Posted May 7, 20231 yr comment_653404 I had a Pontiac GTO in my early days and knew several guys with Firebirds. I'd heard of the Pontiac Sprint 6 but never knew much about it. Found this article today. It's an OHC but the cam is in the valve cover. Pretty crazy. It was a big engine too. 250 CI versus 146 for an L24. Straight six with a Quadrajet. https://www.hemmings.com/stories/article/inside-the-sprint-six Link to comment https://www.classiczcars.com/forums/topic/68323-other-early-ohc-straight-sixes/ Share on other sites More sharing options...
