Trunk mounted battery and grounding

[paradigm]

The car has an LS swap and trunk mounted battery. Prior owner used 0 gauge battery and grounding cables from the trunk to all the way to the engine bay. Ground cable runs from battery negative in the trunk all the way to the engine block. Ground seems too long to me.

Where are you guys grounding your engine block to?

Where are you grounding your trunk mounted battery to?

I have a buddy with a '55 Chevy, trunk mounted battery. He relied on the body and frame for the ground. What a nightmare. We added a dedicated ground cable from battery to engine block. We also added three ground straps from the engine ground connection to the frame and body. I forget what gauge cable we used but it was very thick, like welding cables. No more problems after that.
