1970 Chevrolet Chevelle SS LS6

LMC is very proud to offer for sale this 1970 Chevrolet Chevelle SS LS6

  This 1970 Chevrolet Chevelle SS 454 LS6 is one of the most sought-after Chevrolet muscle cars, with its world-beating LS6 big-block V-8 engine. Until 1970 the most powerful engine associated with the Chevelle SS, aside from the 427-powered COPO specials, measured 396 CI of displacement, which Chevrolet devotees were forced to wield against such over-the-top powerplants as Ford’s race-bred Cobra Jet and Chrysler’s brutish 426 Hemi. Overmatched for years across its divisional spectrum thanks to a self-imposed limit of 400 CI in all intermediate models, General Motors management finally realized the decision was hitting the company on the bottom line, and in 1970, GM relented, dropping the restriction on displacement and unleashing a deluge of big-block muscle led by the LS6-powered Chevelle. Chevrolet engineers pulled no punches in assembling the LS6 engine package; they began with a reinforced cast-iron block and added a forged steel crank and connecting rods, forged aluminum 11.25:1 pistons, high-flow closed-chamber rectangular-port heads, a high-duration high-lift mechanical-lifter camshaft and topped it off with an 800 CFM Holley 4-barrel carburetor on an aluminum intake manifold and fitting deep-groove pulleys to retain the drive belts under high-speed operation. Rated at 450 HP at 5,600 RPM, the LS6 revved freely and delivered increasing power right up to its 6,500 RPM redline.

  Built at the Arlington, Texas, assembly plant, this Cortez Silver LS6 Chevelle is a striking example of the breed that features the highly sought-after 454/450hp, original distributor, pulleys and radiator, correct 4150 Holley 4-barrel carburetor and correct dual exhaust with resonators. The original LS6 automatic transmission is joined to the original 12-bolt Positraction rear end with 4.10:1 gears. In addition to its Strato bucket-seat interior with center console, this superbly restored LS6 offers power steering and front disc brakes, heavy-duty suspension with front and rear sway bars,  Soft Ray-tinted glass, a sport steering wheel and an AM radio.

  It is documented with its Shipping Invoice, listed in the LS6 Registry and complete with Chris White's inspection as well as Jerry Macneish's Hi Performance Inspection.
