DUI-12720-FB385BL - Davis Unified GM Fast Burn 385 HEI Performance Distributor with Blue Cap
This Chevrolet Street/Strip DUI Distributor is now custom tailored for the GM Fast Burn 385 Crate Engine! The DUI (Davis Unified Ignition) is your complete ignition system in one simple unit. Only one 12 volt hot wire hooked up to the DUI delivers 50,000 volts of intense spark energy to the plugs for a cleaner, crisper and more powerful running engine. No add-on spark box is needed! The secret to the DUI's performance is the specially designed centrifugal advance mechanism. This special weight and spring assembly is hand fitted and dialed in using a distributor machine for a precise curve that will match the specifications of the GM Fast Burn 385. The super smooth advance provides instant throttle response and maximum power throughout the rpm range. A vacuum advance is installed for better fuel economy and cleaner spark plugs. A high dwell module and 50,000 volt coil produce the high output spark. Dwell within the module has been increased electronically to allow the coil to produce a longer duration spark. The high voltage coil allows plug gaps to be opened up to .055". More dwell plus a larger gap means you'll get the most complete combustion of the fuel mixture possible for increased horsepower and torque. The fast burn DUI is available with a black, blue, red, yellow or clear distributor cap. A melonized gear is installed for compatibility with the factory camshaft.
