Engine swap

i'm gonna try to replace the engine in my '91 s-10 blazer 4x4 myself. it is a 4.3 and i am going back with a 4.3. what manual/manuals would y'all suggest?

Chiltons is what my Uncle recommended. But if your in need of detailed photos of each step in the process the Chiltons wouldnt be for you. It should be no prob in my opinion following the step by step text instructions from Chiltons and from time to time if your stuck use the internet forums/or one of the free online auto manual sites....
