Sniper and Trunk Battery help

Thanks for the input! Lots for me to chew on and think through.

1. I'm feel I am stuck in the one wire alternator boat as the car sat for 20 years before this "resurrection" and I have already shelled out for the alternator.

2. I e-mailed painless performance about the voltage spike on emergency shutdown. If it doesn't do that I guess I screwed that up as well.

3. The main power wires from the Holley harness have been run directly to the battery terminals. There was nothing in the instructions about fusing them which I thought seemed reasonable as it calls for clean power. The disconnect would kill the battery which would kill the Holley system back on Crackedback's diagram.

4. Perhaps I am using wrong terminology. The ford solenoid would be getting constant current from the alternator on one side of the post. Would that kick the solenoid or is it not enough?

I just like that diagram as it appears to me the starter wire would remain cold after intermittent use in starting the engine.

Sheesh -- my son and I are getting great time together putting this thing back together but it ran 11:20's with the old AVS carb on a cast iron intake and now I am thinking WAY too much about things!
