Sound advice.
Ballard's F15 suffered similarly; first I had him remove several layers of No.2 Brown from pertinent chassis points and then made a set of truly massive starter and ground cables with 18mm core cable.

No problems since with 6V supply.

There is a lose/lose situation, with the small but significant voltage drops owing to poor connections and often undersized leads, the starter will try to make up for the lost volts by increasing its already huge current drain. This just makes the volt drops worse and during cranking you'll be lucky to see much over 4.5V at the battery. A volt lost in the combined effects of supply and ground connections is not impossible and 3.5V at the starter just wont do it.
