25-Years-Owned 467-Powered 1968 Pontiac Firebird Convertible 4-Speed

Description

The Pontiac Firebird debuted in 1967 as Pontiac’s answer to the booming pony car market, joining the ranks of the Ford Mustang and Chevrolet Camaro. Built on GM’s F-body platform, the Firebird distinguished itself with aggressive styling, performance-oriented engineering, and a lineup of potent V8 engines. By 1968, the Firebird had refined its identity with subtle design updates, improved safety features, and a continued focus on delivering a thrilling driving experience.

The 1968 model year brought enhancements like a new front-end design, Astro Ventilation, and revised suspension geometry. Available in coupe and convertible configurations, the Firebird offered a range of trims and powertrains, from the inline-six to the high-performance 400 models. Its blend of unique style, muscle, and everyday usability made it a standout in the segment.

This 1968 Pontiac Firebird convertible has remained under current ownership since 2000 and is finished in metallic red over black vinyl with a black convertible top. Power is provided by a professionally built 467 cu-in Pontiac V8 mated to a Muncie M21 four-speed manual transmission and a 3.73 Positraction rear differential. While the owner notes that this Firebird is not an original 400, the factory interior remains. The car rides on an upgraded suspension and is fitted with a Flowmaster exhaust.
