Home-brewed 1974 Ford XB Falcon

Tomi Vatavuk's XB Falcon is an exercise in detailed design and homebrewed engineering, with 433 cubes for motivation

PRACTICALLY everyone on the planet agrees that XA-XC coupes are right up there with the best-looking body shapes ever smashed out of sheet steel. However, there’s a lot less love for the humble more-door version out in the modified car world. Tomi Vatavuk’s stonking sedan bucks that trend, and demands much more than a cursory glance.

Getting a Falcon to sit this low over monster 20x13s takes a huge amount of work! “We didn’t have to touch the wheelarches, but we did move the diff back to centre the wheels in the guards,” says Tomi

Tomi’s family played a significant role in developing his passion for 70s Falcons from a young age: “My brothers are eight and nine years older than me, so I grew up being that annoying kid following them around,” he says. “Tghey always had tough cars. There’s a video of one of my brother’s mates in an XC doing doughnuts in a car park, and I was in the back seat! I must have been about 11 years old.”

The 19s down the front may seem small by comparison, but they still have to clear the bodywork at all suspension positions and provide a home for the 355mm Brembos

It was about the same time that Frank Piccolo’s blown orange XB GT (SM, Jul-Aug ’92) took out the coveted Street Machine Of The Year award, fuelling Tomi’s desire for an XB of his own. In 2001, after years of dreaming and saving, in the end a few hundred bucks and a case of beer landed him this very sedan. “It was a Skyview Blue Falcon 500 with three-on-the-tree,” says Tomi. “The weekend I bought it, me and my mate drove it up to Sydney to go to a Pantera concert!” A ‘vulgar display of power’, if you will!

Tomi drove the XB as it was for the next few years, before he decided it was time to build the car he’d always wanted it to be. “I mounted it to a rotisserie and stripped it – sometimes I’d work on it all night and I wouldn’t sleep at all!” he says. Tomi’s good mate Johnny Musladin (whose own much-modified EH was featured in SM, Jun ’96) stepped up to handle the serious metalwork. Everything between the rear seats and the rear of the boot was cut out and replaced with mini-tubs, drastically raised frame rails and a custom-rolled boot floor.

The XB’s massive feet invite all sorts of comments, ranging from blaring praise, to criticism, to downright head-scratchers. “Some bloke looking at the car at Summernats said: ‘I love it because the wheels aren’t Simmons’!” laughs Tomi

Underneath, the stock diff and leaf springs were turfed in favour of a fabricated nine-inch and triangulated four-link with RideTech coil-overs for handling the bumps. The front of the XB didn’t miss out on the upgrades either, with more RideTech coil-overs controlling RideTech upper and lower arms. The vague steering box and linkage were replaced with a RetroRack billet rack-and-pinion set-up, and a set of Stubtech drop spindles allow the sick ride height while retaining suspension travel and geometry.

Just like everything else underneath the XB, the big stoppers were far from a bolt-on proposition – Tomi and Ross ended up milling their own rotor hats and caliper brackets to mount the DBA discs and FPV Brembos. The brakes are actuated by a standard Ford master cylinder and booster, with vacuum provided by an electric pump hidden in the boot. “I wanted to pay homage to the Falcon GTs of the 70s, but go way beyond them in terms of performance, handling, comfort and finish,” says Tomi.

Tomi’s CAD work is everywhere under the bonnet, though the strut tower covers and the air cleaner are the most obvious examples. The tower covers transitioned from paper to CAD models, then 3D-printed plastic to check the fit, then finally into CNC-machined aluminium

Speaking of comfort, have a Captain Cook at that interior! The trim patterns and shapes were inspired by those of the Ferrari 458 Italia and Lamborghini Huracan. The dash is the standard unit, albeit trimmed in Alcantara and filled with Speedhut gauges, and a great deal of effort went into making a heating system that works well and is hidden from view – Tomi even 3D-printed his own heater vents, plenums and tubes. Cardboard, MDF and modelling foam were used to create models of the door trims and other custom interior parts, from which moulds were made for the carbonfibre end products.

“I couldn’t find an air cleaner that would fit under the bonnet, so I designed one around an off-the-shelf filter element and we milled it from a chunk of aluminium,” Tomi says

Outside the cockpit, that sensational combination of Maserati and Mazda silvers puts a cheeky twist on the classic Falcon GT blackouts. “I think they need the GT stripes to break up the colour, but I thought black would be too much of a contrast,” says Tomi. There isn’t enough room in this mag to list all of the work put into the body, but keen eyes will quickly spot mods like the carefully tucked bumpers, the missing door locks and the custom rear undertray that takes design cues from the GT bonnet.

Of course, what would be the point of all that top-notch gear keeping the chassis rails off the road if there was nothing under the bonnet but a worn old 302 Clevo for propulsion? After several engine builders left Tomi feeling less than well assured, he met Bill Kaglatzis at BK Race Engines and instantly knew he’d found the right man for the job. Bill stuffed a 9.2in-deck Dart block with some tasty spinning bits from Scat and Comp Cams and added a beaut sump from Jeff Johnston’s Billet Fabrication to control the slippery stuff. Up top, the Clevor wears Trick Flow PowerPort heads, a milled-down TFC single-plane and a Quick Fuel 950cfm carb, while ICE ignition gear sparks off nearly 700hp. Fred from Protrans screwed together a tough C4 to transfer power from the engine, while Mick at M&A Engineering sorted out the Strange nine-inch.

Details abound inside the XB, like the custom centre console with GT bonnet scoops at the top, the billet shifter surround and the CNC-machined heater control panel. The tubs and fabricated floor meant the rear seat had to be made from scratch, but Tomi made sure to keep it comfortable and usable for cruises with his family

With Tomi’s goal of 70s style with modern underpinnings amply covered, he’s keen to hit the road in the XB any chance he gets. “The car has turned out exactly as I envisioned it when I was 19,” he says with pride. You can’t ask for more than that!


As most readers will understand, there’s something special about driving older cars that more modern stuff tends to lack. When Tomi bought the XB, he didn’t really intend it to be his daily driver for nearly 10 years – he had an EL Series II XR8 for that.

“The EL was a much nicer car to drive than the XB,” Tomi says. “It was more comfortable and handled beautifully, but you just couldn’t get me out of the XB. I used to drive it everywhere when I was at uni; I even drove it around Mount Panorama a few times.”

Though it’s easy to read the plates as ‘so cool’, ‘sokol’ actually translates as ‘falcon’, and draws together Tomi’s family heritage and his love of local Fords

Of course, all of that changed when he decided to take the XB off the road for a bit of a tidy-up, and you can see where that idea led!
