Chevrolet Chevelle 300-1966 images

In 1966, most Chevelle shoppers who wanted power bought a Malibu or the newly standalone SS-396 — the base 300 series was built for buyers who wanted a car, not a statement. Of the 28,600 base 300s Chevrolet built that year, only 5,300 came with the optional V8, making a V8-powered example like this one the exception rather than the rule.

The cheapest Chevelle you could buy in 1966 was not built to turn heads — it was built to move families and sell in volume, and it did exactly that while its flashier sibling grabbed all the attention. That same year, Chevrolet gave the entire Chevelle line a dramatic redesign and let the Super Sport become a true standalone muscle car for the first time. The base 300 series got almost none of that spotlight. But buried in its spec sheet is a detail that shows how rare a V8-powered example like the one pictured here actually is.

1966 Was the Year the Chevelle Grew Teeth

For 1966, Chevrolet gave the entire Chevelle lineup a full body redesign — front fenders that protruded forward, new contour lines, a fresh rear cove treatment, and a wider-looking aluminum grille. It is also the year the Super Sport split off into its own SS-396 model with real muscle car credentials, sitting above a lineup that ran from the base 300 up through the 300 Deluxe and Malibu.

A V8 Was the Exception, Not the Rule, in the Base 300

The 300 series came standard with a 192-cubic-inch six-cylinder making 120 horsepower through a Rochester one-barrel carburetor and hydraulic valve lifters — the choice most buyers made. Chevrolet built 28,600 base 300s that year, but only 5,300 left the factory with the optional 283-cubic-inch V8, making V8-equipped 300s meaningfully rarer than their Malibu and SS-396 siblings. Stepping up to the 300 Deluxe added bodyside moldings, rear fender nameplates, and painted rear quarter reveal moldings; Chevrolet sold roughly 37,500 of those. Pricing started around $2,175 for the two-door and $2,200 for the four-door, on a shared 115-inch wheelbase. Because so few survive in original V8 configuration, values for a documented, numbers-matching 283-powered 300 have climbed well past what its humble spot in the 1966 lineup would ever have suggested at the time.
