The internet is a wealth of information but you can't take it with you everywhere. I'm going to the Portland swap meet in a couple of weeks (it's the largest on the west coast) and I'd like to take a book with me that had every possible chevy casting number (engines, heads, water pumps, muncies, rear ends.....ect.) so I can be positive of what I'm buying. There is a book out called "Chevy V8 casting numbers 1955-1993" which seems pretty good, but I don't know if that's the best one or not. Please give me your opinion. Thanks!!!!!
