There are few shapes more iconic in Australian motoring than the 1971 HQ. This GTS captures that timeless silhouette and infuses it with modern engineering and true street attitude.
Finished in sleek Mercedes Silver with classic black GTS stripes, the exterior strikes a perfect balance between factory inspired heritage and aggressive stance. Subtle split rear tubs allow for serious rubber underneath, giving the car a muscular, ready to launch profile
that defines proper Australian muscle.
At its heart sits a Blueprint Engines 454ci Pro Series engine, a package built for reliable, repeatable horsepower. With a 10:1 compression ratio, aluminium cylinder heads, forged pistons and crankshaft, and a roller camshaft, this naturally aspirated combination produces 620 horsepower of thunder.
Fuel delivery and engine management are handled by a Holley Terminator Stealth EFI system paired with a Holley ECU and dedicated wiring integration. The result is the best of both worlds: classic V8 sound and feel, combined with modern drivability, clean throttle response, and consistent tuning.
Supporting hardware has been carefully selected to handle the power. Cooling is managed by a PWR aluminium radiator and Spal thermo fan, ensuring reliability even under demanding conditions.
Behind the engine sits a full manual two speed Powerglide transmission with a 4200rpm stall converter and heavy duty tailshaft, a proven street strip
combination built to handle serious torque.
Out back, a shortened 9 inch rear end with 35 spline axles, a 3.89:1 gear ratio and Truetrac centre ensures the power is put down properly. The wheel and tyre package completes the stance, with 17×4.5 V Series wheels up front and aggressive 15×10 rears wrapped in 275/60/15 tyres. It’s a setup that looks right, and works hard.
Inside, the cabin has been fully refreshed in classic black GTS trim with timeless houndstooth seat inserts. A B&M Stealth shifter reinforces the car’s performance intent, while a Holley 6.86 inch Pro Dash integrates modern digital data seamlessly into the vintage interior.
This HQ GTS is more than a nostalgic build. It’s a carefully engineered, 454 cube powered machine that respects its heritage while delivering modern reliability and serious performance.
Don’t miss out on the chance to make it yours!
