1971 Plymouth GTX
1971 was the final year for the GTX as a standalone model; it was completely redesigned for this year. The 440 engine was still available. Emission restrictions such as lower compression ratios and faster-acting choke operation lowered the output by 5 hp, down to 370 hp. The 440 Six Barrel was down to 385 hp, but the Hemi was still rated at 425 hp. Due to rising insurance rates on muscle cars, sales were low and that spelled the end of the GTX and the Hemi engine. |
