This 1970 Chevrolet Chevelle SS sport coupe left the factory equipped with a 454ci V8, and work following the seller’s 2019 acquisition involved installing a 540ci V8, a replacement Muncie M22 four-speed manual transmission, and a Quick Performance rear end with an Eaton differential. Engine components include a forged crankshaft and pistons, Air Flow Research cylinder heads, a Holley carburetor, and a Griffin radiator. The car also has QA1 suspension components, adjustable coilovers, Wilwood six-piston brake calipers, a Hurst line lock system, Magnum 500-style wheels, and a dual exhaust system with Lemons headers and Pypes electric cutouts. The interior houses bucket seats trimmed in Ivory vinyl, Dakota Digital instrumentation, and a retro-style head unit linked to a trunk-mounted amplifier and subwoofer. This Chevelle SS is now offered with a build sheet, refurbishment records, the removed 454ci V8 and removed rear axle.
