Posted on 11 March 2013 by admin

Download MSD 7AL-3, IGNITION CONTROL PN 7230 Important: Read the Instructions before attempting the installation. Parts Included: 1 – 7AL-3, PN 7230. 1 – Parts Bag (wires and connectors). 4 – RPM Modules 3000, 7000, 8000, 9000. 4 – Retard Modules 2°, 3°, 4°, 4°. 4 – Zero Degree Modules. 4 – Vibration Mounts. WARNING: During installation, disconnect the battery cables. When disconnecting the battery, always remove the Negative cable first and install it last. Note: The MSD 7AL-3 will retard the ignition timing approximately 4° compared to other MSD Ignitions. After installation, the timing should always be checked and adjusted at idle and total timing. Note: This unit is designed for 8-cylinder engines only. COIL RECOMMENDATIONS The MSD 7AL-3 can be used with a variety of coils, but to receive the best performance, it is recommended to use an MSD Coil. For drag racing and “short duration” applications, the Pro Power Coil, PN 8201, is the best choice. For street applications, the MSD Blaster 2, PN 8202, is recommended. The 7AL-3 may be used with a GM HEI Distributor with an internal coil, however the Rotor Bushing must be replaced with an MSD Low Resistance Bushing, PN 8412. MOUNTING The 7AL-3 can be mounted under the hood, but should be mounted in a position away from direct engine heat sources. Use the ignition as a template and mark the location of the mounting holes. Remove the unit and drill the holes using a 1/4″ bit.
