|Engine||8cyl - 454L|
A beautifully restored 1970 Chevelle SS convertible with a LS6 that is just screaming to be taken out on the road! The 454 LS6 engine sounds incredibly healthy and was recently tuned in our dyno booth. The manual 4 speed paired with this toque monster of an engine makes this car a blast to drive, the convertible top is just an added cool factor when cruising in this Chevelle. The interior has been recently reupholstered along with new carpet and door panels. The saddle vinyl seats are incredibly comfortable and hold you in the car nicely when it takes off. The dash looks great with the original radio and premium factory gauges; tach, speedometer, temp, fuel, voltage and a clock. A Hurst shifter and center console finish off the interior nicely. The suspension has been rebuilt to factory specifications and rides extremely smooth. This Chevelle will pass everything but a gas station!
In 1970, sheetmetal revisions gave the bodies a more squared-up stance following the coke bottle styling, and interiors were also redesigned. The 1970 Chevelle shared many sheet metal body parts with the 1970 Buick Skylark GSX, both are GM automobiles and have interchangeable sheet metal. They are also the only two muscle cars to share the same roofline. The 1970 Chevelle came in sport coupe, sport sedan, convertible, four-door sedan, a couple of wagons, and coupe utility (the El Camino) body styles. Only three of these (Malibu sport coupe, Malibu convertible and El Camino pickup) were available with a choice of one of 2 SS options; RPO Z25 with the SS 396 (402 cid) engine and RPO Z15 with the new 454 cid engine. The base model was now simply called Chevelle in lieu of the former base 300 Deluxe, and was only available as a Sport Coupe or four-door sedan. The hardtop, convertible, and sedan received the upgraded sheetmetal but the station wagons and El Camino retained the previous year sheetmetal panels (which went on for the next 2 model years). New options included power door locks and a stalk-mounted wiper control. Production was expanded to the GM Arlington Assembly plant in Arlington, Texas (where the Chevelle was assembled with its corporate siblings in this case the Oldsmobile Cutlass).
Engine choices ranged from the standard 155 horsepower six-cylinder and 200-horsepower 307-cubic-inch V8, to a pair of 350 V8s and a pair of 402 engines. RPO Z25 SS equipment option included one of these 402 cid engines but was still marketed as a 396. The second 402 cid engine was available under RPO, rated at 330 hp with single exhaust, and was available in any V8 series except an SS optioned Malibu or El Camino. 1970 also saw the introduction of the 454 cid engine and was only available with the RPO Z15 SS Equipment option. The base 454 cu in (7.4 L) engine was rated at 360 bhp, which was also available with cowl induction; and the optional LS6 version equipped with a single 4-barrel 800 CFM Holley carburetor produced 450 bhp at 5600 rpm and 500 lbâ‹…ft at 3600 rpm of torque. There were 4,475 LS6 Chevelles produced.
