Can you take a normal valve body out of a Turbo 350 and convert it to a full manual? What is the difference in the two? On ebay I saw a guy selling them for $50.00. Most of the ones I have seen go for $150.00. That is telling me that a stock valve body can be reworked. Of course I could be 100% wrong. He may just have a foundry and machine shop CNC mills in his backyard.
