DUI-12720-AE427RD - Davis Unified GM 427 HEI Performance Distributor with Red Cap
The Street/Strip Chevrolet DUI Distributor is now available for the popular Chevrolet Performance ZZ427 series crate engine! This new DUI (Davis Unified Ignition) is designed for the ZZ427 . A special timing curve and a melonized gear sets this distributor apart from our standard DUI. 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 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 this DUI and start Driving Under the Influence of more horsepower and more torque!
