18. Oldsmobile 442 W30
The 1970 model year was big for the Oldsmobile 442 and all GM muscle cars. General Motors lifted its corporate ban on putting engines bigger than 400 CID in intermediate bodies. So all GM muscle cars including the 442 got the big block and more power. But in 1970 the 442 got the mighty 455 V8 with 370 HP and 500 lb.-ft of torque.
Since the 442 was more luxurious than other muscle cars, it was also somewhat heavier. This made it a little slower. However, it was still an extremely capable machine with 0 to 60 mph times of 5.7 seconds (via Motorious).
