Chevrolet’s 454 SS truck hit the streets in 1990. It was powered by a massive big-block V8, delivering up to 255 hp. On sale until 1993, the 454 SS made truck fans go oooh and aaah while the oil barons smiled from ear-to-ear as the 7.4-liter truck guzzled gas faster than an aircraft carrier. In 1994, the thundering 454 SS was replaced with the S-10 SS. In the new SS, the vintage 454 V8, originally hailing from 1970, made way for a more modern 4.3-liter V6.
