Adjustable crank fire pulley to use with MSD ignition for precise timing.

We have found during our dyno testing that precise ignition timing can make a significant difference in horsepower, and going too far can be disastrous. By adjusting timing on the pulley, our product allows more direct and accurate tuning of your ignition timing. With the pickup on a larger radius circle, you will find that the timing light is rock steady - you can change it a half a degree and know that is exactly what you'll get. This pulley is designed to be used with an MSD ignition.
