Davis Unified Ignition Ford Duraspark Distributors

Davis Unified Ignition Ford Duraspark distributors are high performance units for those who want a completely stock appearing or factory-style electronic distributor. They are custom-calibrated on a distributor machine and blueprinted to provide maximum power, torque, and instant throttle response. DUI tunes the centrifugal advance using information about the vehicle and engine such as cam duration and lift, carburetor size, compression ratio, vehicle weight, and fuel octane. A super smooth advance curve assures excellent performance and mileage. The vacuum advance is calibrated for maximum fuel economy and light throttle ping is eliminated. The weak factory center bushing is replaced with a full-length bronze oil-impregnated bushing to provide increased durability and cure top-end timing fluctuation, a common problem in these distributors. Davis Unified Ignition Ford Duraspark distributors can be used for everything from everyday street use to all-out racing. They are capable of up to 10,000 rpm with a DUI Dyna-Module and Inferno Coil kit (with other modules and coils, rpm ability is not guaranteed). They come with a brass terminal cap and rotor in your choice of cap colors. Show Less
