Nock,
As Arte Johnson Would Say: "Veeeeery Interesting!
I used a Pertronics as a trigger for an MSD when I had a Triumph engine
in my black car (Tiny Tim). It did not display any of the oddities that
you describe up to 7500 rpm (where I had the rev limiter set). So I am
wondering if the multiple spark is solving the anomaly or perhaps I just
got a good one.

OK, I've gotta leave the "lurk" mode to wade in on this one...
I wanted to use a Pertronix in the worst way on The Duke of Oil, and I
did.
In the shop it seemed good. No problems without a load on it. First
session out it had a high speed miss! I yanked the dist and put a points
unit back in, no more problems. On the dyno I tried again and it just
wouldn't pull past 5000. Again popped in a modded Lucas unit and saw no
ignition based problems.
Being a very slow learner (or is that stubborn) I spent some time with
the unit on the bench. The first thing I found was that the Petronix
unit was not correctly phased using the supplied installation parts.
After hacking and hewing a different mount, the phasing problem was
solved and it showed a nice spark under any load I could put on it while
on the bench. This seemed to alleviate much of the problem. Once again
the Petronix dist was installed in The Duke. Once again it failed to
perform at high RPM's. Now I really was getting my dander up about this.
There must be some way to make this little bugger work! I sprang for
another new unit as there MUST be something wrong with the unit I had.
After installing the new unit into the Duke I again found it "lacking"
at high RPM's.
At this point, The Duke is back to period correct Lucas and
points...anybody wanna buy a coupla slightly used Petronix units?
Always gettin to the point(s)
