Good advice and understand. Quality cables are a must.

My engine ground to frame is @ 12", and my frame to batt is about the same.

My ALT ground is about 8", which connects to the same point on the engine as the frame ground.

I have a ground that goes from the frame right next to the body mount to the body, both with riv-nuts.

I have one ground from the back of engine to the firewall with a riv-nut.

One more ground goes from the frame to the junction of the inner & outer wheel housing, all riv-nuts.

Also have a core support to frame by the batt, both w riv-nuts. At the core support junction where the ground meets the core, I ran a wire over to the fender. Overkill, but fine by me.

Basically, the entire left frame rail is a ground (on the GTO). The body has those 3 mentioned ground points on the frame. Frame has been blaster and powder coated, another reason for the riv-nuts.

For the passenger compartment, the lower dash rail is the ground for everything in the dash, and from the driver's side lower dash rail mount, it's inches from the body ground-to-frame point.

All but one frame grounds are 6AWG, the ALT-block-frame-batt run is 2AWG (maybe 4AWG, would have to actually check, but pretty sure it's 2AWG).

On the bird, being a unibody, I will run a dedicated ground the length of the car on the driver's side, with 4 mount points along the way using riv-nuts. Will use the dual-cable batt terminals.
