Description

DUI-31820-LSBK - Davis Unified GM LS Conversion HEI Performance Distributor with Black Cap

This DUI HEI distributor is calibrated with very specific advanced curve for the GM LS engine and is for use with timing cover conversion kit listed below.

The advance weights and springs are tuned specifically for this crate engine. The optimized curve provides instant throttle response and maximum performance all through the RPM range without any pre-detonation. The melonized gear is installed for proper meshing with the roller cam. DUI's 7000 RPM Street/Strip Coil and high dwell Dyna-Module are included for the hottest spark output available. No add-on spark box is necessary as our coil and module will fire a massive .055" plug gap! The large gap provides a more complete burn of the fuel mixture for increased horsepower and torque. Vacuum advance is installed for improved fuel economy and cleaner spark plugs. The ZZ4 crate engine DUI is hand built to exact tolerances. Each unit is polished and lubed so that all mechanical parts perform super smooth. Every distributor is test fired to insure all parts are working properly before leaving our facility.

• Simple 1 Wire Hook-Up
• 50,000 Volt Coil
• Dyna-Module allows for massive .055 spark plug gap
