MSD’s heat digital HEI module and performance coil will fire up your stock HEI distributor. The module is a direct plug-in for the 4-pin HEI module and will produce up to 7.5 Ampere of current. This increased energy will continue through racing RPM reaching 9000 RPM! The HEI module is extremely accurate in its delivery of this energy resulting in more accurate ignition timing. Another unique feature is an adjustable rev limiter. You can dial in an engine saving rev limit ranging from 5000 to 10000 RPM. To get the most performance out of the HEI module, MSD offers a performance coil as well. This coil drops right in place of the original, and fits under the stock cover.
