SHAUN Horton’s wild HQ Monaro just goes to show that a good thing can always be made better. You very likely recognise the Quey’s distinctive, low-slung silhouette from its initial incarnation, CHOPPT, built by Jody Vincitorio. Back then the car ran a 468ci big-block with Crower stack injection, HOK Emerald Green paint and bare-metal and croc-skin cabin that showcased Jody’s flawless metalwork skills.
Under Jody’s stewardship the car featured on the cover of our February 2012 issue and made the Summernats Elite Top 10 twice. It was an exercise in unbridled creativity and never masqueraded as a street car, meaning that it didn’t have to please any engineers or comply with any bastard Australian Design Rules. All it needed to do was be tough as hell and look amazing, two things it did exceptionally well.
As it turns out, Shaun and Jody are good mates, and Shaun kept close tabs on the Monaro’s initial build and developed a real fondness for the car. “I used to call into Jody’s shop on my lunch break at least once a week when he was building the HQ, he explains. “I loved the car, and I always wanted to own something that wild, but never had the time to build it.
Shaun got his chance years later when he heard that Jody was keen to find a new home for the Monaro. Jody had given it a birthday, respraying it orange and blacking out much of the previously polished hardware, including the epic 20x16in Mickey Thompson wheels. Subsequently, he’d yanked the injected big-block and shuffled the Monaro into a darkened corner of the workshop.
Shaun had relocated to Queensland in the years since his visits to Jody’s shop, but having lusted after the car for so long, he wasted little time in strapping his blown, alloy Donovanblocked 400ci Chev to a pallet, shipping it to Shepparton, and flying down to buy the car and resurrect it in Jody’s barn, before dragging it home.
While the extensive fab work and wild body modifications on the car remain largely unchanged from the initial build (see sidebar, p. 35), repowering and re-plumbing it and getting it back into show-worthy condition was a massive job, and one that Shaun and his helpers managed to accomplish in an 18-day thrash.
“We ran all new brake lines and braided fuel lines, installed a new flat timber floor and smoothed, painted and fitted new seats, and made a custom shifter, Shaun says. “The car never had any back brakes, so we fitted those, and resprayed the front of the car while it was there.
Everything was done to an exacting standard; there were 300 hours involved in deburring and polishing the block and heads alone! “We started with a die grinder, then filed, sandpapered and polished it, Shaun explains. “We did it while it was assembled with all the orifices taped up – it was a mission! Even underneath it where you don’t see it’s polished. We linished 5mm off the edge of the timing cover so it sat flush with the block. We had the skin off our fingers by the time we were done sanding in all the little grooves.
The engine itself is a serious piece of hardware, based on a Donovan alloy block topped with AFR 245 alloy heads. Built by Sandy Graham, it runs a .750in solid-roller camshaft, JE slugs, a Scat double-keyway crankshaft and Oliver rods. With a billet TBS 6/71 blower supplying boost and an Enderle Bird injector hat distributing methanol, the combo is worth around 1200hp – enough to turn the steamroller-like 31x18.5x20 Mickey Thompson hoops with relative ease. “It’s virtually a drag car motor in a show car, says Shaun.
A big focus of the overhaul Shaun orchestrated was making the car more usable, fitting things like rear brakes, an alternator and a more practical interior. He and Paul Musty from Shepparton Motor Trimmers worked late nights for a week to install a flat timber floor in the car, and trim and fit-out the cabin. Plastic drag car seats were painstakingly smoothed, then painted in candy two-pack and fitted up. Billet Specialties interior door handles and steering wheel were used, and an alloy spacer was fitted to the base of the steering column to tidy that area up further.
Adding more complexity to the process, Shaun was keen to return the polished finish to all the hardware that had been blacked out. That meant the wheels, radiator, fuel tank and other components all had to be removed, stripped, rubbed and polished. “The etch primer had eaten into the alloy in spots, so that took bulk hours, he says. “It’s a big job when you’re going to show it and it needs to be perfect. Every bolt on the car is button-head stainless and has been polished. It might have been a painstaking process, but one that proved worthwhile when the Monaro returned to the winner’s circle at Summernats this year, picking up Top Super Street as well as a High Impact Award and a Top 20 spot in the Elite Hall. Shaun also had a crack at Grand Champion, making it into the Magnificent Seven and proving that as wild as the car is, it could be competitive in driving events.

With the Quey complete, Shaun is set to knuckle down on an FB sedan build he has on the go. He has serious form in this department, with a blown small-block FB wagon of his having graced the cover of Street Machine back in the day. “I’m doing the chassis at the moment, he says. “It’ll have full rails from front to rear, an adjustable four-link and airbags. It’s a full rotisserie build with flat floors; a show car that can be driven on the street. Every car I’ve had has had at least 1000hp and been blown alcohol. This one I want the same power, but all under the bonnet. The idea have at the moment is for a NASCAR-style motor with the cubes pumped up and more compression – a high-revving naturally aspirated Sounds like combo.
Sounds like something we might be interested in!
