Reading many of the posts here is a great start. Some of these guys have played with these cars since they smelled new. Most are more than willing to answer questions, and there are quite a few that will do more than that, I have yet to find a definitive book about these cars, and will be watching for an answer here. Since you have already decided on a 70, start collecting photos of the real 70 Hemi Cudas that go up for sale. Most of the big dollar cars have been restored to the level where they can make pretty good references. Get a copy of the factory service manual (the DVDs are pretty good). Ask questions here about anything that seems unclear. Do some searches here about what to look for and look out for when buying a Cuda. Read some of the restoration threads. If (when) there are key photos missing from the thread- email a request for a copy to the author. Many of us love talking about these cars.
There is some invaluable info for the taking already here - more than you will ever learn from a book or two.
