While the Chevelle was originally designed to provide solid, basic transportation, the secret was in the Chevrolet order form. With the right check marks and a few extra dollars, it was possible to order a car that would rule both street and strip. By 1970, GM had finally taken the corporate limitations restricting the size of engine they would allow to be stuffed into a mid-size body, and the result was a very special motor for the Chevelle SS. The Chevelle offered high performance with timeless good looks and remains a true collector favorite today.
The ultimate Chevrolet motor that would be equipped was the 454 LS6 which was conservatively rated at 450 horsepower. The 454 cubic inch Chevy big-block featured an 800cfm Holley four-barrel carburetor on an aluminum manifold atop solid lifters, forged aluminum high compression pistons, rectangle port cylinder heads, four-bolt mains, forged steel crank and connecting rods, and deep-groove accessory pullies. A $147 throttle-operated cowl induction hood ensured it never had to pant for air. Hi-test gasoline was mandatory with an 11.25:1 compression ratio, but the resulting performance in a 3,800 lb. car was pretty hi-test, too. The LS6 option added more than $1,000 to the base $3,800 price, but when the time came to step lively off the line it was worth every penny.
This 1970 Chevelle SS was fortunate enough to have been factory built with the numbers matching LS6 big block. Exterior is presented in the factory correct classic white paint with two black stripes that race up the cowl induction hood. Two authentic build sheets indicate that this Chevelle was well optioned. High-performance options include a Muncie M22 “Rock Crusher” four-speed, F-41 performance suspension and a 4.10:1 rear axle with positraction. This Chevelle was ordered by Berger Chevrolet in Grand Rapids, Michigan. Starting late in 1968, Berger Chevrolet opened a high performance parts department. Over the next five years, Berger became the number one Chevrolet high performance parts outlet in the United States. This timeline was during the Vietnam conflict and soldiers would write to Berger Chevrolet about their desire to built a “hot car” upon returning home. So it was decided that the dealership should specialize in selling the parts they would need for their builds.
This Chevelle SS has been through a complete ground up restoration and the end result is a stunning Chevelle that looks fresh off the showroom floor. With the exception of a steering wheel showing cracks in two places, the interior is in essentially like-new condition. Though the car comes equipped with factory gauges including an in-dash tachometer, it has been fitted with an aftermarket oil gauge under the dash. The engine compartment has benefited from show quality detailing. The block was refinished in Chevy orange and the intake manifold in natural aluminum color, while the inner fenders, firewall and radiator support wear a coat of satin black, all set off by fresh show-quality chrome on the rocker covers. There is a full complement of correct factory-style paint and crayon markings on the firewall, engine, master cylinder and steering box (among other places) and the serial number of the vehicle is stamped into the front engine pad. Treating the car to a trip up the hoist reveals a high level of detailing on the undercarriage, as well. The suspension components have been refinished yet show the type of paint markings that would have been applied at the factory during the original build. The floor pans show a dusting of white overspray, again very authentic, and the exhaust appears to be brand new from engine to tailpipe.
Great documentation including two build sheets, part number summary page and partial tank sticker are included with the vehicle. To many people the LS6 was and remains the ultimate muscle car, combining stylish looks, taut suspension and unprecedented power in one very impressive package. It was so good that it raised the unavoidable question of “what do we do next?”
