Peter Brock in his Birrana 272 Ford at Winton in 1973…
Brocky was very hot property in 1973 having seized the public spotlight with the last solo Bathurst win aboard his Holden Dealer Team Torana GTR XU1 in October 1972. Every young bloke in Australia wanted to emulate him, and many women wanted to shag him, including Miss Australia as it transpired!

Purists were delighted when he bought 272-002, Tony Alcock’s first monocoque Birrana to contest the Australian F2 Championship, but sadly he didn’t race the car for long, soon returning to the touring car ranks.

Tony Alcock’s first Birrana, the F71 Formula Ford was built in Sydney and initially raced by one of Brock’s touring car sparring partners, John Goss. Then Tony returned to his Adelaide home town and started to build Birrana’s in numbers in partnership with Malcolm Ramsay- in 1972 building two F72 Formula Fords and 272-002. Their first ANF2 car was raced by Ramsay, dual Australian F2 champion Henk Woelders and Gold Star champion Leo Geoghegan before being sold to Brock.
Brock Birrana 272 Ford, Oran Park 1973, note the ‘Isuzu-GM’ decal. Car powered by an injected Lotus-Ford twin-cam but not the ‘ducks guts’ 205 bhp Hart 416B twin-cam which came into F2 in big numbers from that year (unattributed)
Brock, Birrana 272 Ford, Hume Weir, 22 April 1973 (R Davies)
Where is Ian Tate when I need him?- PB looking for a mechanic. Birrana racing very much a DIY affair with father Geoff Brock. 272 at Hume Weir in 1973 (D Oliver)
PB raced it at Hume Weir, Winton and Oran Park to get his hand in prior to the start of the 1973 F2 Championship which commenced at Hume Weir in June.
Brock was 2nd to that years champion Leo Geoghegan at Oran Park on 5 August and then 6th at Amaroo on 19 August, in a Birrana 273, chassis 273-008. He updated to the best car of the season, Geoghegan galloping to the title with wins in every round but one. Its not clear exactly how many meetings Brock did in the two cars but he certainly raced the 272 at Hume Weir, Winton, Calder and Oran Park and the 273 at Oran Park and Amaroo Park.
Brock, Birrana 273 Ford, Oran Park 5 August 1973- he was 2nd in the AF2 championship round that day to Geoghegan’s ‘works’ 273 (autopics)
Running the Lotus Ford twin-cam engine was said to be a commercial barrier to the continuation of Brock’s F2 program given his Holden Dealer Team contract, but perhaps the reality of running his own car again with the assistance of his dad was just all too hard compared with being a works driver with all of its benefits. It was such a shame, Brock’s sublime skills deserved to be deployed in racing cars as well as the tourers of all sorts in which he excelled.

Brock’s talent was clear from the start aboard his Holden engined Austin A30- his aptitude very quickly accepted once others drove that car, none of those who raced it or track-tested it could work out how he did the times he did- not Ross Bond, Peter Wherrett or Rob Luck. The little rocket was a mix of lightweight Austin stripped shell, highly modified Holden 179 6 cylinder ‘red motor’ giving circa 200 bhp using triple 2 inch SU carbs, Holden three, and later four speed ‘box, rear axle assembly wheel to wheel with a Holden front end and Triumph Herald steering rack with disc front brakes and drum rears.
In the crude but fast HDT Torana XU1 Repco Holden F5000 V8 engined ‘The Beast’ sports sedan, Calder circa 1975 (unattributed)
During the early-mid seventies glory F5000 years it always seemed to me the union between Holden and Repco would see him aboard a big, powerful single-seater car at some point, but the closest that ever came to fruition was the Repco Holden F5000 V8 engined Torana sports-sedan ‘The Beast’, which was not exactly what I had in mind at all. Still, what was in that for Holden or Repco I guess? Holden sold sedans not racing cars, so they hardly needed PB racing one of those dangerous things and Repco’s works F5000 driver was Frank Matich. A guest drive in a Matich would have been nice all the same…
In the Bill Patterson Group 5 BMW CSL 3.5 litre at Le Mans in 1976 with Brian Muir. Q48 and DNF with gearbox problems, the race won by the Ickx/Van Lennep Porsche 936 prototype, the best placed Group 5 entry was the 4th placed Schurti/Stommelen Porsche 935 (unattributed)
Marshall/Brock first in class and second overall in the 1977 Spa 24 Hour, Vauxhall Firenza Magnum 2300, 23 July 1977. The Joosen/Andruet BMW 530i won (unattributed)
Steps in the right direction were his international drives at Le Mans in 1976 aboard a Bill Patterson supported BMW 3.5 CSL Group 5 machine paired with Aussie International Brian Muir. Now that would have been a career to emulate in terms of a mix of sedans and sportscars based in the UK?
Spa in a works Vauxhall Firenza Magnum 2300 paired with Gerry Marshall yielded an amazing second outright in the 24 Hour classic in 1977.
Brock’s status as one of the best Touring Car Drivers of them all was confirmed by MotorSport in 2005 who rated him the greatest in an article contributed to by an array of global commentators of the top-20 of all time.

The Bob Jane supported attempt on the 1984 24 Hours of Le Mans, with Brock partnered by Larry Perkins in a customer Porsche 956 captured all of our imaginations and to me was exactly where that pair belonged and deserved to be. Sadly the warm-up Silverstone 1000 Km and Le Mans was as far as it went. At Le Mans they retired after an LP mistake during the night.
Rallycross at Calder circa 1971- HDT supercharged ‘LC’ GTR XU1- this car earlier in its life doubled as a sports sedan on the circuits as well as in the dirt and mud (autopics)

If only Brock had raced the 1974 Australian F2 Championship in a good car amidst one of the best grids of any single-seater championship in Australia ever- with success his career direction may have encompassed racing cars as well as tourers, rallycross, rallies.
Not half versatile was he?

Mark,
I believe that the wording in the caption to the last photo should read “…won by Moffat’s Ford Falcon XB GT Hardtop” (rather than XB GT Coupe). Ford Australia marketed their two door XA, XB and XC models as Hardtops, e.g. in their brochures.
Cheers Rob,
Rather nice things they were too- I had a buddy with a Phase 3 HO but another friend had an XB GT Hardtop manual which was much nicer round town.
