I love watching busy test sessions such as this.

It’s the Thursday or Friday before the second round of the Australian Formula 2 Championship at Oran Park, New South Wales on August 5 1973.

The Birrana Cars onslaught is underway, Malcolm Ramsay and Tony Alcock’s 272 impressed all in 1972 including Leo Geoghegan who drove the car late in the year and was happily seduced back into single-seaters with a works Birrana 273 Ford-Hart 416-B 1.6 for 1973.

Leo mopped up that year winning six of the seven Australian Formula 2 Championship rounds despite opposition from Tony Stewart and Enno Buesselmann in 273s, Bob Skelton’s Bowin P6 and Ray Winter in the old darlin’- the ex-Gardner/Bartlett Mildren Yellow Submarine. Of these Skelton was quick everywhere and led Leo at Amaroo and Symmons, missed the last two rounds and ultimately could not convert the potential of the variable-rate suspension Bowin.

But all of that is in the future, the flurry of activity centres on Leo’s car and a back to back test between Goodyear and Bridgestone tyres- who is the the Goodyear tech looking closely at the right front- i am being assertive with my identification of people but in some cases ‘i think’ should be used- just letting you know rather than write it ten times.

Check-shirt man is Bruce Cary, the driver at left is Ray Winter, to his right in the short sleeved shirt is Bruce Richardson- the car in front of Leo’s is Tony Stewarts, the guy in the Singapore Airlines T-shirt is Malcolm Ramsay and the car at the end of the pitlane is one of the black Bowin P6s- either Skelton’s or Bruce Allison- Bob liked the car more than Bruce!

Goodyears in the first shot, Bridgies here.

All of the Birranas are superb racing cars- FF, ANF3, ANF2, F Pac and the mid-engined Speedway machine, Adelaide strikes again! Those who have driven both cars either say the 273 was a better car than the tidied up in the body and bracketry 274, or its equal- Bob Muir gave Leo ‘absolute buggery’ in the 274 bodied 273 owned by Bob and Marj Brown in 1974 didn’t he?

Note the mounts on the nose to accept another small wing- in search of more front bite.

Business end with Varley battery and oil catch tank- forward of them is a Hewland FT200 five speed transaxle and the Brian Hart Ltd, Harlow, Essex built ‘416-B’ Lotus-Ford DOHC, two valve, Lucas injected four cylinder motor.

This engine was aimed at the large American Formula B market, where all of the British tuners fought a pitched battle and in much smaller numbers Australian F2.

The ‘ducks guts’ variant was alloy blocked, the late Peter Nightingale, who looked after Leo’s and Geoff Brabham’s Harts amongst others quoted 200bhp @ 8500rpm and 130lb/ft of torque @ 7500rpm for the 1973 iron block variant and a ‘minimum’ of 200bhp @ 8500rpm and 125lb/ft of torque @ 8500rpm for the 1974 alloy block.

Line ball call but the alloy block was lighter and in the very best of hands every liddl’ bit counts.

No idea who blondie is but the vertically challenged fella looking at the engine in front is ex-Repco immensely talented engineer and multiple Australian hillclimb champion Paul England looking at Tony Stewart’s Jack Godbehear built engine.

Oh yes, come raceday Leo won from Peter Brock’s 273 and Bob Skelton, i am intrigued to know what tyres the works 273 raced…

Tailpiece…

Leo is ready to boogie- fuel check and off. Bearded Ramsay, tall isn’t he, wandering past.

I’ve often wondered what Tony Alcock could have achieved in his second European stint, as most of you know he was in that plane, on that day, and in those circumstances with Graham Hill in 1975.

Finito…

    Excellent commentary and period photographs, Mark. Thanks too for taking the time to put names to faces in the photos. Glad I found this newsletter and your site.

    I am passionate about the old F2 scheme, it was perfect, 2 liters for engines with a maximum of 4 cylinders would be ideal even today, I never liked the F3000, only Bernie won with that.
    The chassis diversity was wonderful, I still dream of a future like that, who knows, mono-brands are like biting into a chocolate without removing the packaging.
    I had a lack of knowledge about this chassis, thanks Mark for these old news, a beautiful and pleasant post !!!

      Jonny,
      I was a big fan of 2 litre F2 as well, and happy for the variety the Renault, Ferrari and Honda V6s provided. Maybe the one-make era will pass but i don’t see it happening soon.

    Mark, In the second photo down, I doubt that is Derek Kneller in the Goodyear overalls. I think Derek is taller than that bloke. The person you name as Evan Green is actually Bruce Richardson, a well known mechanic and car builder.
    Dale.

      Thanks Dale,
      I thought i might have gotten a rise out of Derek but he has clearly given up reading my nonsense! Which of the cars was Bruce looking after? Many thanks, have changed the words accordingly.
      Mark
