HI-6 Multi-Spark CD Ignition Box

The Crane Cams HI-6 Multi-Spark CD Ignition (part number 6000-6440) is a digital ignition box engineered to provide higher spark-gap current compared to standard digital CD ignitions. This unit is fully encapsulated with urethane for operation in severe environments and features an adjustable RPM range from 600 to 9900 RPM. It is compatible with points, magnetic, and module ignition systems. The black housing contributes to its durability and performance. The HI-6 ignition system is suitable for both street and racing applications. It offers features such as a rev limiter and timing retard capabilities, enhancing engine control and performance. The output voltage ranges from 450-480V, ensuring a strong spark. While the product is described as universal fitment, specific installation instructions and potential compatibility nuances with certain distributor types, such as early GM HEI applications or Duraspark distributors, should be reviewed prior to installation. It is often used in conjunction with specific coils like the Crane PS92N or LX92.
