Your gunna want to run an ignition box also like the one I posted above. They are real simple to install. With as much compression as you have a Multiple spark at low RPM's should do it good.
Well crap. I thought the whole idea behind that pertronix unit was that you didn't need an ignition box because it provides multiple spark and has the rev limiter built in. I'm going to have to call them then and get the scoop.
