Halted Hibernation: 1968 Pontiac Firebird Sprint OHC6 Convertible – NOW $19,750
April 3, 2021 Update – Coming across the first new listing in four months for this ’68 Firebird Sprint we first featured in November 2020 confirmed the current caretaker decided to store their overhead cam six powered Firebird convertible over the winter before trying to restart finding a buyer once warmer weather returned. We’re pleased to report the seller also lowered their asking price by $750 since then to the current $19,750. We sincerely hope the buyer appreciates this car for the rare engine it has and avoids the temptation to perform a V8 swap on it.
December 2, 2020 Update – We just confirmed the Craigslist ad for this ride expired, and with no replacement listing found, we’re assuming this car sold. We will keep an eye out for any updated listings for it.
It’s no secret Pontiac made some very powerful V8s over the years. Less remembered is the division’s overhead cam, inline-six engine used to power entry-level Tempests and Firebirds in the late sixties. Incorporating such innovations as a large aluminum valve cover, a fiberglass-reinforced timing belt, and an external jackshaft driving both the oil pump and distributor, many considered this engine advanced by Detroit engineering standards at the time. The Pontiac OHC 6 followed the Jeep Tornado inline-six as the second post-World War II domestic-developed and mass-produced overhead cam automobile engine.
Unfortunately, most cars factory-equipped with these engines had them swapped out with more powerful V8s. Luckily this driver quality, red-over-black 1968 Pontiac Firebird convertible originally featured in November 2020 and now relisted here on Craigslist in Chambersburg, Pennsylvania bucks that trend by still having its numbers-matching 250 cubic inch inline-six mated to a floor-shifted three-speed. There is no indication, however, this car is an even more desirable Sprint edition that offered slightly more power. Currently asking $20,500, the Collector Car Market Review Online Tool places the asking price between this guide’s current #3 “Good” estimate of $16,800 and it’s #2 “Very Good” appraisal of $25,000.
Here’s the seller’s brief description:
“1968 Firebird convertible sprint build code matches the car except for color. Overhead cam straight 6 with 3 speed manual transmission car had a restoration about 18 years ago been garaged ever since .”
