    Digital E-Curve Pro-Billet Distributors

    The E-Curve Distributor will drop right in your Ford 289/302 and fire up its performance. The E-Curve Distributor features a digital control module that manages the timing curve replacing the centrifugal advance springs and weights. This module lets you select from nearly 100 different advance curves, including a vacuum advance. You can also set an rpm limit that will protect your engine from overrev damage. These distributors are fit with an ignition module so there is no need to run an external ignition box. This combination makes these distributors ideal for restored muscle cars and street rods to keep a stock appearance under the hood. 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.

  • Digitally controlled, stand-alone distributor
  • Adjustable electronic advance with vacuum advance
  • Select up to 100 different curves through two rotary dials
  • High output ignition module for a powerful spark
  • A rev limit to protect your engine from overrev damage
  • Simple three wire connection and you're ready-to-run

  • MSD Ignition 8503 - MSD Ignition Digital E-Curve Pro-Billet Distributor

    The Digital E-Curve Distributor will drop right in your engine and fire up with three simple connections! Not only are there no external controls or boxes to mount and connect, but you can set a timing curve with just the twist of a rotary dial... no more springs or stop bushings to fumble with.

    A new digital module lets you choose from 20 different ''centrifugal'' curves and five vacuum curves--that's 100 combinations! Simply remove the cap to get to the rotary dials and choose 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. These adjustments are possible due to an advanced, digitally-controlled ignition module. The module also produces a hearty jolt of energy to the coil to produce a powerful spark that will fire up your engine's performance. A magnetic pickup is used for reliable and accurate trigger signals throughout the entire RPM range. The E-Curve Distributor is topped with MSD's Rynite molded cap and rotor and is supplied with a heavy-duty gear and matching 3-pin weather-tight wiring harness.
