LS-Powered HJ Holden Premier: Street Machine Summernats Champion (2026)

Let's talk about a true automotive masterpiece and the incredible journey of its creator, Dave Darcy. This story is a testament to the power of passion and the rewards that come with it.

The Birth of a Street Champion

Dave's journey began with a simple dream - to build a street cruiser, a car that would embody his love for V8s and the classic Holden heritage. Little did he know, this dream would evolve into a trophy-winning machine, taking on the best in the country and leaving a trail of accolades in its wake.

What makes this story fascinating is the contrast between Dave's inexperience and the car's success. Typically, building a champion-worthy car is a long, arduous process, but Dave's first attempt, a 1975 HJ Holden Premier, defied the odds.

A Learning Curve Like No Other

As a novice builder, Dave faced a steep learning curve. He had to master the art of panel beating, painting, and mechanics, all while ensuring the car remained true to its 70s Holden roots. The challenge was immense, but Dave's determination and the guidance of his friend, Adrian Haynes, kept him on track.

The build process was meticulous. Dave stripped the car down, fitted a tubular front end, custom fuel tank, and an LS driveline. He then sent it for professional panel and paint work, where the car's quality took a significant leap forward. The attention to detail extended to painting various components, elevating the build beyond Dave's initial vision.

The Heart of the Machine

Dave's choice of engine was a modest yet reliable 6.0-litre L77 LS. He wanted a car that drove like a daily driver, and this engine, with its factory GM management and a simple cam upgrade, delivered just that. It's a testament to Dave's old-school values and his desire for a car that's both reliable and fun to drive.

Driveability: A Key Focus

One of the standout features of Dave's build is its focus on driveability. The tubular frontend incorporates rack-and-pinion steering, and the wider front wheels enhance the driving experience. Dave wanted a car that fought back, a car that demanded respect and provided an engaging driving experience. This is a rare approach in the world of show cars, where aesthetics often take precedence.

Show Success and Street Credibility

Dave's HJ Premier debuted at Street Machine Summernats 36, and it was an instant hit. The car's unique blend of classic looks and modern performance caught the eye of the judges, and it went on to win the Street Champion award at Summernats 38. But this wasn't a one-off success. The car has amassed a long list of trophies, proving its worth in various shows and events.

What's particularly satisfying for Dave is the Street Champion award's focus on driving. This category rewards cars that are not just showpieces but also capable, street-registered vehicles. Dave's HJ fits this bill perfectly, as it's a true streeter, used regularly by Dave and his family.

Future Plans

With the Summernats Street Champion gong under his belt, Dave is already looking ahead. He's considering turbocharging the car and refining the engine bay, but for now, he's content with enjoying the car and attending various events.

In conclusion, Dave Darcy's HJ Holden Premier is a shining example of what can be achieved with passion, hard work, and a bit of guidance. It's a car that defies expectations and proves that sometimes, first attempts can be truly exceptional. Personally, I think this story is a reminder that in the world of automotive craftsmanship, anything is possible.
