I have it, its a pretty good read, but it is geared a bit towards your old pushrod V8 type basic engines, still a nice read with a good bit of info in it, are you looking for an engine book in particular, or tuning and building?
This^^ Book is also an excellent read, full of useful info, he has done a book on forced induction too but its going for sill amounts of money now. I have one or 2 also by David Vizard,
another pretty good one but again focused more on big American V8s, he's also flow bench obsessed!
