MSD 64253 - BLACK, 6AL, Digital Ignition W/REV Control - Includes Box, Coil and Bracket header-back-exhaust 4 V8 1968 - 1971Overview: The MSD 6AL Ignition Control set the standards that other ignitions strive to reach. In fact, you'll find ignitions from other companies that carry the 6AL name (and in some cases, the same part number). MSD raised the bar even higher with the revised Digital 6AL Ignition Control! The wiring of the Digital 6AL is routed out one end of the unit through a sealed and locking connector. This eases installation and keeps your wiring looking neat
