Maybe this will help. Wesley explained to me that the NHRA rule book is written in a positive manner. In other words, you can’t do it unless it says you can do it. You can’t run an automatic in a stick only original combination that is in the guide because the rule book doesn’t say you can do it.

You are looking for a nuanced reason to be able to run one because you cannot find a direct reference as to it being illegal. There are some references as to prohibited items such as aluminum driveshafts unless originally equipped.

I think it would help you understand the rule book better if you read it in the manner it was written.
