I hope it will be helpful to let people know that the edition currently on sale still has all the information contained in the original version, so those older reviews still apply.

this is a very good book that has tricks of the trade that can be applied to any sohc or dohc motor out there. highly recommended for people that want to save money by not going the route where there is little to gain in terms of reliability or horsepower. straight and to the point.
