Autoblog reports that General Motors has opened a blog that commemorates the 50th anniversary of the Chevy small block engine. There apparently are no other blogs at gmblogs.com—just a logo with no links. But the Smallblock Engine Blog is generating comments on all its posts, including corrections from the dedicated base of small block engine fans. The initial post, for example, offers a timeline of small block engine milestones. The one comment on the post: “The 350CID debuts in the 1967 SS Camaro, not the ‘68.”

Categories include “Historical Facts,” “GM Brass,” “Performance,” and “Photo Album.” Clearly a GM-sponsored site, it’s another intriguing use of blogs on a very targeted topic.
