Ground straps go where?

I'm not a "resto correct" guy but basically

the main battery cable ('big one') gets grounded to the block. This is where the high current for the starter "goes."

Many other circuits are grounded to the body, so the body must be securely tied to the block and battery. I like to buy a short "starter" (ring to ring or eyelet to eyelet) cable and bolt to the rear holes in the driver side head. Bolt the other end to the firewall. One bolt that you can use is the master cylinder mount studs.

The VR basically must be at battery ground potential. Make sure it's mounted tight, scraped clean around the mounting holes and flange, and star lock washers.

Factory original was minimal and barely adequate
