1970 Chevrolet Chevelle SS The Chevrolet Chevelle SS represented Chevrolet's entry into the hot midsize muscle car battle. The Chevelle SS was the high performance version of Chevrolet's Chevelle, and had its own line of engines and performance equipment. The Chevelle, along with the Pontiac GTO, remains one of the most popular cars from this era and with good reason. 1970 saw the introduction of the most powerful Chevelle SS of all time. Responding to the lifting of GM's ban on engines larger than 400 cid in midsize cars, Chevrolet responded by dropping in a new 454 cubic engine into its Chevelle SS. The entry level 454 was known as the LS5 and packed 360bhp. The top engine choice was the LS6 version with 450bhp. Optional on both the 396 and 454 was a new cowl-induction hood, which had a rear facing flapper near the base of the windshield to feed air into the engine. The styling was new with a "vee" front end, functional hood pins, and five-spoke Rallye wheels. This was truly the pinnacle of the Chevelle SS performance.
