Trunk mounted battery and grounding

[64nailhead]

Connect everything to the frame. Don’t need a ground cable all the way to the front. But don’t ground to the body and expect it to transfer to the frame cleanly. Ground the engine to the frame and the body to the frame. My race car ran fine with the battery in the trunk. Cranked a 15:1 565 just fine.

I can't disagree with this as long as the frame is in good condition. I recommend to the block because the block will not have excessive corrosion like a frame may, repat may, have.

But don't add 12 grounds (exaggeration) that include the frame, block and frame. If electronics are being used, then ground loops are a true concern.

Good point about the ground loops, particularly when dealing with late model multiple CPU driven systems. For a fossil application where an HEI constitutes high technology, not so critical but, since we now live in a vacuum where it takes an AI to tell you how to sneeze, having to deal with multiple processors that don't like to talk to each other unless forced by software to do so, making sure they get the message loud and clear has become a high priority.
