Recorded with Tascam DR-05 with in-built microphones April 2013 at the local round of the New South Wales/ACT State Hillclimb Championship Series, Fairbairn Hillclimb Circuit, Canberra.

Vintage Formula ??? Race Car with in-line General Motors 6-cylinder race prepared engine, midships, chassis reminded me of 1960’s Formula Aus racecar, open-wheel, about size of Formula Ford but longer. Engine was a General Motors Holdens 6-cyl inline donk from a road sedan. This engine was built in Australia from just after WW2 until the late 1980’s and is very similar, if not almost identical, in design to the GM Chevrolet 6-cylinder engine of the same era.
The smooth sounding engine featured race-strong interals, wild camshaft profiles, triple Webber twin side-draft race carburettors, and straight open exhaust headers out the rear, overtop a Hewland straight cut race gearbox in the rear.
The engine is started, and the race car moves off towards the starting line for the hillclimb run.
