MSD – GM HEI DIGITAL IGNITION MODULES
These digital ignition modules for GM’s HEI distributors generate 7.5 amps of energy, which is hotter than any other module they offer. They also feature an innovative rev limiter that you can adjust externally (up to 9000 RPM) and the power won’t taper off at high RPM because of its advanced dwell control. From ignitions to distributors, starters to coils, from spark plugs to plug wires, there’s an MSD product to help you get the most out of your engine.
