At first glance this 1973 Holden Kingswood HQ looks like a classic Aussie cruiser but then you notice something that stops you in your tracks.

Twin carbs and polished hardware rising through the bonnet.
One look and it makes you think this thing is not messing around.

Nicknamed The Silver Bullet, this HQ hides a seriously wild drivetrain built with no shortcuts and top-tier components throughout. The entire combination was professionally assembled with huge money invested, and it has travelled less than 4,000 km since completion, with receipts to prove the build.

The Heart of the Beast

Under the bonnet sits a 436ci Dart small-block built by Marsh Motorsport a brutal stroker combination designed to deliver massive horsepower and relentless torque.

Sitting proudly above it all is a Chuck Nuyttenbuilt chrome VPW tunnel ram topped with twin 850 Holley carburetors the hardware you can see punching through the bonnet that gives the car its unmistakable presence.

On the dyno this engine produced 670 horsepower on a single-plane manifold and single carb and now with the twin 850 tunnel ram setup, the power potential is even more serious.
