How good  are the new ignitors? Do they require a special coil?


Well there are three different ignitors as i remember. The first is ignitor 
 I. It requires a coil with a STOCK primary resistance of 1.35 ohms if the  
ballast resistor is in the circuit. So any coil will work if it has that 
res. 
ignitor II is designed to use their coil with a 0.6 ohm pri res. It will  
work with others but is best with their coil. I'm not currently familiar with 
 ignitor III, so others will have to advise you.


Bob,  I'll check my distributor with your procedures too. Just curious if 
the retard  unit works as expected.


You can't check the retard unit that way (via my procedures). It requires  
actual pressure (engine under load) to activate. Also you should know that 
the  Chev specs for the retard units are grossly incorrect. Actual retard 
pretty much  follows boost pressure....meaning max retard at max boost, and min 
at min.
 
let us know if you need more help or information.
