running the MSD 6-Hemi ?

If you're referring to the MSD I'd say yes. It's really pretty easy to hook up and tune, just three sensors (don't even need MAP if you don't want, so potentially 2), the coil packs, power, and ground. Plus you get the added bonus of a two step limiter and nitrous retard if you want to use them. I ended up swapping over from my initial carb install back to aftermarket fuel injection, but from what I've heard it can be difficult to set up ignition on some of the aftermarket stuff because you have to have ignitors for the coils. The MSD is a nice solution for that, though I do have to tune with two different programs and it's harder to tune fuel and spark at the same time. Honestly I haven't really touched the spark though since I got the injection back in, just put in the base map from MSD and it's been running good.

The one gripe I have with the MSD is that the wiring harness is really too long if you install the box under the hood. I have mine on the passenger fender and have a loop of the harness tied up that's probably about an extra two feet long. It's a really nice harness that's well labeled and has nice braided cover though.
