Power was everything in the era of the musclecar. It started innocently enough when some of Detroit’s car builders started building V-8 engines that topped over 200 horsepower. Three hundred horsepower didn’t seem like such a stretch, but when horsepower levels reached 400 and beyond, the world was a different place. These were cars that had neck snapping speed and could produce amazing quarter mile times straight from the showroom floor. There were many, but the absolute pinnacle was reached in 1970 when Chevrolet produced the Chevelle SS with the RPO Z15 package that featured the LS6 engine option. What one got when they checked the RPO Z15 option was a well-adorned Chevelle and the further choice of the LS6 engine that added another $263.30 to the bottom line. The LS6 was a monster 454 cubic-inch V-8 with 450 horsepower that was capable of eating anything else alive. It was not a car for the faint of heart and its sheer power meant many LS6 optioned Chevelles found a telephone pole or tree just as easily as they found the finish line. Their astounding power translated to a very low survival rate and perhaps that’s what makes these so special.
The LS6 equipped Chevelle SS was the King of the Friday night street fights as nothing else came close. Not only was the LS6 built for power, but it was also built with almost bullet-proof durability. An aluminum intake manifold served as the foundation for a massive Holley 800-cfm four-barrel carburetor. A forged steel crankshaft was held in place with four-bolt mains. An impressive 11.25:1 compression ratio demanded the best gas; something the Chevelle SS with the LS6 option had no trouble gulping at regular intervals.
The current vendor spent considerable time and was extremely patient in his quest to acquire a great LS6. The requirements were simple - a documented car with its original engine and desirable options. The example selected met the criteria. Finished in Chevrolet’s Forest Green, it had just 29,878 believed actual miles from new and retained its original numbers matching engine prior to its ensuing restoration. Most important is the presence of the original factory build sheet that clearly displays the LS6 option and the work performed was done so with this as a guide. The sheet metal is excellent and the engine compartment has been restored to show level right down to correct hose clamps with factory correct hoses.
Factory colors are authentically finished and this Chevelle was restored with all factory markings faithfully applied in all the right places. Power reaches the rear wheels through the most coveted manual M22 “Rock Crusher” transmission and the rear is equipped with 4:10 gears. This Chevelle rides on Firestone Wide Oval tires that are mounted on correct Chevrolet Rally rims. The interior features a bench seat and, as with all Chevelles that were ordered with the RPO Z15 option, the standard gauges were replaced with Chevrolet’s all-new Monte Carlo gauge set. The large flat panel held three round pods for the speedometer, tachometer, and clock. The 1970s are also alive and well in this Chevelle thanks to its factory AM/FM radio 8-track tape player. The black vinyl upholstery presents as new and all glass is clean and clear.
In addition to the aforementioned factory original build sheet, the car comes with its NCRS Shipping Data Report and also its certificate of registration in the LS6 registry. The Chevelle SS with the LS6 option represents the absolute pinnacle of classic American muscle. Built for speed and brute horsepower, it proved to be the dominating car both on the street and the track. Never before had anything so powerful come from Detroit and it remains today a legend. Fully documented and complete with original numbers matching engine, four-speed transmission and 4:10 rear end, it possesses the ultimate drivetrain, ticks the boxes of desirability, value and options and represents a fine opportunity to acquire one of the most powerful cars ever built in the era.
