Ford Falcon GT HO 351
Perhaps the most famous of all Australian muscle cars was the mighty Falcon GT HO 351, introduced in 1971. Despite its performance portfolio, it was still a four-door sedan but with proper muscle car equipment. Under the hood was Ford’s 351 V8 with a shaker hood, beefed-up suspension, and brakes. Its power output was 300 HP for the standard version, but Ford offered Phase II and Phase III options. The car looked the same but was better. In the ultimate Phase III version, the Falcon GT HO had over 350 HP (via Supercars).
The performance was astonishing a 0 to 60 mph run in six seconds range and a top speed of over 140 mph. As expected, the Falcon GT HO was successful at racing, dethroning its archenemy Holden Monaro GTS 350. Remember, this was the time when Falcon in the USA was an economy car. But in Australia, it was a well-respected four-door muscle model with a racing pedigree.
