The MSD 6A is the base model of the capacitive discharge multiple spark 6 Series design. Whether you have a powerful street machine, hard working truck or trick street rod, the powerful multiple sparks of the MSD 6A will ensure complete combustion. Benefits such as quicker ET’s, easier starting, reduced plug fouling, more power and even increased fuel economy can be expected with the 6A’s high energy multiple sparks.
Like all of the MSD 6 Series Ignitions, the 6A will work with virtually any vehicle as long as it has a 12-18 volt electrical system. It can be triggered using breaker points, a magnetic pickup or the output of an electronic amplifier. All necessary parts and wiring instructions are included.
I'm interested in the MSD TIMMING RETARDER.... the website supplied only suggests that it can advance timing... I presume you can also retard it for higher boost correct? Do you have the wiring diagrams/manuals/etc.. and all the required parts for this?
