This Chevelle wears Medium Garnet Red, one of the meanest factory colors Chevrolet ever put on a mid-size car, and backs it up with a genuine SS 396 four-speed combination that most 1966 buyers didn’t actually order. Chevrolet built three different versions of that 396 engine, and nearly a third of buyers paid extra for the hottest one. Of the 72,272 SS 396s built that year, the overwhelming majority left the factory with an automatic. Here’s why a real stick-shift 396 deserves a second look.
