Do I understand that the main block ground is hooked to a fuel pump bolt?

The ground is connected to a 3/8" stud in one of the factory fuel pump mounting holes on the block. It is a 440 block.

So I'm guessing you have a 1/0, etc from there to the chassis for engine starting?

No, that stud has a 6 gauge stranded copper cable to a common copper ground 3/8"x2"x4" buss bar. The Negative battery cable is also connected to this buss.

I doubt that alternator grounding is the issue.

I do not think it is either, I am just going to take an extra step and ground it's case to the block to be safe.

What if anything are you doing for a batt. disconnect?

I have a disconnect at the battery that kills ALL power to the car when it is pushed in.
