DSII ignition module options?
- Thread starter 69stang_250

Just my single experience, but I tried the NAPA version of the DSII box and it failed about 6 months later. Went with the MSD 6a (didn't get the one with the rev limiter) and it was easier to wire and has been rock solid for about 2 years now. Just make sure you get full 12v to the box. I ran the pink wire from the ignition switch to a Bosch relay next to my battery, which triggers a 12 volt fused line to the MSD.
fwiw, I had a MSD 6 box on my Ranchero with a DS1 distributor (electrically the same only I want old-style wires and a small cap).
I have since swapped to a GM HEI module mounted on a huge heat sink, hidden under the cowl-to-fender brace.
Honestly I can't tell a difference - now my engine is stock, but still...cold starts, idling... The ONLY difference was that when my carb's idle circuit was going WAY lean and fouling the #6 plug the MSD would keep firing through all the crap, but otherwise with a proper carb it's fine.
All that said, I still use MSD boxes on my other two old engines, a '71 Buick 455 and a '69 Ch*vy 350.

"… with a proper carb."
which carb? That's swapped out now? to what?
No longer "going way lean"?
The MSD is just so expensive for me…

I just bought a MSD 6LA module and will post some pictures of the install.
Well as long as I wire the 12V and ground wires straight to the battery I shouldn't have an issue with it. I think it will be the easiest install and fit my application very well.
