MSD 7AL-3 ignitions bring you outstanding performance and a variety of accessories in one package. Every spark delivers 550 V to the coil with 160 mJ of energy. They offer a built-in, three-step rev limiter that provides an rpm limit for burnout, launch, and race rpm. Their multi-step retard provides up to 20 degrees of retard that can be activated in four stages. An rpm-activated switch can activate different circuits, such a shift light or solenoid. You can also retard the timing 25 degrees during cranking, to ease starting on engines with locked-out timing. MSD includes four 0 degree and one 2, 3, and 4 degree retard module.
