1970 Chevrolet Chevelle SS 454 LS6 Documented Coupe

Current eBay Auctions

The Chevrolet Chevelle is a mid-sized automobile which was produced by Chevrolet in three generations for the 1964 through 1977 model years. Part of the General Motors (GM) A-Body platform, the Chevelle was one of Chevrolet’s most successful nameplates. Documented as one of the greatest Chevelle’s ever produced, the 1970 Chevelle was the highest powered Chevelle manufactured in the model’s lifetime, which ran from 1964 through 1977, and was the only GM car at the time to have ever topped the horsepower rating of the Corvette with its LS6 Model.

 

 

 

In the hierarchy of the street, circa 1970, there were the Big Dogs and then there was everyone else. Having 400 cubic inches under the hood didn’t cut it anymore at the Stoplight Grand Prix. The name of the game was horsepower and the more grunt the better, and more grunt meant more cubic inches and more horsepower. The old standard “there’s no replacement for displacement” was never truer in 1970, and sitting atop the muscle car food chain was Chevrolet’s SS Chevelle. Not just the garden variety, 360 horsepower SS454, but the King Kong of the Bow Tie brigade, designated RPO Z15. Checking off this option delivered a 450 horsepower, 454 cubic inch solid lifter behemoth that cranked out 500 lb/ft. of torque and bludgeoned any challengers for its title as King of the Streets.
