This article on Daryl's HK ute was first published in the November 2018 issue of Street Machine
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.
The 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 on Queensland’s Sunshine 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.”
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 I 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, I 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 I 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.”
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 quarter-glass has been removed.
“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 brand-new crate motor.”
Though it is hard to spot the epic custom two-inch 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 Tumut once he’s done to show everyone just how good a servo ute can be!
