    Rebuild your GM HEI with MSD performance.

    The Ultimate HEI kit has everything you need to make your early model GM HEI Distributor a great performance distributor. The MSD HEI Module features special circuitry that produces 50% higher coil drive currents than a stock module resulting in higher spark energy at racing RPM. By matching the Coil specifications with the module, MSD also delivers more accurate timing and dwell control. To ensure all of this new power makes it to the plugs, the kit is supplied with a high quaility rotor and a durable cap with brass terminals for superior conductivity. Even a new dust cover to top it all off is supplied. Don't mess around with stock appearing ignition modules and cheap overseas models. The MSD Ultimate HEI Kit delivers proven performance.

    Rated 5 out of 5 by from Wish I would have had long ago! I have only driven the car a few times since installing. It is in a 79 Trans Am with a 403. I have owned the car for 16 years and it has never started so quick or run so smooth. I was apparently suffering from a weak spark without even knowing it.
