1970 Chevrolet Chevelle

1970 Chevrolet Chevelle SS 454 â?" LS5 Big Block, TH400, F-41 Suspension, 12-Bolt Rear Why This Car Is Special The 1970 Chevrolet Chevelle SS 454 is widely considered the high-water mark of the muscle car era. It was the first year Chevrolet offered the 454 cubic inch big block in the Chevelle, and it arrived in two states of tune â?" the LS6, rated at 450 horsepower, and the LS5, rated at 360 horsepower. The LS5 was no consolation prize. It was a hydraulic-lifter engine built for street durability with serious torque â?" 500 lb-ft at 3,200 rpm â?" and it was paired with the Turbo-Hydramatic 400 automatic transmission, one of the strongest units GM ever put behind a big block. That combination made the 1970 Chevelle SS 454 LS5 a practical, driveable car that could still run mid-13s in the quarter mile in stock trim.
