340 has a hard time starting when hot?

Will check, was wondering if the stock cable from the solenoid to the starter is too small for 10.5 comp and 505 cubes . ??
Solenoid is about where the heater motor use to be . Its where the ''free'' no.1 welding cable reached to from the trunk mount battery /on the pass side .

Check the ends on the cable, see if there is any corrosion or broken wires. Also if the cable gets hot while cranking it's too small.

I never thought about my small block cranking until I relocated the battery to the trunk. I ran a O or OO welding cable from the solenoid in the trunk directly to the starter. It cranks and starts better now then ever before. The starter even sounds different.
