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.
