On this episode of Aussie Garage, we feature Adam’s legendary HQ Holden GTS Coupe, better known as Tuff 383 – a true showcase of Australian muscle car engineering and street presence.
Adam purchased this HQ Holden Coupe around 18 years ago, when it was still a factory grey car running a 383 Stroker V8 engine. After a few years of cruising, Adam decided to give it a full transformation, turning it into the beast that now commands attention everywhere it goes.
The Tuff 383 Rebuild
This rebuild took Adam’s Holden HQ GTS Coupe to the next level. Every detail was carefully chosen to blend street style with raw performance:
- Convo Pro wheels paired with a lowered stance
- Complete rewire and interior restoration
- Sleek panel and paint in BMW silver with ghosted racing stripes
- Engine overhaul by C&R Motorsport Developments
What’s Under the Hood?
At the heart of Tuff 383 lies serious muscle. This is no ordinary Holden build – it’s packed with high-performance gear to deliver power and reliability:
- No 15 Weld heads
- Flat top pistons
- Skat crank & rods
- Holley 930 carburetor
- Edelbrock 2925 high-rise manifold
- 4-bolt mains
- Turbo 400 transmission with hi-stall
- Custom shortened 9-inch diff
Originally a Tangerine 253 GTS, Adam had no hesitation in pushing beyond factory specs. The result is a HQ Holden GTS Coupe that not only gleams in the sun but also roars like a true Aussie street machine.
Why Tuff 383 Stands Out
For Adam, it wasn’t just about looks – it was about creating a classic Holden muscle car with the perfect balance of style and performance. With the help of friends and countless hours of dedication, Tuff 383 now stands as one of the cleanest and toughest HQ Holden GTS Coupes cruising Australian streets today.
As Adam puts it best: “I like to have a bit of power under foot.”
