MSD Ignition 7AL-3 Ignition Control
Features a host of the most popular drag racing accessories. A built-in Three Step Rev Control provides three different rpm limits that can be used for the burnout, holeshot and top end overrev protection. There is also a Multi-Step Retard with four different modules that can be activated at different times. Four 0° modules and a 2°, 3° and 4° module are supplied. Many race engines with crank trigger systems or locked-out distributors will benefit from the 7AL-3's built-in adjustable Start Retard will retard the timing 25° allowing the engine to turn over easier. When the engine starts, the timing will automatically go back to its mechanical setting. One last option is an RPM Activated Switch that allows you to activate a solenoid or shift light at an adjustable rpm. When the engine hits the desired rpm the RAS circuit provides a ground to the component to activate it. Vibration mounts, wires and detailed instructions are supplied.
