The Evolution of Nelson Granger's Automotive Journey
Nelson Granger has a penchant for late-70s Holdens, and his story is a fascinating evolution of automotive passion. From his previous feature in Street Machine with a big-block HJ Kingswood to his latest creation, the HZ Kingswood, Granger showcases a unique approach to car modification.
A Shift in Style
What's intriguing about Granger's HZ Kingswood is the departure from his usual high-powered builds. This car, featured in the April 2026 issue, offers a more subtle yet equally captivating experience. Granger's decision to opt for a 'sleeper' style, a car that looks unassuming but packs a powerful punch, is a refreshing change.
The Build Philosophy
Granger's approach to this build was strategic. He sourced the car in bits, intending to use parts for his HJ. However, the HZ's neat condition led him to embark on a budget-friendly build, a stark contrast to his previous projects. The choice of a BluePrint Engines small-block, while still substantial at 454 cubes, was a conscious decision to improve handling and meet engineering requirements.
Technical Insights
The engine setup is a masterpiece of simplicity. With a BluePrint crate engine, Edelbrock intake, and a healthy dose of nitrous, the HZ achieves an impressive 600hp. The use of a Truetrac centred-Salisbury diff, though unconventional, is a practical choice for budget and handling considerations. This car proves that performance doesn't always require exotic components.
Handling the Beast
Granger's experience with handling large-bodied Holdens shines through in this build. He employs Torana steering arms and castor adjustments to make the HZ more responsive. This attention to detail is often overlooked but is crucial for a balanced driving experience.
Interior Aesthetics
The interior pays homage to the 70s Holden style, with a black retrim preserving the car's original charm. Granger's decision to keep it free from roll cages and flashy modifications highlights his respect for the car's purity. It's a refreshing take in an era of over-the-top customizations.
Performance and Potential
Despite its sleeper status, the HZ has proven its mettle on the drag strip, running low 11s in the ITF Hire 235 Aspirated class. Granger's intention to run a nine-second pass is ambitious but understandable, given the car's potential. The balance of power and reliability makes it a true sleeper, ready to surprise anyone at the lights.
Final Thoughts
Nelson Granger's HZ Kingswood is a testament to his evolving automotive journey. It showcases a different side of his expertise, where subtlety and performance coexist harmoniously. This build challenges the notion that power must come with flashy modifications, proving that sometimes, the most exciting cars are the ones that don't shout about their capabilities.
