414CI SMALL-BLOCK CHEV-POWERED HQ MONARO TUFHQ – VIDEO

CRAIG Dixon bought his HQ Monaro, dubbed TUFHQ, 12 years ago, and quickly fashioned it into a drag car and Powercruiser that ran a best of 11.0@126mph thanks to a tough 383 Chev. “But I couldn’t really just get in and drive it,” he explains. “I wanted to be able to enjoy it with the family, be more of a cruiser.”

Starting at the front, a flat firewall was added, the wiper motor and brake master cylinder were relocated inside the cabin, and the heater box was shaved, before the firewall and the rest of the engine bay was smoothed off. Out the back, there are mini-tubs and a 40mm wheelarch stretch to swallow the 22x11in rollers.

Its parts list reads like a go-fast honour roll: Arias pistons, Scat crank, Manley rods, Holley carb, MSD ignition, Chevrolet Performance intake and Edelbrock Victor Jr alloy heads.

Danny Makdessi then laid on the custom mix of House Of Kolor Organic Green (with green Metajuls) over a Planet Green base. Those GTS-inspired stripes are also Organic Green but over a lighter green base, giving them a subtle, understated presence.

The dash, door trims, hoodlining and full-length centre console were all fabricated from scratch.
