Hi Sarge,

I have some recent experience with this. I bought a '55 with 6V positive ground in 2013, from the beginning it was always sluggish on starting and this would get worse when the car was warm.

The car had a 4 gauge cable on one battery lead, a 1 gauge on the other, and in general 1 gauge wires to the block, solenoid, and starter.

Last summer I had a complete new set made from 0 gauge welding cable. I cleaned up all the connections and installed these. The result was a 100% improvement, since then the starter turns swiftly even when warm.

I also replaced the ground wire from the block to the firewall with a 0 gauge cable and this resolved some issues with flickering lights on the instrument panel.

I've seen pre-made 0 gauge cable sets available from either Casco or Concours parts.

Good luck,
