your ignition system. The Pertronix Ignitor kits simply bolt to the distributor in place of the points assembly and provides a much more accurate trigger signal. This improves the timing accuracy and prevents ‘points bounce’ at higher rpm. The electronic technology also improves the dwell control to improve the spark output of the coil resulting in a hotter spark at the spark plug. With this dependable, self-contained, maintenance free electronic ignition system you'll never replace your points again.
