Where to bolt ground wire, Chevy V8 305?

Question

When they put a rebuilt V8 305 in my 1989 Chevy truck, they bolted the ground wire to a mounting bracket, not to the block.  Lately the truck has been more and more difficult to start, and I think it is because the bracket is just a bad place for electrical conductivity.  Starter, alternator, and battery are a-ok.

I want to bolt the ground wire directly to the block, and there's a threaded hole nearby.  See photo:

Is the threaded hole in the picture a good place for the ground wire (I would sand it down to shiny metal first)?  If so, what are the dimensions of the proper bolt, or what's it called so I can ask for the right thing at the auto parts store?

Or is the ground wire supposed to be bolted elsewhere?

yes bolt it to the block and from the block put another one to the frame. Im not to sure on the bolt but remove one that's already in place and match it up be sure to make it a grade a it wont rust or break in the block

The alternate location does not appear to be a flat surface. Many times the ground wire is bolted near the starter as that is the highest current drain/load item. The cable may not be long enough to do that however.

remove the forward exhaust manifold bolt from the block, put the bolt thru the ground wire hoop and install it back where it belongs...thats where 99.9% of all are grounded on small blocks or big blocks.

if u wish u can put the ground cable where u have the pic showing, if the cable isn't long enough to make it to the exhaust manifold bolt.
