1970 Chevrolet Chevelle LS6 Convertible

This 1970 Chevrolet Chevelle LS6 Convertible is rare in every sense of the word. The documented factory-production 13-second Chevelle LS6 is one of just 18 convertibles known to exist. Few were equipped with a 4-speed manual transmission. The ultimate Chevelle package occurred that year as a 450 HP worth of LS6 Turbo-Jet power to those willing to pay $263.30.
Fitting the car with LS6 required options that backed up all that power with heavy-duty engineering and added nearly $1,000 to the base price.
With a Holley 4-barrel carburetor, aluminum dual-plane intake manifold and dual exhaust, the LS6 engine was conservatively rated for 450 HP and 500 lb-ft of torque. The 454 was prepared by the factory with a forged crankshaft and pistons with 4-bolt mains. A high-performance camshaft with solid lifters worked dual-sprung oversized valves in the cast-iron heads.
The F41 suspension group packed heavy-duty coil springs, front and rear anti-sway bars, and box-welded rear lower control arms. The 6,500 RPM redline required deep-groove accessory pulleys. Power front disc brakes and power steering. The LS6 remains a legend to this day.
