1970 Chevrolet Chevelle LS6 454/450/500 HP, 4-Speed

 

The year 1970 saw the birth of the Chevelle SS454 LS6, the largest-displacement and most powerful Chevrolet muscle car built to that time and the enduring champion of the muscle car wars. One of the handsomest cars of the era, the 1970 Chevelle and the LS6 engine, which the factory underrated at 450 HP and 500 lb-ft of torque, were a marriage made in muscle car heaven. The LS6 big block engine was packed with all the time-tested horsepower-producing technology, including a forged steel crank in beefy 4-bolt mains, forged steel connecting rods and aluminum pistons, a high lift, high duration solid lifter cam, an 800 CFM Holley 4-barrel on an aluminum dual plane intake manifold and gargantuan intake and exhaust valves in high flow heads.
