DARYL O’SULLIVAN’S HK KINGSWOOD IS ALREADY A PRO TOURING MASTERPIECE AND IT’S STILL UNDER CONSTRUCTION

STORY IAIN KELLY PHOTOS CHRIS THOROGOOD

CHUCKING fat laps of your local cruise spot is a rite of passage for gearheads all over the world, and it was this experience that led to the creation of Daryl O’Sullivan’s amazing HK Kingswood ute.

LSX-fed two-door commercial has been smoothed and shaved, packing awesome sheet-metal work and engineering like air conditioning, a full chassis and all power accessories under the fresh metal skin. The Kingswood’s new tarmac-hugging, slick finish is thanks to Chris Wells and the team at BMV Engineering Queensland’s Sunshine on Coast, though the story of Daryl’s ute starts many years before.

“I grew up in a country town called Tumut, says Daryl. “Everyone used to cut laps on a Friday night, which is what we did back then, and that street scene is what inspired me. The plan was to have a new car wrapped in an old shell, so when Chris and I planned the HK, it was always going to have all the mod cons like air con, power windows, central locking, power steering, an LS powerplant – and it was also going to be manual.

WHEELS: Daryl chose big hoops for the HK in the shape of Intro V-Rods spanning 19x8.5 up front and 20x12 out back, wrapped in Pirelli 255/30 on the turning end and Continental 325/25 on the burning end

LIVING THE DREAM: “When was young always knew would have an HK ute one day, but not to this extent – it was never meant to go this far,” Daryl says. “I still can’ get over how good it came out”

The HK is actually the first car Daryl ever carried the keys to, though it was a long courtship before he was able to call it his own. “I bought it when was 15 from Wagga Wagga, NSW, he says. “The former owner ran a petrol station near my house and I used to drive past it on the highway for six or seven years, and I’d say: ‘That’s a nice ute. One day it had a ‘for sale’ sign on it, so we pulled in, had a look, and put a deposit on it! It was my daily driver ’til I bought another car. While most utes bought from country areas of Australia are more knocked-about than a Syrian taxi, Daryl reckons his HK was a pretty good thing. “It wasn’t in that bad condition, he says. “It was sky blue with a 186 and everything seemed to be there. My cousin sold me a 192ci six out of his HR, which I put in, but once I bought a daily driver ute, put the HK in the shed and started planning the build.

After languishing in country NSW for a few trips around the calendar, the ute was brought up to Daryl’s new home in Mackay, Queensland, where he finally started building it into the HK of his dreams. It didn’t all go to plan, however.

“The first two shops I went to were a waste of time and money, so I was ready to put it back in the shed and forget about it when came across BMV Engineering on Facebook, says Daryl. “I gave Chris a call to have a chat about it and he was keen to take it on. Over the next few weeks it was put on a truck and sent on its way to BMV, where Chris and the boys came up with a plan and then got stuck into it.

I HAD A VE MALOO WITH A HARROP SUPERCHARGER ON IT, AND IT USED TO GO LIKE A CUT SNAKE. THAT DEFINITELY INFLUENCED MY CHOICE TO GO LS

While it looks like a nicely restored, though slammed, first-generation Kingswood, plenty of BMV’s metal magic has been cleverly hidden. The sills have been extended through the bottom of the front guards, the tailgate has been welded up with a full-width wagon rear bumper bar recessed into the body, the cowl vents have been filled and a full sheet-metal floor added. Custom narrow chassis rails have been fitted that extend through to the Y-frame, which has also been welded to the body. The engine bay is smoothed off, a custom fuel tank and filler are packed under a door in the tray floor beside custom wheel tubs, and the door quarterglass has been removed.

ENGINE BAY: “It is just an LSX376, but with LSX454 rocker covers on it,” laughs Daryl. “The HK was meant to have a stroked L98, but the engine builder wasn’ up to scratch so went with an LSX crate motor. With the brake booster and air con under the dash it was going to be too tight to put the coil packs under there too, so Chris came up with the idea of the engine bay covers to hide them”

“I wanted all the modern stuff wrapped in an old shell, as we didn’t want to take away from the HK’s style – just tweak it a bit to make it stand out from all the rest, Daryl explains.

The AccuAir air suspension works with a custom front end, while the old horse-and-cart leaf springs were turfed in favour of a triangulated four-link. “The front end was an off-the-shelf unit, but Chris ended up modifying it to suit air suspension, Daryl says. “The four-link is a McDonald Brothers unit that has been tweaked to fit the new narrower rear chassis rails, which now run all the way to the front and tie to the Y-frame.

That strength is definitely needed, as the old red sixes the ute had previously sported are long gone, in favour of a 620hp LSX376 crate motor that should have no problems roasting those 20x12 Intro V-Rod rear wheels!

“I had a VE Maloo with a Harrop supercharger on it, and it used to go like a cut snake, so that definitely influenced my choice to go LS, Daryl explains. “They’re cheap engines and they make easy power. This engine made 550rwhp on the dyno, and you couldn’t get an engine built to make that sort of power for what I paid for the brandnew crate motor.

BELOW: HK utes came with short split bumpers mounted on each rear corner, but ABADHK now sports a full-length bumper off a wagon that has been shaved smooth and tucked in tight. BMV also welded the tailgate shut for an extra-smooth look

BENEATH: This doesn’ look like any stock HK Kingswood undercarriage, with a modified Southern Chassis Works front end holding up the LSX V8. A Holley Retro-fit sump clears the front-mounted rack and crossmember, while the custom exhaust is a work of art

REAR END: The diff is a Strange Engineering 9in with 35-spline full-floater axles and a 3.7:1 final drive. This ratio will give snappy performance with the heavy-duty Tremec T56 Magnum six-speed manual, which has been paired to a twin-plate clutch from Direct Clutch. “I’ ve always had manual cars,” Daryl says. “I’ ve never been much on the auto gearboxes as feel you’ a bit more in touch with the car with a manual”

Though it is hard to spot the epic custom twoinch headers that look like tossed spaghetti, you’d have to be harder of sight than Ray Charles to miss the epic Harrop Hurricane individual-throttlebody intake manifold up top. Despite the LSX’s healthy power output, Daryl is already considering pulling the new motor apart to take advantage of the lungs the ITBs lend the 6.2-litre.

“Once it goes off to get painted we’ll pull the motor and do the heads and cam, and get it breathing a bit more to make use of the intake manifold, he says. “It’s at North Coast Custom Trim right now and he’s done the console and trimmed the VE GTS seats, so it’s ready for the billet dash and gauges, then everything is done bar paint. I’m looking at Mazda Soul Red, which will work with a black interior and billet highlights to tie it all together.

We reckon Daryl should take it for a fat lap of good Tumut a once servo he’s ute done can be! to show s everyone just how good a servo ute can be!
