The 1972 Road Runner was nearly identical to the 1971, but with a few exceptions like new grille design, new taillights designed to match the new aerodynamic look of the grille, and new side marker lights.
The big differences came in the suspension, rear axle ratios, and the engines. The 383ci was replaced by a larger bore, and poorer-performing, 400ci V8. A 440ci V8 with 1x4bbl was availalbe. All the engines suffered a loss in performance with lower compression ratios to use unleaded regular fuel, as well as to meet the first round of emissions regulations.
The 426 Hemi was no longer available, and only five 440 3x2bbl cars were produced before that engine was also dropped (it couldn't meet the new emissions restrictions).
