    Yes, you can add a resistor. Don't know what load the ignition will handle but the coil in your link's primary resistance is only .44 ohms. I would add a 1 ohm resistor and see how it works. My Pertronix, for instance, requires a 1.5 ohm coil. NAPA or some place will have them.

    Could I use a 0.8ohm resistor?

    I found a set of two at radioshack for 3$, i just had to crimp on some spade connectors i had laying around. the msd one at the parts store was about 8$+shipping because they would have had to order it....too much for such a small item in my opinion......must be because its msd lol
