The biggest, baddest muscle car convertible is the Chevelle SS 454 with the over-the-top LS6 454 cubic inch, 450hp engine and a four-speed manual transmission. People can talk about Mopar Hemis and Ford 429s but nothing held a candle to the LS6 and the shear audacity, unruliness and meanness of the concept and its execution.

Convertibles are supposed to be for cruising around on summer evenings, for stylin’ and making runs to the ice cream store. The LS6 Chevelle is so rude and macho it’s not family friendly. It’s at least ‘R’ rated. Moms do not let their daughters date LS6 Chevelle convertible owners.

Which is exactly their appeal.

Chevrolet had developed the muscle car concept probably as far as any of the American manufacturers took it. They not only had big block engines (the 348 and 409) very early but thrived on the mid-sized line, the Chevelle, which fitted Chevy’s image and entry-level market position. That meant plenty of cars, plenty of units and plenty of opportunity to spread the overhead and development cost of engines, transmissions, drivetrains and suspensions that spread its performance halo across the bread-and-butter Chevelles that paid the bills.

Chevrolet’s enthusiast management team also recognized that a few outrageous muscle cars established an image that paid as many dividends in sales as racing wins did. There again, the LS6 Chevelle convertible drove home the message like a two-pound hammer. Cars like the LS6 convertible being driven on the streets and drag strips sent the message that Chevys were cool.

After being overlooked for many years LS6 convertibles have recently brought a great deal of attention and recognition for their style, performance and rarity. Only 4,475 LS6 Chevelles were built, including both hardtops and convertibles. It is the high point in Chevrolet muscle car performance. Next year, 1971, insurance considerations and emission controls began to eat into the horsepower and performance of all muscle cars. The LS6 disappeared.

The 1970 Chevelle SS 454 LS6 convertible offered here is beautifully presented in better than showroom condition. In addition to the mega-powerful 454 cubic inch 450hp LS6 it has an M22 close ratio, heavy duty 4-speed manual transmission with Hurst shifter, power steering, power front disc brakes, power top, tilt steering wheel and bucket seats without a console. It is fitted with Rally II wheels wearing Goodyear Polyglas F70-14 white letter tires. The engine has its full complement of correct smog equipment.

Unfortunately it has essentially no documentation. There is an old-appearing New Vehicle Warranty and Owner Protection Plan booklet. The name hand written on the booklet matches the name on the Protect-O-Plate which is exceptionally shiny, pristine and unmarked. The Protect-O-Plate references the T1005CRV number visible on the block and there is a VIN stamped on the side of the block near the clutch linkage that is photographed on a display plaque with the car but is not readable in the car.

At the time of cataloging no paper trail has been found showing when, where or from whom this Chevelle was acquired or relating to its restoration, which is of the highest quality. The cowl tag is consistent with this Chevelle’s equipment and presentation, but indicates a build date in the first week of October, a date which is only barely compatible with the October 5 build date for the engine and the assembly plant location in Baltimore.

This is a beautifully restored, presented and maintained 1970 Chevelle SS convertible, a gorgeous piece in Fathom Blue with Black stripes, Black vinyl interior and Black vinyl top. It is the most powerful and exciting of all convertible muscle cars.
