Battery cables -where does the negative go?

Quick Question:

On a 66 Barracuda with a V-8, where was the factory negative cable bolted to?

Yes, I realize the "Battery" LOL! Where does the "OTHER" side get bolted to - a picture would be great.
Thank you,
Joe
Joe, I have a few pics of small blocks. I have seen heads where the boss wasn't drilled and tapped like yours. Most heads have the cable connected there. One was connected to the corner intake bolt and one was connected to the outside exhaust manifold bolt. That's where mine is connected. (whether it's the original location or not)engine 296.jpg
