Ground wire relocation
Alright while I was doing my timing chain cover I notice the ground off the battery looked like he'll. I noticed they had it directly on side of block. From the battery. Idk if that's correct maybe, butthe wore is shot as seen in picture. But here's my question. I snapped bolt off at the block. So now what do I do. Where can I ground it?

Yep, looks like a new negative cable is needed, lol
If you can't get the old bolt out, anywhere on the side of the block is OK, but make sure there is a nice flat boss or mounting surface. Chase threads too. Use a star washer. This is the main ground connection point for everything so it has to be good.
Grind boss down to bright shiny metal at the block, past any paint or corrosion, and tighten cable hardware securely. Coat with vaseline or grease like NO-OX. I'd go ahead and also replace the ground strap at the frame too, the short strap going to firewall from engine, just judging by the looks of that one. They all get corroded and start to drop considerable voltage.

if you connect the battery to the frame it is not connected to anything else if the braided strap from block to frame is rotted out.
the engine and cab are rubber isolated to the frame, so there will be no electrical connection.
the battery gets connected to the block because that is where the starter is grounded to, and the starter is the largest current draw.
body is grounded to the block with a smaller braid wire from the back of the head to firewall, and a smaller wire from battery to radiator support.
the frame has a small braided wire also, unless someone removed it or it rotted off.
