First let me say that this web site is by far THE best for AD trucks and Stovebolt motors. Now that I've paid homage to Stovebolt there is another group of Inliners that would be helpful. Inliners International (inliners.org) devoted to all inline motors. They have a chapter in the DFW area and another in San Antonia. Though most of their Forum traffic is about the newer inline sixes most of the Inliners cut their teeth on stovebolts. You might also visit some of the local car shows, all you need to do is find a stovebolt and start asking questions. Hope this helps.
