Sprint build in Car Craft
The February 2020 issue of CC has a nice article titled “The Baby GTO” about a stock build on a 67 230 Sprint engine with a dyno test at the end. Historian Steve Magnante wrote the piece and he obviously has a good bit of knowledge as well as a soft spot for the cammer engine. Spoiler alert: The factory rating is not optimistic.
