The Chevelle’s upgraded by Yenko included a super sport blackout grille, super sport hood, 12 bolt differential, a L72 425 horsepower 427 engine with either a four-speed manual or a TH400 automatic, and optional body stripes. Of the 99 built, 55 had a four-speed manual transmission, bench seat and standard steering. Six of these had a vinyl roof. Thirty-seven more were TH400 automatics with power steering, rear radio antenna and a vinyl top. One automatic transmission car had no vinyl top.
