Description: Based on the GM HEI distributor, the D.U.I. is a one-piece ignition system with the coil in the distributor cap and the module inside the distributor. The D.U.I. Coil produces 50,000 volts and allows spark plug gaps to be opened up to .050" - .055". The Performance Distributors Dyna-Module has more electronic dwell time in it to give the coil more saturation time to produce a hotter spark. The D.U.I. distributor eliminates the ballast resistor that is used on the stock AMC ignition system to allow full alternator voltage through the ignition system, allowing better spark and more power. Each D.U.I. Distributor is curved on a distributor machine based on the specs of the engine. A super smooth advance curve eliminates potential engine-damaging detonation and gives instant throttle response.


For 71-91 Jeep CJ & Wagoneer SJ with AMC 290, 304, 343, 360, 390, & 401 V8 Engine

Pros: Reliability and performance superior to stock AMC
Cons:

The HEI style distributors replace a weak link on the AMC V8 engines. The original Ford Duraspark system is known for random failure and the points style systems just don't have the power or ease of use.


The clean one wire design eliminates a lot of wiring.
