Neil,
I would think so. But it does have a difference in ohms of resistance. We need Steve!

There are a lot of variables here. If the resistance in the primary winding is lower in the Pertronix coil, which I believe it is, you will have more amperage going through your points, and if it's significantly lower, it will cause them to pit faster and they may even weld together over time. You may also exceed the rating of your condensor, causing it to fail. The next question is, "Is the Pertronix intended to run off 12V on the primary winding all the time or at 8V or so, like our stock units?" Just an FYI, the coil is basically a transformer and the points and condensor serve the purpose of generating an AC signal on a DC line, to make the transformer work. Long story short, I would GUESS it would work for a period of time, but the service life of your parts would be reduced. How much so, I can't say. If you're looking for a "hotter" spark, I would recommend finding a coil that accomplishes that with a higher winding ratio, rather that lower resistance in the primary winding. Hope that all makes sense.
