Books / Manuals

Personally, whenever I'm thinking of doing a project, the first step I take is to get a book on the topic and read through it. Granted, most of the books that I own aren't car-related, but I do find it very helpful to be able to sit down and read on the topic before I pick up any tools.  For example, when my starter died, I thought I was prepared to get the two mounting bolts out; had it not been for the book, I wouldn't have known that I needed a universal joint in order to reach the bolts.

Books by Carroll Smith

These books are dated--Carroll Smith wrote Prepare to Win back in 1975--and they're written for race folks working on race cars, but the principles are the same.  These books are dense with a LOT of information, but the author (Carroll Smith) is sprinkles quite a bit of humor as well.

Generic books

These books aren't specific to LS4s or even LS-Series cars, but they're good reads for those wanting to learn more.
