Classifind Cut 57: 1968 Pontiac Firebird OHC6 Convertible – Sold?

Nov 2020 | Classifind Cut, Topless Thursday

December 2nd Update – We just confirmed the Craigslist ad for this ride expired and with no replacement listing found, we’re assuming this car sold.  This one may have got away, but if you have your heart set on something similar, email us the details of what you’re looking for or call Rudy directly at (908)295-7330.

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 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 drive train matches build code straight 6 overhead cam 3 speed (rare) very good condition.”

Would you promise to keep the original OHC6 in this Firebird?  Comment below and let us know!

    I had two OHC6 Pontiacs. My first was a 68 Tempest and my second was a 67 LeMans sport coupe. I took possession of the 67 12/24/79 exactly 13 years after the original owner took possession from Flatbush Pontiac 12/24/66. Both those cars served me well. While working at Alpine Pontiac in the 80’s I loved listening to “war stories” from the veteran Pontiac Techs who spun wrenches on Pontiacs their entire careers. One guy told me around 1970 they replaced an OHC6 with a Chevy I6 (under warranty) because GM couldn’t supply the engine any longer as it was now out of production. Boy do I have stories…..LOL

    BTY: The OHC6 would stay. The wheels and cloth seats would go. I keep my cars original as they rolled out of the dealer.


    A nice driver, leave as is!
