MSD Ignition 8504 Digital E-Curve Distributor for Chrysler 318 340 360

The Digital E-Curve Distributor will drop right in your engine, easily connect to the coil and fire up! There are no external controls or boxes to mount and connect, and you can set a timing curve with the twist of a rotary dial!\nThe E-Curve Distributor is topped with MSD's Rynite molded cap and rotor and is supplied with a heavy-duty gear and a matching 3-Pin Weathertight wiring harness.\nThese adjustments are possible due to an advanced digitally-\ncontrolled ignition module. Not only does the module offer these adjustable options, it also produces a hardy jolt of energy to the coil to produce a powerful spark to fire up your engine's performance. Also, a magnetic pickup is used for reliable and accurate trigger signals throughout the entire rpm range of your engine.\nThat'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 over-rev damage caused by a missed shift or driveline failure. This limit is adjustable from 5,000-10,000 rpm.
