I have a book "how to build max performance ford v-8s on a budget" written by George Reid. In about 3 different places he states the duration is a measurement of camshaft rotation, which is dead wrong, it is crankshaft rotation. There are other examples that I will not go into, but I am quite certain that this book is far from being a great book. He said that 1975 to 1984 castings were poor quality for both 5.0 and 351. Cracking is one issue. He also states that the Mexican blocks have wider mains and much more nickle in the iron. He claims they are a better block.

Any of you hear any of this before?
