Ground, battery, alternator cables

[hi8ha]

Want to replace the engine to chassis, transmission to chassis, positive/negative battery and alternator/starter power cables.

Planning to make the cables myself using welders cable (more strands and better conduction), would a 2awg suffice?

Already aware of the need to have a very good crimp connection.

What causes the OEM cables to fail is not the gauge or number of wires, but corrosion build up inside the cable and particularly the cable ends, which causes the internal resistance to go up. The replacement OEM cables designed to address this corrosion issue have something injected into them to retard the corrosion development over time. Welding cable is not treated in this manner and would probably do no better than the original cables.

Thanks for the clarification.
