Streetspark/DC ignition?

If it is a dual point design, it means it has twice as many failure points [ pardon the pun ] of a single point dist......& will never be good as an electronically triggered dist....
With todays technology that may be true, (though with so much being made in China these days I have my doubts) but in the 70's electronic ignitions were reviled by many in the same way EFI is reviled by many today... It's easy to not trust the new fangled whiz bang stuff.. "Give me my Holley/Carter carb & my dual point distributors..."

The DC units had a lot of nice features, they have ball bearings supporting the shaft, they use ordinally Mopar points... These are regular dual points, not Duo-coil or Duo-spark... the points are staggered to allow more dwell without excessive point gap... Big point gaps lead to point bounce..
