Story
1968 Chevrolet Impala SS427
For 1968, the Impala SS427 moved from the cleaner 1967 standalone-model story into a trickier option-code story. Checked references agree that Chevrolet no longer treated the SS427 as a separate model, but the RPO Z24 SS427 package still carried the big-block full-size performance path. Over-Drive lists RPO L36 427 CID 385 HP as standard with the RPO Z24 SS427 package, with four-speed or Turbo Hydra-Matic availability, and it treats the L72 427/425 as a special-order manual-transmission path.
That ordering complexity matters because 1968 Z03 Super Sport and Z24 SS427 claims can overlap without meaning the same thing. Some sources present Z24 as delivering bucket seats and console; another checked public reference reports that 1968 SS427 cars could be ordered without Z03, meaning SS427 equipment but without the bucket-seat, SS-door-panel, and console package. This page therefore keeps the public story clear: an SS427 visual package is important context, but an individual car still needs build paperwork, cowl/body evidence, engine suffixes, transmission tags, rear-axle codes, and paint/trim records before it should be treated as a documented factory Z24 car.
The baseline record centers on the L36 Turbo-Jet 427 at 385 hp and 460 lb-ft. It also notes the L72 special-order path without making every SS427 an L72 car. Reported production is held as a reported public count of 1,778 Z24 cars, while broader 1968 Impala or Impala SS totals are intentionally labeled as broader context instead of exact SS427 body-style splits.
