The Birrana 272 was a monocoque Australian Formula 2 car, constructed by Alcock in Adelaide for South Australian racing driver Malcolm Ramsay. The 272 won the Australian Formula 2 class on its debut at the Sandown round of the 1972 Australian Drivers' Championship in April. It was later sold to Peter Brock, and subsequently won the opening round of the 1973 Australian Formula 2 Championship in the hands of Leo Geoghegan.
