S&S Super Stock ignition systems are available in complete ignition kitsand as replacement modules S&S single fire ignition coils are available separately Keep in mind that the curves are preset for a specific S&S engine, and that modules intended for one engine may not yield optimum results when used on another configuration Generator style engines require reverse timer gears and a special timer, designed to accept an electronic ignition S&S offers two beautiful billet timers for this application
