My 69 RS has a pretty strong 350 that struggles to turn over and start after the engine has been brought to operating temperature. Timing is set at 12 degrees initial, 34 total, and I'm sure it's fighting the ignition system. Car has a nearly new 1000 amp battery, stock high-torque starter, etc.
The battery cables are 4 guage, and I'd like to upgrade them to something larger in order to get more power to the starter, and try to maintain a stock look. Any recommendations?
