This 3rd edition of the bible for all A-series engines was completed in 1999. The latest and great from David Vizard. This book has tremendous updates since the last edition! If you want to know how to get more power, how to get more reliability, or just how to get better gas mileage, this book will tell you how. Well illustrated and backed up with extensive dyno tuning. A must for anyone contemplating rebuilding an engine.
