Engine ground strap 69 Dart

The battery (engine block) to body ground is an area that can stand some improvement. Look at the pass side front of the head. Those bolt holes are on the rear of the driver's side head. Get a Ford style starter cable (eyelet to eyelet) bolt to the rear of the driver side head with a short bolt, and then bolt to the firewall, either a through hole with star locks or on a master cyl. mounting stud.
