As I mentioned I suspected the distributor and or module is not working correctly...

Your mentioning dropping the plug gap down to .035 and it runs better, confirms a lack of high voltage for the spark system...

To check the system, drop in a standard HEI distributor setup and retry your test drive...dont be surprised if it fixes the off idle stumble and misfire...
