I think that there have only been a couple or so turbocharged 302 powered Thunderbirds/Cougars. There is not a lot of room to work with in these cars, and will require you to do some custom work. Supercharging is an easier route...and I believe that most supercharged 302s here are using centrifugal blowers i.e. Vortech/Paxton/etc....
