Hey whats going on guys..Iv noticed when I try to put gas into my car It goes down hella slow almost like its full but its not .Any ideas y?

Check the hose that connects the tank to the filler neck. Sometimes they can collapse and cause a restriction. Have you looked into the filler neck? Someone may have pushed some crap into it. I'm guessing this is on your 73 Nova. If so it should be easy to check because they don't have an unleaded fuel only restriction gate in the neck.
