    With only (3) simple connections you can install this MSD Digital E-Curve Distributor in your engine and fire it up. There are no external controls or boxes to mount or connect and you can set a timing curve with an easy twist of a rotary dial. The digital module allows your choice of (20) different centrifugal curves and (5) vacuum curves for 100 combinations by simply removing the cap to get to the rotary dials and select a curve to match your application. This distributor has an advanced, digitally-controlled ignition module that allows you to set an RPM limit (adjustable from 5,000-10,000 RPM) to prevent over-rev engine damage and it also produces a jolt of energy to the coil to produce a powerful spark that will increase engine performance. MSD's Rynite molded cap and rotor tops the E-Curve Distributor and is supplied with a heavy-duty gear and matching 3-pin weather-tight wiring harness.

    Features:
  • Easy 3-Wire Connection
  • Built-in Rev Limiter
  • Stand Alone Digitally-Controlled Distributor with Adjustable Electronic Advance
  • (20) Centrifugal Advance & (5) Vacuum Advance Curve Selections
  • High Output Ignition Module Produces a Powerful Spark for Improved Performance
