What's in the Box

Info

The Digital E-Curve Distributor will drop right in your engine, easily connect to the coil and fire up! There are no external controls or boxes to mount and connect, and you can set a timing curve with the twist of a rotary dial! That’s right, no more springs or stop bushings to change. A new digital module lets you select from nearly 100 different advance curves, including a vacuum advance! Simply remove the cap and rotor to access the rotary dials and select a curve to match your application. You can also set an rpm limit that will protect your engine from overrev 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. 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.

  • Digitally controlled stand-alone distributor with adjustable electronic advance.
  • Set a centrifugal advance and vacuum advance curve electronically.
  • High output ignition module produces a powerful spark for improved performance.
  • Simple three wire connection and your ready-to-run
  • Dial-in a rev limit to protect your engine from overrev damage
  • No MSD Ignition Control required
  • Fits SB and BB Chevrolet engines

The MSD e-curve distributor is a small diameter based distributor. It should work fine with the 3 duece set up.

All Chevy MSD distributors now come with a Melanized distributor gear which is necessary for late model engines such as yours with a factory roller camshaft. This distributor and gear will work fine in your engine.

This distributor along with coil 5478223 or 5478207 would work well. A clamp such as 7209126 may also be needed unless you have the stock clamp to re-use. Then you would likely need spark plug wires. For over the valve cover routing wires 54731359 or for under the header routing 54735599.
