Davis Unified Ignition offers 5.0 hot forged distributors for a variety of Ford Mustang and F-150 applications from the 1980s and '90s. These replacements deliver reliable performance and show-quality looks! They have the toughness and durability that 5.0 engines demand. Hot forging provides a denser and stronger distributor, compared to cast aluminum and billet models. Each unit is tested for thermal shock and accuracy between 8,000 and 10,000 rpm. Machined using CNC mills and lathes, the distributors are made to exact tolerances. They include a high-dwell Dyna module for increased spark duration, which provides a better burn of the fuel mixture. DUI 5.0 hot forged distributors come with a steel gear installed for compatible roller camshafts. Order the model recommended for your vehicle.

Performance Distributors D.U.I. nylon shims may be necessary to protect the cam and distributor gears from irregular wear--especially if your engine has had the block and heads milled. If that's the case, then the distributor may sit too far down in the motor, which will "bottom out" the distributor on the oil pump. This is a bad situation which puts the gears in a bind and will cause irregular wear and destruction to the teeth of the gears. These high-impact nylon shims are designed to fit between the intake and distributor gasket. Installing a shim with the correct thickness will allow the gears to mesh properly and can prevent costly repairs down the road.

Performance Distributors Dodge Tri-Power ignition systems offer high performance for small block, big block, and Slant-Six Chrysler engines that cannot fit D.U.I. distributors. The first part of this triple threat is the Dyna-Modules. They mount externally to the distributor housing and have more electronic dwell than stock—longer coil saturation, hotter spark. Secondly, the Inferno coil, also mounted externally, allows you to open up your plug gaps for extra fire to burn fuel more completely and provide more power. The combination of high-voltage coil and high-dwell module will impress you with quicker starting, smoother idle, and better performance—up to 7,500 rpm! The final part is calibration. Tri-Power distributors are tuned based on cam duration and lift, compression ratio, fuel octane, and vehicle weight of each of the specific applications available. A super-smooth advance curve eliminates engine-damaging detonation, provides instant throttle response, and produces maximum power throughout your entire rpm range. Choose a winner that has it all. Feel the difference with Dodge Tri-Power ignition systems from Performance Distributors. Select the model for your application needs.

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.
