A 250-cubic-inch six-cylinder engine and three-speed manual transmission with column shift remained standard equipment through the 1973 model year on sedans with the 350 V8 and automatic standard on wagons—the Turbo Hydramatic automatic had been the sole transmission choice on V-8-powered Bel Airs since the spring of 1971 though the old two-speed Powerglide was still offered with the six-cylinder engine through the 1972 model year. Only about 1,400 cars were built with the inline six in 1973. The engine and manual transmission were shelved by the end of the model year—marking the last full-size body-on-frame American car to offer a manual gearbox.
