Actually, just for '67's, you can confirm a factory 400 model straight off the body tag on the firewall between the brake master cylinder and the wiper motor.
It should have a code "3F" under options. But the full PHS documents are of course better to have.
I will warn you though - you are missing a couple of the factory telltales for a 400 model from the front end. And your original center console, if the car had one - would have been a matching red.
