1993-1997 LT1 F-Body Ignitions

MSD Ignition Systems produce hot multiple sparks that ensure complete combustion of air / fuel mixture, resulting in increased performance over stock.  

• Quicker throttle response • Smoothed out idle and starting • Reduced Spark plug fouling • Improved Fuel Economy • Helps Reduce Emissions

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.

The MSD 6AL shares the same proven circuitry of the 6A with the addition of a built-in adjustable rev limiter. The combination of powerful sparks with the safety of a Soft Touch Rev Control is what makes the 6AL the most popular ignition control in the world.  MSD first developed the Soft Touch rev control to prevent overrev damage to your motor in the event of a missed shift or driveline failure. The rpm limit is adjustable in 100 rpm increments with MSD’s plug-in modules. When the engine reaches your selected limit, the Soft Touch circuitry begins dropping the spark to various cylinders. On the next cycle, these plugs are fired again to prevent fuel from loading up in the cylinder. The result is a smooth and accurate limiting action without backfires or roughness.

The Soft Touch Rev Control also opens the door for you to add rpm accessories such as a Two Step Rev Control. A Two Step allows you to set two rpm limits, one for a holeshot rpm and another for overrev protection. The 6AL is supplied with rubber shock mounts and modules for 3,000, 6,000, 7,000 and 8,000 rpm.

The MSD 6 BTM is ideal for engines with a turbo or supercharger. Not only will the engine benefit from MSD’s full power CD sparks, but there is also an adjustable boost/timing retard circuit to prevent detonation.  When your supercharger (turbo or blower) forces the air/fuel ratio into the engine, the cylinder pressure inside the combustion chamber increases. The result is a great amount of power but this can also lead to detonation which can result in severe engine damage. The 6 BTM lets you dial away detonation by retarding the timing in relation to the boost pressure. By electronically controlling the ignition timing your engine can run on the threshold of detonation to obtain maximum power and efficiency. The BTM features a dash mounted control knob that lets you adjust the amount of timing retard. It can be adjusted from 0° per pound of boost to 3° per pound. The boost pressure is monitored by a sensor built into the MSD. The 6 BTM also shares the Soft Touch Rev Control of the 6AL Ignition for overrev protection. The BTM is supplied with rubber shock mounts and rpm modules for 3,000, 6,000, 7,000 and 8,000 rpm.

To some, putting a carburetor on a GM Gen III V-8 is a step back in progress, but to many enthusiasts that do not want to run high pressure fuel lines and miles of wiring, this is a giant step in the right direction!
GM Performance Parts and Edelbrock now offer cast aluminum intake manifolds that allow the installation of a carburetor on these advanced small blocks. But, without the EFI’s ECU, they needed a controller to fire the ignition and MSD stepped up to the plate.
This compact ignition controller is fit with matching factory connectors for a direct installation. Only a handful of connections are required; the coils, crank sensor, MAP sensor and the cam sensor. This Controller also allows you to map a timing advance curve with MSD’s easy-to-use Pro-Data+ software. Other features that you can set include a two step rev limiter, a vacuum advance curve for cruising economy and even a step retard in case you want to add a little nitrous to the mix.

Last year, MSD introduced the Gen III LS-1/LS-6 Ignition Controller, PN 17-6010, which was designed for engines being retro-fit with a carbureted intake manifold. This year, their engineers have come up with a wiring harness that allows the Controller to be used with the factory EFI and coil assemblies! The Harness, which connects inline to the factory sensors, allows you to program an ignition timing curve, a step retard for nitrous use and select a two step rev control to help with consistent holeshots. You can even program a boost timing curve if you’ve fit your engine with a supercharger or turbo.

All of these features can easily be programmed via a laptop through our Pro-Data+ software.
