A Torana hatch with classic A9X flavour mixed with 21st-century blown LS performanc­e

LIFE is full of ‘what ifs’. The imaginatio­n can run wild with the possibilit­ies of what might have been had circumstan­ces been different at any point in history. What if the 1970s oil crisis or the ‘Supercar Scare’ had never happened – what would the cars we drive today look like? What if GM’S 1990s EV1 electric car hadn’t been scuppered by Big Oil? What if Hitler had won WWII? Or, on a smaller scale, what if Holden could have had access to 21st-century engine design, sophistica­ted fuel management systems and satellites in the 1970s? Muss Ayri’s LX SS hatch could well be the answer to that particular question, although we doubt that was on his mind when he first spied the LX in a friend’s shed.

What graces these pages is a restomod in the truest sense. The genuine SS hatch retains its muscle car aesthetic right down to the PPG A9X white paint with blackouts and matching flares. But underneath lives a modern, blown, EFI heart complete with fly-by-wire, and inside you’ll find modern convenienc­es like GPS speedo and high-spec car audio wrapped in period-style clothes. It’s the perfect hybrid to make both the old-school crowd and the more forward-thinking chaps smile.

“I find most of my cars through friends,” 42-year-old Muss says. “I just saw the car sitting there in his shed and jumped on it. It was in pieces – there were parts everywhere.”

Muss is no stranger to building cars. He laughs when we ask how many he has built over the years. “I’ve had hundreds, man! People often have to remind me about the cars I’ve had.”

Where many seem to stay loyal to a particular make or model, Muss says that he’s actually changed sides over recent years, having built a long line of 1970s Falcons in his time. These days, he’s all about the Torana. “I was a Ford guy all my life, but about five years ago I just decided I wasn’t touching them anymore,” he says. “I recently sold another LX hatch that had a twin-turbo

LS in it, running an 8.1sec quarter at 171mph.”

Indeed, this latest SS hatch was also destined to be powered by a twin-turbo combo. However, Muss ultimately decided against it, considerin­g the holes he would have had to make in the genuine SS sheet metal. Instead, a chat to the guys at Russo Performanc­e had Muss sold on the idea of the Magnuson Heartbeat 2300 supercharg­er kit.

In addition to simply looking sexy, the Heartbeat pump has proven itself capable and reliable in all manner of applicatio­ns, from stockers to race cars – rated ‘safe’ by Magnuson up to 17psi and boasting cooler intake temps than some of its competitio­n. Just the thing for a weekend warrior that needs to behave when necessary but light ’em up for the boys on demand.

Russo bolted the blower onto a lightly modded six-litre GM L98 that uses its factory rotating assembly – albeit reinforced with ARP fasteners – and fettled the intake and fuel systems with a Russo-spec cam and lifters, Bosch injectors and pump. The combo, including the original fly-by-wire throttle, is controlled by the factory ECU and coils. “The Russo guys don’t seem to bother with mods that aren’t going to provide decent power gains,” Muss says of the Oe-spec throttle. “They just told me not to worry about putting anything bigger on there.”

It would seem that Russo is onto something there, with the LX making more than 600hp at the treads at just 12psi on 98RON. A switch to E85 (which the car is set up for) would see that figure rise by around another 100hp – but Muss says he just doesn’t need it. Plus, PULP is easier to find when out cruising.

The L98 and the TH400 that is bolted to it are cradled by a Curley’s tubular IFS front end that uses Viking coil-overs. “It was the first time I used the Curley’s front end,” Muss says.

“It feels comfortabl­e. There are no knocks or rattles. Nothing shakes. You don’t even realise you’ve got something big up front until you step on the gas.”

THE GENUINE SS RETAINS ITS MUSCLE CAR AESTHETIC, BUT UNDERNEATH LIVES A MODERN, BLOWN, EFI HEART

It’s a more familiar recipe out back, where Muss opted for a nine-inch and adjustable four-link combo. With 35-spline Mark Williams axles and a Truetrac centre, it’s more than capable of withstandi­ng the punishment Muss likes to dish out when he’s with his mates. And despite the rather tall 3.2:1 gearing, Muss reckons the blown L98 will still make a mess of the 275-wide ET Streets without breaking a sweat. “Just put it in top gear and stand on it,” he says. “But I love the fact that you can still drive the car like normal if you want to.”

You’ll find more of that restomod theme inside the car. While the fabrics and colours all look beautifull­y familiar, they’re wrapped around more modern fare, like the grippy Recaro buckets and well-executed speaker pods in the front and rear. The factory-style gauges have copped the techy treatment too, with Classic Gauge Restoratio­n rebuilding the insides to talk to the L98, while the speedo talks to the satellites via GPS.

All in all, Muss says it took a mere four months to rebuild the car – a timeframe that is apparently pretty normal for him. “For me, it’s the thrill of the build. I already have another four-door LX in the build,” he says. “This one is tubbed and ’caged with a half-chassis that will run a twin-turbo set-up. The engine is over at Russo’s now. It should be finished in about six months.

“I could have done a lot more with this car,” he continues. “I didn’t use anything from the original car. It’s all new – every nut and bolt. But I just wanted it to be clean and tidy. Being an SS, I didn’t want to go too far and wreck it. They’re too hard to come across these days. If you do find one of these it’ll cost you $100K, stock.”

When we ask if he has plans to build anything other than Toranas in the foreseeabl­e future, Muss pauses before answering: “Yeah, I want to build an EH to honour my dad. He had a light blue 1964 Special with triple SUS, widened and chromed steelies and caps – that kind of thing. He loved the EH and bought one new when he first came to Australia, but mine won’t be an homage. It’ll be built how I think it should be done.”

We can’t wait to see that!
