Some great photo’s for reference, the 73 in the first picture has orange plug wires the other two do not, which is correct? I must also say through this whole post I never mentioned that I was working on a 74 B body. I am quite sure that many of these e body’s were the same. Engine is ready for paint and just thought that when assembling may as well put together properly. All the help so far has been great and will welcome anyone else’s input. Good to know there are a few people out interested in the 3’s and 4’s.
