632 cubes, three ni­trous kits, 1270hp in to­tal – Heath Do­herty’s LH To­rana is kick­ing arse and tak­ing names

HEATH Do­herty can pin­point the ex­act mo­ment in time when he be­came com­pelled to build a balls-out, big-block ni­trous car. “It all started at Calder Park in 2012 when Si­mon Kryger first brought his Ca­maro out,” he says. “I saw it run at night time, and it just blew me away. That was the turn­ing point; from then on I wanted to build a big ni­trous car.”

Watch­ing Kryger’s Ca­maro charge down the Calder Park quar­ter-mile with the can­dles lit was all the mo­ti­va­tion Heath needed. He promptly bought a To­rana hatch and an en­gine to power it, but when he got wind that the 632 out of Johnny Wil­son’s STAUNCH To­rana was up for sale, it was too good an op­por­tu­nity to pass up. The only prob­lem was, the big 632-cu­ber would al­most cer­tainly have torn his hatch clean in half.

“Around that time, Krygs had the SUB­TLE To­rana for sale as a bare roller, so I jumped on it,” Heath says. “It was a killer car that had al­ready gone 6.5s with a turbo combo.”

With a Pro­fab three-quar­ter chas­sis and runs al­ready on the board, the To­rana was a great start­ing point for the ni­trouss­nort­ing fire-breather Heath knew he needed in his life, but he had to make it his own. En­list­ing Kryger to project-man­age the build, Heath pro­ceeded to work his arse off to keep funds up to the money-hun­gry Torry.

DRC Group’s Dave Corn­ford took care of the body, which, aside from the roof and rear quar­ters, is all fi­bre­glass. He also ap­plied the killer duco, a cus­tom hue mixed to Heath’s taste. “Dave killed it with the body and paint,” he says. “He’s a whiz with fi­bre­glass and all the gaps are per­fect. I don’t even know what to call the colour; it changes com­pletely from grey to green depend­ing on the light.”

The en­gine was fresh­ened by Sam at Wes­tend Per­for­mance, and it sports all the good gear, from the twin 1250cfm APD ni­trous carbs up top to the Stef’s alu­minium sump down be­low. The in­take man­i­fold is a CFE sheet-metal item with bil­let run­ners, mated to a set of Big Chief 16-de­gree heads with ti­ta­nium valves. GRP al­loy rods swing off a Cal­lies Mag­num crank, with forged pistons specced for a lofty 15.5:1 com­pres­sion ra­tio. It’s handy for 1270hp on Roo16 (a neat 2hp per cu­bic inch nat­u­rally as­pi­rated), plus a whole lot more once all three kits of ni­trous are do­ing their col­lec­tive thing. “Sam is un­be­liev­able,” Heath en­thuses. “He al­ways makes time for me even though he’s flat-out.”

Around 2000hp in to­tal heads south via a full-house Turbo 400 and a three-inch chrome-moly tail­shaft to a full-float­ing, 40-spline sheet-metal nine-inch. All four coil-overs are Strange units, while Wil­wood brakes and a match­ing pair of Simp­son ’chutes haul

I SAW SI­MON KRYGER’S CA­MARO RUN AT NIGHT TIME, AND IT JUST BLEW ME AWAY. THAT WAS THE TURN­ING POINT; FROM THEN ON I WANTED TO BUILD A BIG NI­TROUS CAR

EN­GINE: The mo­tor is 632 cubes of awe­some – it makes around 2000hp with beast mode fully en­gaged, and breathes out through a set of 2.25in head­ers

EX­TE­RIOR: The rear whee­larches were stretched to ac­com­mo­date 32-inch tyres, while the many fi­bre­glass body pan­els were supplied by Alfa Mo­tor­sport Fi­bre­glass. The stun­ning cus­tom-mixed paint was laid on by Dave Corn­ford. Ul­ti­mately, ARMED is pretty damn neat for a race car. “It wasn’t sup­posed to be like that,” Heath says. “It’s prob­a­bly Dave Corn­ford’s in­flu­ence, but it’s turned out al­most like a show car”

THE 632CI CHEV IS HANDY FOR 1270HP ON ROO16, PLUS A WHOLE

IN­TE­RIOR: Framed by a chrome-moly ’cage, the cock­pit is all busi­ness. Kirkey race seats with Simp­son har­nesses, a Strange steer­ing wheel, Ra­cepak dash, Pre­ci­sion shifter and acres of car­bon­fi­bre are all about stay­ing light, in­formed and in con­trol

CHAS­SIS: The front rails are still in­tact to meet Pro Street reg­u­la­tions, but from there back the chas­sis is all hand­built by Pro­fab

LOT MORE ONCE ALL THREE NI­TROUS KITS ARE DO­ING THEIR THING

the To­rana back down to saner speeds af­ter Heath has emp­tied the ni­trous bot­tles.

The car made some test hits in the lead-up to the in­au­gu­ral Grudge Kings Syd­ney event, with some re­ally en­cour­ag­ing re­sults. “I’m still learn­ing the car at this stage, so Si­mon drove it first time out,” Heath says. “It ended up go­ing 7.7@181mph on one kit, but the con­verter wasn’t right. We’re chas­ing a six, and Krygs is all over it; he’ll get it go­ing.”

With Si­mon and fel­low ni­trous afi­cionado Mark Hayes in his cor­ner, Heath is sure to get the re­sults he’s af­ter. “Hayesy is an ab­so­lute guru,” he says. “He and Si­mon are prob­a­bly the two best ni­trous guys in Aus­tralia, and hav­ing them both in the pits read­ing plugs and help­ing out with the car is un­real. They’re old-school, but they’re the best.”

The car can run in ei­ther Pro Street Blown or Out­law 10.5, but Heath tells us that the fo­cus will be on Pro Street un­til he con­verts to EFI and gets a big­ger en­gine. Yep, big­ger than a 632ci! “The goal is to get an 800ci-or-big­ger mo­tor for it,” he says. “Si­mon has had his 800-cu­ber mocked up in it – it fits, so that’s the plan.

“The build went so well be­cause I’ve had the best peo­ple around me. Be­tween Krygs, Mark and Sam, I was laugh­ing,” Heath con­cludes. “I want to run it in a lot of the Lights Out and Grudge Kings-style events, and I just can’t wait to run it at night – I want to s see those flames!”
