MSD Advice?

[BigBlockMopar28]

Anyone care to give me a run down on the different msd boxes? I had planned on getting a 6-al for the dart but I happened to see their street fire box w/ a rev limiter for half the price. What's the difference between these? I'll be running a 400 bb with some goodies if that makes a difference.

Functionally, they will work the same. And you'll probably never know a difference. But what you're going to find is that the 6AL versions have more "bang" lol than the streetfires

High RPM, and Racing Applications where more spark is desired, for a hotter, longer, more stable spark would benfit from the 6AL.. a normal street/strip car, you're probably good with the streetfire.

Whichever box you choose make sure it has a rev limiter. Even if you run an automatic.. Trust me from experience, it's cheap insurance.

I run the Digital 6.
