The Compufire and Pertronix units are smaller, fitting inside the
distributor, and do this job very well.  They are better as they use a
magnet (commonly referred to as the Hall-effect).  By replacing the stock
points/condesor with a modern set up such as these you never have to worry
about setting the points or high rpm point float.  They work in all stock
and most custom engine configurations.

Then you don't want to buy a breakerless ignition (the above).

The CDI replaces the coil.  That's it.  They generally give a better spark,
thus giving better fuel burn and lessening the chance of a cylinder misfire.
