Starter does care about polarity.

The ground strap originally ran between the + on the battery and attached to the engine on one of the water pump bolts, I believe.

On some cars, there was a secondary strap between the transmission and the frame.

If you running 6v, make sure all the cables are the thicker 6v variety. Way too many have been replaced with the thinner 12v variety over the years, which creates all kinds of hard starting problems.
