Thought I should update this.

A friend had an old arc welder cable that he gave me. I stripped an end and the copper was in perfect shape. I cut to fit and I soldered new ends on it. Shrink wrapped the ends. I attached it to the battery cable where it bolted to the frame, and the ran it up to the bell housing bolt near the starter.

For the record when I got under the car it did have a 1" flat wire going from the engine to frame at the motor mount of the drivers side. I didn't like the idea of that much current flowing through the frame for that distance, so I went ahead an added the heavy copper cable. I didn't want to miss represent that there was no ground, as that could reflect on the previous owner. My mistake.

Prior to the heavy copper ground I installed the voltage meter would pull down to 9 volts with the starter turning and engine hot. Now it only pulls down to a little over 10 volts at the same conditions, so the better ground did help a little.

Thanks for all the tips.
