No power in my car
 

So I went to move my car and nothing. No power no interiors lights. Checked battery. Battery good. Check ground and it's good. What can potentially stop power from going into car? Starter solenoid?

I once had the tabs on the fuse block break and this would allow the bulkhead to become unplugged.
Might want to take a close look at the firewall side of the fuse block bulkhead and/or individual main power lead.

Like Jeff said. I did a restoration on a friends 67and finished in 2012. In 2017 the car had no power. All new harnesses. I wiggled the firewall side of the fuse block and had power. Took it off and one of the little connectors was bent. Straightened it and runs good. Just something to check.

Power
 

Just found the problem. The negative power cable is very oxidized. I bend it by accident and saw bunch of white and green stuff come out. I just replace the cable bam started up just fine... Weird I spiced the cable all of it is bad
