engine. Emissions and low-lead fuel requirements had become more strict for 1972. To meet these requirements, compression ratios on all Torino engines were dropped to at least 8.5:1, and all engines ran on regular gasoline. These engines generally produced less power than their predecessors in 1971, although this was exaggerated due to the switch to the new SAE net bhp ratings from the SAE gross figures used in 1971. As a result, the power loss was not as dramatic as the numbers suggest, and the horsepower figures are not directly comparable. All models came equipped with a three-speed manual transmission as a standard equipment. The Cruise-O-Matic was optional, but was a mandatory option for the 351-2V, 400-2V and 429-4V. The 351-4V CJ required either the 4-speed or the Cruise-O-Matic transmissions as mandatory options. The only performance engine for 1972 was the 351-4V CJ. The 351-4V CJ offered a number of performance enhancing features not offered on the 1970–71 351C-4V. It included a special intake manifold, modified camshaft, special valve springs and dampers, a 750 CFM Motorcraft Carburetor, 4-bolt main bearing caps and dual exhaust. Dual exhaust and the 4-speed transmission option were exclusive to the 351-CJ. A Ram Air Induction system was available briefly during the early model year, and could be equipped on 351 CJ and 429 powered cars. Performance from the 1972 351 CJ was competitive with the 1970–71 Torinos with the high compression 351-4V. Car and Driver tested a 351 CJ, 4-speed Gran Torino Sport SportsRoof with 3.50:1 gears to have a 0 – time of 6.8 seconds. Car and Driver did not publish its quarter-mile times, but Cars magazine tested a Gran Torino Sport SportsRoof with a 351 CJ, C-6 automatic, and 3.50 gears to run through the quarter-mile in 15.40 seconds. The Gran Torino Sport was offered in two body styles: A 2-door formal hardtop and a 2-door SportsRoof. The Gran Torino Sport included an integrated hood scoop, twin colour-keyed racing mirrors, molded plastic door panels unique to the Sport model, body-side and wheel lip moldings, and F70-14 tires (E70-14 on hardtop models). A revised full body length laser stripe was an option for all Torino 2-door models. It replaced the chrome side moldings and was available in four colours to match the exterior paint. Ford offered an option package for the driving enthusiast called the "Rallye Equipment Group." This grouped all the performance options
