The MSD 7AL-3 Ignition Control has been a favorite of sportsman racers as well as racers that run multi-stage nitrous systems. The ignition combines high output spark energy for high compression race engines combined with the most popular drag racing accessories including a 3-Step rev limiter, 4-stage retards, a start retard and RPM Activated Switch. For 2013, MSD is relaunching the 7AL-3 with upgraded features, a new look and updated internal components including surface mount circuitry. The new ignition, PN 7330, is easy to spot with a black anodized housing and features a new adjustable start retard circuit.
