I don't think Edward has had any spare copies for a few years. As Paul says second hand, as well as TT put a wanted add here and on Homewoekshop. TT also has many build threads on the LS in all it's sizes so worth reading through those to see how others have done things
You could also track down the old issues of ME that the build was in though they are a bit more specific to just that engine where as the book gives alternative methods often using Edwards Fowler as an example.
