help-understand Milleniums?

Wow! Nice!
To answer your question, you probably would have made some mistakes and learned via the school of hard knocks like I did. But that's how many of us learned before the world had a net to check and ask questions to.

My first book was the MP catolog followed by the engines book, chassis book and then "How to rebuild..." Book in which I built my first and current engine with. I can not keep all the specs in my head. So, for me, a book is great.
