Wow, the last digest is a "keeper"!  Posts covered all kinds of background 
about the early improvements to the basic point and coil system. I never put it 
all together- cool.  A couple of other thoughts: In the early 60s GM high 
performance engines that were expected to rev got a dual-point distributor, 
effectively cutting the points opening and closing frequency in half.  I think GM 
didn't mind point bounce in regular cars since it acts as rev-limiter and 99% of 
their production would be protected and didn't need to go there anyway. Note 
that GM made the Turbo Corvairs boost-limit at a relatively low rpm too.  
I recently acquired a distributor machine and I have tested 4-5 Corvair 
distributors.  Most of them begin to suffer from point bounce over 4000 rpm.  The 
one that's currently on the machine starts to bounce above 3500.  Makes me
