If you are looking for a repair manual I would reccomend just getting a subscription to alldatadiy.com
I bet I have bought 50 haynes and chiltons manuals over the last 20 years, but they really don't compare to the alldata site. I have a subscription on all three of our cars.
If you are looking for just general motor books explaining modifications and builds, there are a few on Amazon.com. I have the one SHM put out and one other one I can't remember the exact titles right now. While most of the information is still valid, some of it is sort of outdated.
