Nelson Granger's 10-second HZ Kingswood Sleeper: A Big-Block Holden Build (2026)

Nelson Granger's 1979 Holden HZ Kingswood is a sleeper with a twist. While his other cars are known for their raw power and aggressive performance, this one is a more subtle, understated machine. Personally, I think this is what makes it so fascinating. It's a car that can go toe-to-toe with the big boys, but it does so in a more understated, subtle way. What many people don't realize is that this car is a testament to Granger's versatility and adaptability as a car builder. From his big-block HJ Kingswood to this more understated HZ, Granger has a knack for taking seemingly ordinary cars and turning them into something extraordinary. One thing that immediately stands out is the attention to detail in the build. The car is finished in the original Holden Chamois color, with a few subtle modifications like the pensioner peak over the windscreen and the Torana steering arms. These small touches add character and a sense of history to the car, making it feel more like a time capsule than a modern-day machine. What makes this car particularly interesting is the combination of power and subtlety. Under the hood is a 454ci BluePrint Engines small-block Chev, which is a powerhouse in its own right. But instead of going all-out with a massive exhaust system and loud modifications, Granger has opted for a more understated approach. The car is tuned to make 600hp at the treads on 98-octane fuel, which is more than enough to keep up with most cars on the road. From my perspective, this car is a perfect example of how a car can be both powerful and understated at the same time. It's a car that can take you to the drag strip and win, but it can also be driven on the street without drawing too much attention. This raises a deeper question: what makes a car truly great? Is it the raw power and aggression, or the subtlety and understated elegance? I believe that a car like the HZ Kingswood shows that there is more than one way to skin a cat. A car can be both powerful and subtle, and that's what makes it so fascinating. A detail that I find especially interesting is the choice of tires. The car is equipped with 15-inch steelies with factory hubcaps and Rotalla 205/65R15 tires up front and Mickey Thompson ET Street S/S 235/60R15 tires in the rear. This combination of tires provides a good balance of performance and comfort, making the car suitable for both street and track use. What this really suggests is that Granger has thought carefully about every aspect of the car, from the engine to the tires, to create a well-rounded machine that can do it all. If you take a step back and think about it, it's clear that Granger has a deep understanding of what makes a car great. He knows that a car is more than just an engine and a set of wheels; it's a reflection of the driver's personality and style. This is why his cars are so successful; they are not just machines, but works of art that tell a story. In conclusion, Nelson Granger's 1979 Holden HZ Kingswood is a sleeper with a twist. It's a car that can go toe-to-toe with the big boys, but it does so in a more understated, subtle way. Personally, I think this is what makes it so fascinating. It's a car that shows that there is more than one way to build a great car, and that sometimes the most successful cars are the ones that fly under the radar.
