John, I answered on your other thread about the original 427 manuals. I'm still not sure if you're after the original owners manual or a particular brand's build manual, I found the old Contemporary build manuals really interesting. While some of it is obviously specific to the brand, there's some great general information as well.

Dimis - same here! The ERA website was pretty much ahead of its time years ago for having so much good information when others were still just posting information packs to interested punters. They have always been a class act.
