sorry i ruined the post for you jerry i not making or keeping any friends today work on a dry block engine that had spacers under the mains but looked like they cut down some iron sleeves to fit in mains . were do you get the inserts ? just did a aluminum V8 engine on the old T/A line bore with powder metal caps was worried about the finish is was going to get . but the old flat top T/A did not let me down she really did very nice finish with the coated carbide lacey willams cutter on it
