SIA Flashback – 1967 Pontiac Firebird Sprint: OHC from John Z’s PMD

Pontiacs have often had a reputation for going their own way and bucking GM corporate dictum, and few things illustrate this trend more than the overhead-camshaft six-cylinder engine that John Z. DeLorean and crew developed for the LeMans and Firebird. For SIA #150, November 1995, Kit Foster took a rather in-depth look at the development of and innovations included in that engine, as framed by a 1967 Pontiac Firebird Sprint convertible.
