Now there's no need to build your own high-output distributor that you can tune for non-computerized HEI Chevy V8's. The ignition experts at Moroso have done it for you! Moroso's DuraFire Distributors come equipped with everything needed to customize the ignition timing curve for your particular street/strip application. They feature several high-output components including Moroso's ProCoil that provides more complete combustion for easier starts, smoother idle, improved acceleration and more horsepower! The Moroso DuraFire Distributors now feature improved weight and advance cam pin retention by TIG welding the pin backside to prevent them from coming loose and upgraded strength of the plastic wire harness plug so that the two lock tabs do not break off when unplugging the harness from the distributor cap.
