“The golden era of the muscle car was still going strong and 1970 will forever represent the most powerful, factory built, carbureted engines ever to reign on the streets of America. Chevrolet’s Chevelle has always been a perfect example from that era with its aggressive yet sleek design. Starting in 1964 and continuing through 1978, the Chevelle quickly became one of Chevrolet’s most successful nameplates and remains a highly sought-after and collectible muscle car with many engine options available along with its well-known Super Sport trim package.

The highest powered Chevelle model, and the only production GM car to have a higher horsepower rating than the Corvette, was the limited production 1970 Chevrolet Chevelle SS 454 LS6 model. This specialty Chevelle was only produced for one year with large rectangular port heads, high rise aluminum intake, Holley carburetor, solid-lifter camshaft, and higher compression at 11.25:1. Buying one of these impressive Chevelles meant the customer also had to purchase the mandatory SS454 package which included engine accents & SS fender emblems, black dash with round dial gauges with SS steering wheel, dual exhaust with twin rectangular tips, blacked out grille, wheel opening moldings, power front disc brakes, special performance suspension and F70 x 14 tires on 5-spoke 7″” wide sport wheels. The rear bumper featured a black insert with SS emblem, and a “”power bulge”” domed hood up front.

The St. Louis Car Museum is very proud to offer this 1970 Chevrolet Chevelle LS6 Hardtop finished in beautiful Fathom Blue with White Stripes and a Black vinyl SS interior. Powered by its namesake LS6 numbers matching “”CRR”” stamped 454ci V8 engine with a high flow Holley four-barrel carburetor bolted to an aluminum GM intake manifold that produces a beastly 450 horsepower and 500 lbs.-ft of torque! All that power is mated to an Automatic 3-speed Turbo-Hydramatic 400 transmission and a Posi-traction 12-bolt rear end. This Chevelle also features power steering, functional cowl induction hood, F41 Performance Suspension with stiffer springs along with front & rear sway bars, driver side mirror, bench seating, F70x14 white letter Firestone tires, AM/FM radio, with standard manual windows & door locks.

This Chevelle was originally ordered and delivered new from Jim Rathmann Chevrolet-Cadillac in Melbourne, FL before later traveling to Connecticut and ultimately into a collection based in Kennett Square, PA since January 2016. According to an original build sheet, our LS6 was born at the Lakewood Plant in Atlanta, GA and now shows 92,841 miles on the odometer. Complete with production build sheet showing its original (28-28) Fathom Blue factory color, (D88) Hood & Deck Stripe, (F41) performance suspension, (C56) instrument panel side vent, (GW8) 4.10 axle ratio, (G80) Posi-traction, (JL2) power disc brakes, (M40) 3-speed TH400 auto transmission, (PL4) F70-14 white letter tires, (T60) heavy duty battery, (U63) pushbutton radio, (U80) rear speaker, (U27) glove compartment lamp, (Z15) 454 SS package, (ZL2) special induction hood.

After its arrival at our museum in March 2023, it received new sway bar links, spark plugs, fuel sending unit, blower fan resistor, along with topping off all the fluids to assure this very special Chevelle is in full working condition and ready to tear up the streets cruising to your local car show. We appreciate your interest in this very special 1970 Chevelle SS 454 LS6 Hardtop. Only 4,475 LS6-equipped units were produced in both hardtop and convertible form combined, making up less than 8% of the total Chevelle Super Sports built for 1970! Very rare indeed!

  • I see that the shifter is on the column. Didn’t all true SS’s automatics, especially the 454’s come with the horseshoe shifter in the console?

    • On the contrary, bucket seats and consoles were still optional on all Super Sport Chevelles in 1970. Same could be said for cowl induction hoods, even on LS6 equipped cars. Not all are the same. You would find column shift cars very common in the Buick GS line up, as well as most large displacement MOPARs of the same generation.
