Our Street/Strip Chevrolet DUI Distributor is now available for the popular GM high performance crate engines! This new DUI (Davis Unified Ignition) is designed for the ZZ4, ZZ383, ZZ454, ZZ502 and ZZ6. A special timing curve and a melonized gear sets this distributor apart from our standard Street/Strip DUI. The advance weight and spring assembly is tuned to provide optimal performance for these crate engines. The optimized curve provides instant throttle response and maximum performance throughout the RPM range without any pre-detonation. The melonized gear is installed for proper meshing with the roller cam. Our 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 ZZ 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. If you are looking for a high performance ignition with the simplicity of a one wire hookup, then install our ZZ crate engine DUI and start Driving Under the Influence of more horsepower and more torque!
**Each DUI Distributor is hand built to order with quality components and attention to detail. Due to our meticulous process, distributors are not available for immediate shipping and take time to produce. With added supply disruptions in raw materials, our current processing time averages 6-8 weeks from the time an order is received until it ships.**
*Not Legal For Sale or Use on Any Pollution-Controlled Vehicle in California.
GM Crate Engine DUI Distributors have a one year warranty from date of purchase.
