MSD ignition/tuning
 

My 76 had the MSD ignition installed in it when I bought it. Is there and adjustment to change the rev. limiter. Right now it allow 5500rpm in 1st & 2nd.

If its a 6AL then you have to buy a "Pill" for it. its a plug in module that you have to buy extra. Just find the right rev limit for your car.

Our hst sells them as well as most speed shops.

How do I know if it's a 6AL?

IT should say on the unit somewhere what the model is. The 6AL was by far the most popular MSD unit for the application.

Make sure you choose your redline properly!

Have you converted your points yet? The Pertronix and Crane optical solutions are popular as well.

I'll have to check it out this weekend. PO may have converted the points - all other upgrades were done.
