MSD

MSD offers an all new Digital HEI Module and performance coil that 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 amps of current all the way to 9000 rpm! The Digital Module is extremely accurate resulting in more accurate ignition timing. The adjustable rev limiter allows you to dial in an engine saving rev limit from 5,000-10,000 rpm. This digital module can also detect if traction control has been installed. For street cars, you’ll never know this feature is there, but for circle track racers that are breaking the rules, they’ll find themselves with a low rpm limit activated! If a traction control event is detected, the Digital HEI module will go into a rev limit mode. To get the most performance out of the Digital HEI Module, MSD offers a performance Coil as well. This Coil drops right in place of the original coil and fits under the stock coil cover.
