1970 Chevrolet Chevelle

1970 Chevrolet Chevelle SS 454 â?" Cranberry Red, LS5 Big Block, TH400, 12-Bolt Rear Why This Car Is Special The 1970 Chevrolet Chevelle SS 454 sits at the top of the muscle car hierarchy, and it has for more than fifty years. This is not an opinion â?" it is a market fact backed by auction results, collector demand, and the simple reality that no other GM A-body of the era was offered with as much displacement from the factory. The 454 cubic inch big block was new for 1970, and Chevrolet offered it in two states of tune: the LS6 at 450 horsepower and the LS5 at 360 horsepower. The LS5 was the more streetable of the two, making it the version most buyers actually ordered. It was hydraulic-cammed, emissions-friendly enough for daily use, and still capable of running the quarter mile in the mid-13-second range in period testing.
