I don't think it was ever put into production. Was it?

They tried but it was not a good engine. It's design - to rev to 9000 RPM to take advantage of the huge ports didn't take into account the lack of longevity of the bottom end. Almost all of the Ford Trans Am equipped Mustangs blew their engines long before the end of their races. The 427 Tunnel Port engine was a stouter design but it too went into history very quickly. It was replaced by the 427 SOHC engine.
