LC LJ LH LX and UC Torana Repair Manual
The Final Evolution of the Torana Line
The Holden Torana LX represented the peak of Torana performance, producing legendary variants like the SS Hatch and the A9X homologation special. By this point, the Torana had evolved into a serious Australian muscle car with strong racing pedigree.
In 1978, Holden introduced the final Torana model, the Holden Torana UC. The UC shifted the focus away from outright performance toward comfort, refinement, emissions compliance, and practicality. This reflected changing market conditions, tightening emissions regulations, and Holden preparing the market for the upcoming Commodore range.
The UC would ultimately become the last Torana ever produced.

Verdict – Which Is Better?
The LX Torana represents the high point of Torana performance and motorsport success, while the UC Torana represents the end of the line and a shift toward refinement and practicality.
For most enthusiasts, the LX will always be the more desirable car thanks to its performance variants and racing pedigree. However, the UC deserves recognition as a comfortable and important final chapter in the Torana story.
The UC closed the book on one of Holden’s most important nameplates, paving the way for the Commodore to take over as Holden’s primary mid-size car. Today, both models remain important pieces of Australian automotive history and symbols of Holden’s golden era.
