60 Valiant MSD 12v source
Odd that Holley-MSD is suggesting the MSD's ground be at the battery. Maybe the electronics are sensitive to noise???
Autotronic's instructions for the 6A, 6T and 6C were to ground to the block.
I can tell you that in my experience with the older 6, the MSD heavy red can be connected near the battery or closer to the alternator with no problems.
I bring it up because depending on what changes you've made, with the 1960 wiring arrangement it may be easier to connect the MSD heavy red at the alternator Batt terminal, and the heavy black to the block or head.
