In the build: ProFlo HQ GTS, EH ‘Tonner’, home-brewed ’67 Camaro plus more

We check out some projects in the build from the February 2024 issue of Street Machine


ProFlo Performance
HQ Holden GTS

“This HQ Holden started life as a genuine GTS sedan in the rare hue of Gunmetal Metallic with Lone O’Ranger stripes. Owner Mick isn’t good at keeping anything original, so he quickly got into the build by getting the car sandblasted, and then dropped it off to us here at ProFlo Performance to give it the signature stance we are known for.

“We’ve modified the rear end to fit the 15×10 Weld Racing rear wheels and 275/60 tyres. In order to turn that rubber into smoke and keep Mick pleased, nothing less than 632ci of full-fat Chevy will power the HQ.

“The car is now off getting panelwork, and the original colours will be sprayed back on before heading back to ProFlo to get fitted up and ready to hit the streets by 2025.”

Simon Smith
EH Holden

“This is my EH Holden project in the build, which I call ‘Crazy Dream’. It was supposed to be a five-year build but has taken 12 years so far! When I first got it, it was full of rust, and everyone said I was crazy for taking on such a rust bucket, but they couldn’t see my vision. It now has a full chassis with flat floors, tubs and custom suspension.

“The powertrain is a carburetted LS1 backed with a 4L60E transmission and BorgWarner diff. The EH rolls on custom-built 18×7 and 18×10 Schott wheels. Interior comfort will include a full Rockford Fosgate sound system. I can’t wait to be able to drive it.”

Mark Everingham
1967 Chevrolet Camaro

“I thought I’d share a bit of info and pics of my 20-year ’67 Camaro build. I’ve done pretty much all the work myself, starting in an eight-metre single garage and progressing to a double garage over the years. It’s now had the firewall smoothed and recessed for dizzy clearance, an HZ wiper motor mount added, and the a/c and heater blower holes filled, as the car was optioned with heater-delete. The inner rear wheelwells have been massaged with hammers, and the outers have been de-lipped and repaired.

“I made a buck out of timber and used that to hammer-form the mini-tubs, and I also fabricated the relocated shock mounts and a couple of scallops in the rear beaver panel for the exhaust. I have a Blueprint 383 crate motor to go in it, which ran 436hp and 464lb-ft on the dyno. It will run HPC-coated Hooker headers. Behind that will be a TH350 rebuilt by Warilla Automatics with a Cyclone Transmission Super High Performance kit imported from the US.

The diff is a nine-inch with 31-spline Moser axles and 3.25:1 gearing. An Aussie Desert Cooler radiator, polished alloy overflow, chrome alternator and power steering pump, billet pulleys and brackets, and a Hi-Torque starter are ready to go. That’s just the tip of the iceberg, and there’s plenty of stuff that still needs doing, including the interior, but it’s coming along.”

Eddy Hoek
EH Holden ‘One Tonner’

“One of my current builds is an EH tilt-tray ‘One Tonner’. This car has an HQ Tonner rear chassis and a lightweight aluminium tray. The engine is a 350 Chev, with a Turbo 350 trans backing it. It has a custom four-link rear end with a full-floating, sheet-metal nine-inch diff. The front end is a Castlemaine Rod Shop IFS conversion. It’s currently sitting on my rotisserie after sandblasting so I can cut out the rust and fit new floors.

“The rear tray was cut off and the cab refinished, leaving a section behind the cab to hide the fuel tank. The tray is a super-light aluminium construction that will be finished with aluminium chequerplate and opened with power rams from a remote and concealed button. To complement the diff and rear tyres, I’m looking to fit twin turbos, which will also give it a bit of extra under-bonnet bling and go!”

Josh Cody
Holden HK Kingswood

“Here’s my 1968 HK Kinger. It’s undergoing a full overhaul from a go-to-the-pub skid pig to a trailer-queen show pony. My old man and I slapped it together 10 years ago to get it to Summernats, but it’s now at Handmade Metalcraft, where all the magic is happening.

“It’ll be running an LSA engine and a manualised TH400 with enough power to spin some big tyres. It’ll also have a full custom chassis with a United Speed Shop front end, full Air Ride suspension and heaps more to come. The aim of this car is to try to be Grand Champ at Summernats and win some trophies, so look out for this build!”
