16. Pontiac Trans Am SD455
By 1974, almost all muscle cars were extinct from the market. And sadly, those that remained were robbed of their power and style. However, there was one model that managed to survive and offer as much performance and power as possible – the 1974 Trans Am Super Duty 455 (via Motor Trend).
They carried the SD 455 model over from 1973, but in the new package, it featured a better suspension and brakes. The standard 455 V8 produced only 215 HP, but in SD trim it developed 290 HP, which was absolutely fantastic for 1974.
