Paul... I do not recall Msd calling their 6AL2 a capacitive discharge system.
 I believe it is a simple multispark system. I called the factory and asked
what was the difference between the 6AL and the 7AL2 and was told after MUCH
HEMMING AND HAWWING that the 7AL2 was a true capacitive discharge sysetem
that also multisparked. If that is true that is a world of difference.  I do
not recall MSD advertising the 6AL to be C.D. system. BTW the hottest
ignition I ever saw for automobiles was the sydmur FIREBALL which put out
100,000 V at the plug. It would fire anything. It is no lomger made because
the mfgr. could not obtain matching transistors cheaply enough anymore. To
get info out of MSD is a feat!!!! JIM DANA

Wow. You are right Jim. I just read the ads in Summit catalog and nowhere
do they mention CD. Summit does not list the 7ALxx in the July Aug 2000
catalog. 

There I go again assuming. Just because it was multiple spark I assumed 
it was CD with a short spark  and  needed to fire repeatedly. 

In order to fire rapidly repeatedly you need to get the pulse voltage up 
due to the high inductance of the coil primary. Perhaps they just use a 300 volt 
DC supply. One could say a 300 volt DC supply has capacitors to store
the charge :-)
