When Chrysler realized muscle-car fans of the 1960s wanted a high-power, no-frills car at reasonable costs, they responded and came up with the Road Runner. The company paid Warner Bros $50,000 to use the cartoon character's name and logo on the car, and although the forecast was sales of 2,500, the Road Runner was such a success it sold 44,589. It used uprated torsion bars at the front and leaf springs on the live axle, which had 3.23:1 gears though higher ratios for better acceleration were available. The engine was the basic cast-iron big-block which had been in production since the 1950s, in this form displacing 383ci (6,276cc) but putting out tremendous torque. The heads, camshaft, and exhaust were all from the 440ci (7.2-liter) motor. Despite its size, the Road Runner in basic form was relatively lightweight and performed well, making it an instant classic.
