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.
