The reference at the beginning of the Super Stock section:

"Reserved for foreign and domestic factory-produced automobiles and sports cars. Classified per NHRA performance rating as listed in the Official NHRA Stock Car Classification Guide. Only those cars listed in the guide are eligible."

The reference at the beginning of the Super Stock GT section:

"Reserved for foreign and domestic factory-production two-door coupes, two-door sedans, sports cars, convertibles, or station wagons with any production V-8 engine of the same make. Year of engine optional. Only those engines and/or bodies listed in the Official NHRA Stock Car Classification Guide are eligible
for competition."

You can view the class guide on NHRAracer.com for the 1970 Ford as an example. The GT section references both manual and automatic transmissions. Look under the 302 column and you will see only HP factors for the manual referenced and none for the automatic for OEM heads or replacement heads.

Which means the manual transmission is the only one in the guide and eligible for competition. There is no factor if you wanted to run an automatic so it wouldn't be eligible.
