A Rare Spec Survivor: 1967 Pontiac Firebird Convertible With the OHC Six

Pontiac built 82,560 Firebirds for the 1967 model year, yet the convertible body style accounted for just 15,528 of them. Narrow the field further to cars fitted with the overhead-cam six-cylinder engine and the number drops to a mere 2,641. That combination is what makes this particular example stand out, and it is now offered for sale out of Londonderry, New Hampshire with a $30,000 asking price and a clean title held in the seller’s name.

On the visual side, the cabin shows some fading but remains in solid overall condition. A period-correct Hurst shifter and console sit inside, paired with a 326 HO Muncie four-speed transmission. The convertible top is fresh and features a clear rear window, a detail worth noting since these plastic panels typically cloud and yellow with age. According to the seller, the bodywork was handled by a previous owner, who described the result as a “5 footer” rather than show quality.

The engine bay is where this Firebird gets interesting. The 250 cubic-inch (4.1-liter) overhead-cam inline-six was rated as high as 215 horsepower when equipped with a Quadrajet four-barrel carburetor. This car goes further with six-into-two cast-iron headers, a custom Sprint exhaust, an aluminum radiator, an SS flex fan, and an Edelbrock AVS2 four-barrel. A new alternator and a chrome four-barrel Sprint air cleaner round out the hardware, while the power booster and master cylinder have both been updated.

Braking and electrical items have clearly received attention too. All drum brake components and the front-to-rear lines are new, along with every emergency brake cable. The seller reports that the lights, horn, wipers, and turn signals all function. Two honest caveats are disclosed: the rear main seal or oil pan weeps after a drive, and the fuel gauge only works intermittently. The odometer reads 86,000 miles, though no claim is made that it has not rolled over.

Values for this specification reportedly span roughly $18,995 to $82,500 depending on condition and documentation, which makes the asking price worth a closer look for anyone hunting an unusual Pontiac. The overhead-cam six is a distinctly different proposition from the V8 cars most collectors chase, and with fewer than 3,000 built in this configuration, examples do not surface often. A thorough inspection before any money changes hands would be the sensible next step.
