RestoCreations It's more important to have good clean battery cables and connections to battery and frame. IMO if
the battery is in the trunk 2 different locations for ground cables in the trunk. For the motor a min of 2 grounds, one one each side of the motor, have them bolted to a dry holes in the head or block. It also doesn't hurt to add one to the trans or bell housing.
the battery in under the hood again 2 grounds min. Major ground wire to the block, and secondary cable to the frame. Also run 1 ground strap between frame and block. Apply dye electric grease on connections to weather proof.
If you are running an FI system, add 1 10 gauge wire for the ecm grounds direct from battery. Rick Lake
