Under the hood is a 340ci V8 with a 3-speed automatic transmission. This Road Runner has a few upgrades including MSD ignition, headers, 4150 Holley, and an aluminum intake. From the factory, it came equipped power brakes, power steering, and a heater. Being from Arizona where it has spent most of its life the... body is exceptionally clean. For more information please contact us today. The 1973-74 models received completely new sheet metal and had more conventional squared-up front-end styling and changes to the rear that more closely resembled the four-door models than the 71-72s. In addition, the interior options included retaining power seats and windows as well as offering plusher carpeting and seat covers, moving the car to a slightly higher level of luxury. The restyling helped sales which were up 40% over the 1972 models.
