Hey Steve;
Sounds like it's finally going to be HEI time!! Good.
I just followed Langdon's very brief wiring diagram, ran a #10 from my stock switch to the new coil. It didn't make much sense to me to leave the #14 that fed the switch in so I also replaced that with a #10. I just went to our corner FLAPS and bought 8' of red #10 wire. Had a lot left over. The whole #10 thing seems to be way overkill to me but whatever.
I like the ping and twist method of setting final timing. Each engine seems to have it's own sweet spot and if it is set just below the ping point on hard acceleration, you'll be getting the best in performance, and economy. Only thing is, turn the dizzy CW (not CCW) to get rid of the ping. I do use a timing light to get it close before I start the final highly scientific fine-tune procedure. Good luck buddy!!
