Just a little update, with nothing more than a "technical experience". As I have been driving the 66 as of late, I had noticed the car had become a little more temperamental to start. I had a symptom where when the car was warm, the ignition would only fire when the switch was turned to run (as opposed to firing while cranking in the start position). That symptom increased little by little. Yesterday afternoon, I cold started the car, and the problem persisted. The ground is VERY good on the T.I. amp. Previously, I had checked my voltages as the coil, was well as looking for any resistance on the ground side of the T.I. amp. All were within spec.
I remember a while back, I had read some posts over on Corvette Forum where some of the others had complained about the same symptom, and blamed it on the brand of circuit board I installed in the T.I. amp.
Having nothing else to do today as a result of the weather, I thought I'd dive in. I was being a little lazy, and just reinstalled the original T.I. amp that was in the car when I received it. The car now cold started and hot starts just like it should......while cranking.
Most of the GM cars did not utilize the T.I. ignition as widely as Corvette's. Some of you though, have cars with this buggy whip ignition system. I just thought I'd post the experience for technical reference down the road for Yenko.net.
Enjoy the rest of your weekend. I myself now feel I've earned a cold beer
