Some builds are big. Some are bad. And then there are monsters like this, a fully engineered, 850 horsepower street animal built to dominate. Tuff Streeters is proud to unveil our latest heavyweight: a 1974 HQ Holden Sedan GTS Tribute that redefines the term “tough streeter.”
Finished in an eye popping Cyan Blue with classic white GTS stripes, this HQ is no sleeper. From the moment you clock the stance and hear the rumble, it’s game over. The body is clean and straight, with the right muscle-era attitude, while inside, it keeps things classic with a brand-new black GTS interior featuring houndstooth inserts — a nod to the heritage, but all fresh under your fingertips.
But it’s what’s under the bonnet that will blow your hair back…
Sitting proud in the shaved engine bay is a 620ci Big Block Chev based on a World block, topped with Pro Topline heads and a hydraulic roller setup. This beast runs on straight pump fuel and still belts out 850HP and 850ft/lb of torque. It’s fed by a carby, keeping it raw and reliable.
Backing the donk is a brand new BTE built Powerglide rated to 1200hp, equipped with a transbrake and 4500 Dominator converter, exactly the kind of setup you want if you’re planning to hook hard and launch with authority.
This is no show pony, it’s fully engineered with the heavy gear to match. Underneath is a Ford 9″ diff with large bearings, 3.5 gears, a TrueTrac centre, and 35 spline billet axles. It’s mini tubbed, rail notched, and reinforced to put all that torque to the ground.
To bring it back to earth, it’s running Wilwood brakes up front, HQ drums in the rear, and adjustable trailing arms to fine-tune the suspension for the street or the strip.
The car will come with your choice of wheel and tyre combo:
- Satin Centerlines — 15×5.5 (Front), 15×10 (Rear)
- Polished Weld Magnums — 17×4.5 (Front), 15×10 (Rear)
- Black Weld Full Throttle (Single Beadlock) — 17×4.5 (Front), 15×10 (Rear)
- Black Weld V Series (Full Black, Single Beadlock) — 17×4.5 (Front), 15×10 (Rear)
Wrapped in either 28×12 Mickey Thompsons or 295/55 radials, depending on your style and setup.
This HQ isn’t just about power. It’s ready to rock on Aussie streets, legally. With 850hp on pump, full engineering, a fresh interior, and bulletproof driveline, this is a $170,000 build that delivers drag strip performance with street rego attitude.
Whether you’re cruising or lining up on the start line, this HQ GTS Tribute is ready to steal the spotlight.
