289 vs 318 ..... Ford vs Mopar

So the Mr Norm's GSS counts but the Mustang GT350S doesn't? One came RIGHT from the factory with the blower one was dealer installed.
You couldn't order a 289 with a blower on a fairlane, falcon, base mustang. The car's that you mentioned were available in a limited run only, just like the dodge challenger hellcats or the the newer dodge demon.
