Best Slant 6 Reference Manual

Yes, but it's not a very good one. There are all sorts of bizarre errors in it - the book confuses some doctored "official" specs for NHRA stock class rules with the real production specs in several places, it claims the Lean Burn ignition used breaker points, and they often didn't check if particular performance parts were still being made before they printed the book. Plus, they often neglect good performance parts from non-MP sources. In essence, the book is intended as an advertisement for Mopar Performance parts.


I have a few of the Mopar engine books. They are a good read, but they are not the "bible". As Matt says, there are a lot of mistakes, and missinformation. They refer to parts that were available for the V-8's but never for the slant, and mods that are doable for a v-8 but don't yield results on a slant. The book can give you ideas, but use common sense, while reading.
PS: the older books are better then the newer ones.
Personal opinion, for info. Factory service manual for the year of the car/engine (parts manual nice but not required), the mopar performance book, and www.slantsix.org. Just remember the saying "the good thing about the web, is anyone can post. The bad thing is anyone can post". There is wrong info post all over the web on these engines, even on slantsix.org, but the people with first hand experiance, can generally, sort the valid info from the wrong info, in the post.
