MSD - 8394 - Set the timing curve with a twist of a rotary dial!

These adjustments are possible due to an advanced digitally-controlled ignition module. Not only does the module offer these adjustable options, it also produces a hearty jolt of energy to the coil to produce a powerful spark to fire up your engine's performance. Also, a magnetic pick-up is used for reliable and accurate trigger signals throughout the entire rpm range of your engine. The 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.
