MSD Ignition Distributor, Digital E-Curve

That's right, no more springs or stop bushings to change. A new digital module lets you select from nearly 100 different advance curves, including a vacuum advance. Simply remove the cap and rotor to access the rotary dials and select a curve to match your application. You can also set an rpm limit that will protect your engine from overrev damage caused by a missed shift or driveline failure. This limit is adjustable from 5,000-10,000 rpm.
