HARRY’S TURBO BIG-BLOCK HQ HOLDEN AT DRAG CHALLENGE - FULL STORY

VICTORIAN Harry Haig had a huge 2016, and all the time spent planning and preparing for his Hot Rod Drag Week assault in the infamous SS Chevelle meant that his eight-second HQ missed out on some love in the lead-up to Street Machine Drag Challenge.

An 8.75 at Heathcote showed that things weren’t improving and the guys headed for Mildura – and that’s when shit got serious.

With plenty of help from Robby Abbott, they swapped in a new roller lifter for racing, but in the rush to get everything back together, an intercooler pipe was left loose and it popped off and punctured the radiator during the run.

Using the workshop at BT Performance, the guys did the cam and lifter swap, but now the pushrods were too short. They tried some small-block ones to get it back on the road, but the thin pushrods bent like spaghetti. So with a mixed set of pushrods and fingers crossed, Harry headed down the strip – and punched a rod through the sump.

Then a bloke who calls himself the Wollinator volunteered to drive the parts up to Swan Hill overnight. “He got to Swan Hill at 4.20am, had a beer with us and then drove back to Melbourne for work the next day.”

However, this story doesn’t have a fairytale ending; the oil pressure disappeared once they got travelling and the engine seized a solid 30km from Calder Park.

Harry Haig Drag Challenge 2016“It was the toughest event I’ve ever done; it made that first year with the Chevelle at Drag Week seem like a trip to the shops,” Harry said. “But it was still awesome to race and cruise with 100 of the toughest cars around. No egos, no fighting, just good times. It was the greatest, coolest thing I’ve ever done with my son Corty too. We’ll be back next year.”
