MSD Digital 6AL-2 Ignition Control, Black

Inside the new cast aluminum housing you'll find an advanced micro-controller that manages the timing and rpm of the ignition. The spark output of the new box has been turned up to 535 volts of primary voltage with spark energy reaching up to 135 millijoules! The multiple sparks of the 6AL-2 burn in the cylinder for 20° of crankshaft rotation to ensure complete combustion.
There are two rev limiters; one for high end overrev protection and another you can activate off a clutch or transbrake to set a launch limit. This feature will help your car blast off the starting line! Adjustments are made via four rotary dials for 100 rpm increment control!
This capacitive discharge ignition will easily connect to nearly any 12 volt negative ground distributor system, even Hall-effect pickups. The ignition is supplied with wiring and vibration mounts for a complete installation. It's even compatible with 4, 6 and 8-cylinder engines.
