426 HEMI Engine-Firewall Ground??

[ignition1]

Does anyone know the location? Or if there is even a grounding strap for the 426 HEMI from the engine to the firewall?

I am working on a ‘71 if this makes a difference for the years.

Photos would help if any )

The negative battery cable has 2 connections , the large one to the left cylinder head & the smaller to the rad wall near the battery , nothing at the firewall .

Much appreciated I have the battery cable and core support one, thought I was missing one possibly for the rear.
