1970 Chevrolet Chevelle SS 454
The Chevy Chevelle enjoyed a 15 year production run between 1963 and 1978, but undoubtedly the 70 SS 454 was the crowning achievement. Looking at the 69 model compared to the 70 SS is like viewing two completely different brands.
Interesting fact: the Buick and 70 Chevelle SS are the only two muscle cars in existence to share the exact same roof line. Many other sheet metal parts were also interchangeable between the two GM motors.
The base 454 cid engine was rated at 360 hp (which was also available with cowl induction) and the optional LS6 version at 450 hp. There were 4,475 LS6 Chevelles produced, of which 137 are currently registered on the National Chevelle LS6 Registry.
