FAST HEI Conversion Kits have everything you need to upgrade your factory HEI Distributor. For racing and street performance applications, each FAST HEI Kit has a new high-output HEI replacement module with built-in 20° start retard. Each conversion kit also includes a new distributor cap, rotor, coil cover, and matching in-cap Coil. By matching coil specifications to the module, FAST Racing delivers more accurate timing and dwell control for higher spark energy at racing RPM.

The HEI/CD Ignition Conversion Kit allows you to convert the standard HEI module/coil combo to a high-output Digital CD Ignition while retaining the stock-look cap.
