Have any of you guys had your tb bored over size? I am just wondering how much bigger I can go with it. I saw on Howells site that they go to 55 mm or so, but the jeep tb everyone is using is like 60-62 mm. I'm concerned about going to big with it an breaking into the casting. I own a machine shop so if I can get this worked out I'm planning to sell some of these. Any help would be great.
