Brent,
over at Webrodder.com, Doc has a number of articles on building/rebuilding a 390. He does it in three different versions - Stock - Mild and Go for It
http://www.webrodder.com
I found it very helpful in my bored/stroked 431 build.
If you are unable to find the articles mentioned, I think I have links to them on my site,
http://www,3x2csx.com. If not, I know I have the old Hot Rod article, the Edelbrock article, Doc's three articles and the original oiling modifications article.
