MSD 6AL Ignition Box with Rev Limiter for use with a Distributor.

Whether you have a powerful street machine, hard working truck or trick street rod, the powerful multiple sparks of the MSD 6AL will ensure complete combustion. Benefits such as quicker ETs, easier starting, reduced plug fouling, more power and even increased fuel economy can be expected with the 6AL's high energy multiple sparks. Like all of the MSD 6 Series Ignitions, the 6AL will work with virtually any vehicle as long as it has a 12-18 volt electrical system.

The Digital 6AL has a microprocessor that monitors and controls every firing and rev limit. All wiring is routed through one end of the unit through a sealed and locking connector. The rev limiter is located on top of the housing for easy access to the two rotary dials to set the limit in 100 rpm increments. The wiring harness, vibration mounts, and components you'll need for installation are included.

Hello, I am interested in your MSD 6AL digital box together with Blaster 2 coil, distributor together with 8.5 mm plug wires. What is price for this kit ? Do you also Elderbrock 850 cfm Carburator with electric choke ? Thanks : ANDY ABASS

Asked by: andyab0001
There is no kit price. And to get a shipping quote and total price, add the item(s) to your shopping cart and then proceed to checkout. In checkout, fill out your address info and scroll down to see shipping options and costs to your area including any import taxes and duties. We do not offer a Edelbrock 850 CFM Carburetor with a Electric Choke. We have several 800 CFM options that have a electric choke. Take a look here:
