I have a related question. I am finishing up my 53 big bolt with a 235 engine. When I got the truck the battery was grounded to the frame. I can't remember about other grounds. While I was working on it the only connections I had were the positive to the starter and the ground on the frame. Everything seemed to work ok. The truck started and ran. I know there are usually other grounds, so I ran a wire from the motor to the frame also. Question: Is this ok? Should I have done it some other way, or do I need other grounds, for example, to the cab? Thanks Allen
