well and could, theoretically, run the entire race on a single tank of petrol, but the larger-engined cars were faster in a straight line. Ford's development of the 289 cubic inch V8 Ford Falcon GT signalled the end of small cars as outright contenders. 1967 was also the first year that starting grid positions were allocated according to practice lap times rather than by class groupings. This was also the first year that an official trophy was awarded to the first team to cover the 500 miles. The 1967 victory of the XR Falcon GT over the smaller Alfa Romeo 1600 GTVs and Mini Coopers surprised many pundits as the Falcon GT was unproven. The highly regarded, and more expensive, Alfa GTV had been seen as the emerging force in touring cars. However, the Falcon GT's V8 power was well suited to the Mount Panorama circuit, particularly on the long straights. Thus was forged the adage that "there is no substitute for cubic inches", which became synonymous with racing at Bathurst. Initially the Geoghegan brothers' Falcon was awarded victory but some hours later Harry Firth and Fred Gibson were declared winners. During the race the Geoghegan car had entered the pit area through the rear access lane off Mountain Straight and erroneously accumulated an extra lap on the ARDC timing board. Third place in Class D fell to the venerable Studebaker Lark of Warren Weldon and John Hall. Class E was won by Doug Chivas and Max Stewart in an Alfa GTV. Classes B and C were won by variants of the Mini and Class A was won by a Datsun 1000 piloted by John Roxburgh and Doug Whiteford. The popularity of the race grew rapidly during the 1960s. Most Australian manufacturers and assemblers became heavily involved. A good result in the long and tough race added credibility to the car and its brand, especially in terms of performance, durability and reliability. An outright or class victory was a significant opportunity to increase sales and market share. It was during this period that the famous Holden-Ford-Chrysler rivalry originated. The production car battle between the "Big Three" was fought at Bathurst. This rivalry spawned Australia's most famous muscle cars, reverentially known as "Bathurst Specials". Ford's Falcon GT and later GT-HO, Holden's Monaro and Torana, and Chrysler's Pacer and Charger models were the result of constant development of race-worthy cars that the
