    MSD 8503 Details

    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 by turning two rotary dials!

    You can also set an rpm limit that will protect your engine from overrev damage caused by a missed shift or driveline failure. These distributors are also fit with a high-output 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 or clean 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.
