The MSD 8987 is a digitally controlled accessory that allows you to select a 5°, 10°, 15° or 20° of retard while the engine is cranking. The unit pulls the timing back during cranking, so the engine will start easier. Once the engine starts or when the key is released, the timing returns to the set mechanical amount.
The Start and Step also features a single stage of retard making it ideal for nitrous engines. This retard can easily be activated when the nitrous is turned on, or add a switch for a high speed retard. You can simply dial in 1°-15° with the rotary dial for quick adjustments. The Start and Step will easily connect to magnetic pickups and has a points input as well, plus it can work on 4, 6 or 8-cylinder engines.
Features:
- Compatible with 4, 6 or 8-cylinder engines
- Accepts points, amplifiers and mag pickup trigger signals
