I know it's not traditional. Maybe this will be deleted. That's OK. But if you have a six cylinder that you want a very good ignition for this is it. Set records at Muroc, El Mirage and Bonneville in 99 and 2000. Went 231 in F/FS one way. Spark was still good. Rod, not so much. Needs a trigger wheel which is about $70 on the bay. They are asking $1300 + for the new unit, Manual available online. Lots of places to connect other things that I don't know what they do. I just wanted spark and I got it. V4GMR@yahoo.com.
