DUI are solid as well magnetic triggers,Pertronix are hall effect.
But cross country you still can't beat points and a carb.

Just did a quick look and it seems like Pertronix sells both big and small cap distributors that can be either Hall or magnetic. Not sure why they have both. I haven't found anything on the Pertronix website yet that talks about it. On the Summit site they tell you if it's Hall vs magnetic, Pertronix doesn't even mention it is the specs on their site at all. The DUIs all seem to be magnetic. Original GM HEI were also magnetic, correct?
