I have an MSD 6AL sitting in my shop unused. My current ERA has a separate rev limiter with a dial adjustment for rpm that works with the exisiting electronic ignition unit. That makes for two "black boxes" and it looks ackward and clumsy but works well.

I'm considering dumping both existing boxes and installing the MSD for the "two birds, one stone" simplicity factor. I would NOT expect any performance increase over my current set up. I don't think you would find any noticable improvement either.

If you have "enough" voltage to fire the spark plugs it really doesn't matter if it's electronic or point type ignition or who makes it. If the plugs fire and the mixture burns clean, your done!

In my case the MSD would "look" way better than what I currently have and I would mount the "red box" under the hood for "show and tell" time!

As your not concerned with the "look" of your current setup I would consider purchasing a separate rev limiter "box". Simpler, easy to install and you can hide it if you like. A rev limiter is a GOOD THING!
