MSD 7330 MSD 7AL

For racers that want adjustments at their fingertips, the 7AL-3 is the right choice. The 7AL-3 packs high voltage with four step retards, three rev limits and an rpm switch. All of the features are adjusted using plug-in modules including the 3-Step Rev Control and Multi-Step Retard. The Rev Control gives you the ability to set one rev limit for the burnout, another for the staging rpm limit ...
