Ignition

| Originally designed with NASCAR in mind, the 6ALN CDI ingnition control box is equipped with the mandatory 6-Pin Weathertight connector to meet NASCARs ignition wiring rule, 20-6.1. Plus, a special clear base plate is also installed for easy tech inspection | The 6ALN has a built-in Rev Control | These rev controls are adjustable with plug-in modules and will save your engine from over-rev damage caused by missed shifts or driveline failure | Multiple spark, capacitive discharge ignition control | Designed for circle track racing with NASCAR mandated connectors and clear epoxy potting compound for vibration protection | Circuit board is encased in a clear two part silicone elastomer | Clear plastic base plate for easy tech inspection |

| Built-in Soft Touch Rev Control is adjustable with RPM Modules | Multiple sparks for 20 degrees of crankshaft rotation | Works on 12 - 18 volt electrical system | Accepts breaker points, amplifier and magnetic pickup trigger inputs | 470 primary voltage output to coil | Programmable for 4, 6, or 8-cylinders by cutting red/blue wire loops |

| Supplied with rubber shock mounts | Supplied with 3,000, 6,000, 7,000 & 8,000 RPM Modules |

| The Soft Touch Rev Control, PN 8728, is designed to be used on standard points ignition or inductive ignition systems. This means that the PN 8728 can be installed on engines with a GM HEI Ignition, Ford or Chrysler electronic ignition, any standard breaker points systems or even with an MSD 5 or Blaster Ignition (non-CD ignitions). The RPM Limiter is adjusted with plug-in modules and is supplied with 6,000, 7,000 and 8,000 rpm modules. When the engine reaches your set rpm, the Soft Touch circuitry kicks in and drops the spark to certain cylinders. This rpm limiter produces very accurate and smooth, backfire-free rev limits |

| Can be used on 4, 6 or 8-cylinder engines with inductive ignitions | Adjusted with plug-in modules | Includes 6,000, 7,000 and 8,000 rpm modules | No MSD ignition control box required |

| In applications such as off-road, marine or other harsh conditions, the MSD Blaster High Vibration Coil is the best choice. The sturdy metal housing of the High Vibration Coil is completely pot­ted with a premium grade epoxy to completely encase the coil’s primary and secondary windings. This protects the coil’s internal components from high and low frequency vibrations that are commonly experienced in racing |

| Metal canister is encased with epoxy to protect the windings from high vibration applications | Improved output coil for electronic ignitions, and MSD Ignitions (ballast resistor required for points) | 100:1 turns ratio and lower primary resistance produce high voltage output |

| If you are looking to upgrade your stock coil, or want to compliment the performance of your MSD ignition, the Blaster Coil line is the right choice. Special 100:1 windings, kept cool in an oil filled metal canister, are used to provide maximum build-up of voltage.  The tower assembly is molded of durable alkyd material due to its high dielectric characteristics while wide spaced brass primary terminals prevent the possibility of spark. Can be used with a stock ignition, Blaster Ignition, or MSD 5, 6 or 7 Ignition Control |

| For use with stock or MSD electronic ignitions. Most late model vehicles with electronic ignitions do not require a ballast resistor, check your ignition and manufacturers specifications to determine if a ballast is required in your application.  Mallory Unilite applications also require the ballast resistor | Improved output coil for stock points or electronic ignitions, Blaster Ignition, or MSD 5, 6, and 7 Series (ballast resistor required for points) | 100:1 turns ratio and lower primary resistance produce high voltage output |

| MSD Red metal canister is filled with a premium grade oil for cooling |

If you have a slightly taller block or have decked the heads, the distance between the distributor mounting pad and the cam gear/oil pump drive may be different. MSD offers these Distributor with an adjustable slip collar with 1.5” of adjustment so you can be sure the distributor is installed correctly. The distributor shares the same features of the standard Pro-Billet Chevrolet model including a ball bearing guide, long sintered lower bushing, oil seal, and an adjustable mechanical advance assembly. The maintenance-free magnetic pick-up in the billet base of the distributor triggers the MSD CD Ignition box (not included). Fits Small Block or Big Block Chevy V8.

You can't go wrong with the best selling MSD Billet Distributor! The housing is machined from a billet of 6061-T6 aluminum on a state-of-the-art CNC machine producing exact tolerances. For high rpm stability, a .500” steel shaft is supported by a sealed ball bearing and a long sintered bushing. This shaft also receives a QPQ coating for friction reduction and resistance to corrosion. A precision machined reluctor is attached to the shaft which triggers the magnetic pick-up mounted in the housing. This high output magnetic pick-up is the most accurate way to trigger your ignition. Plus, with no moving parts to wear or adjust, the pick-up is maintenance free! Just above the pick-up is MSD’s adjustable mechanical advance assembly. Different springs and stop bushings are supplied so you can tune an advance curve to match your application.

This strong, billet aluminum distributor is set up for engines that run locked-out timing or an MSD Timing Computer. With no advance assembly, the rotor plate is welded directly to the oversized shaft. A sealed ball bearing guides the top of the shaft while an extra long sintered bushing stabilizes the lower portion. Trigger signals are produced via a high-output magnetic pick-up. This pickup is extremely accurate and never requires adjustment. Since this distributor is designed primarily for race engines, an oversized (.006”) bronze gear is installed along with an adjustable slip collar for modified blocks, heads or intake manifolds.
