This is a good book...

There is no better site in the world than here. Barry (who wrote the book suggested) and many other knowledgable and experienced FE builders are regular contributors.

That site is ok but I did once ask for guy's to post about their 390 buildups and got stupid or one-word answers. Unfortunately it seems to be a problem with yanks generally. One guy started telling me about engines like I was born yesterday. I ended up telling him to shut the f**k up.
Still, there are some seriously knowledgeable guys on there and if you scan around you can find some good stuff.
