Don't believe there is such a book. Mustangs came in too many variations and models to write a complete book coverign everything though its been discussed a few times 
In general I would suggest in order, MCA Rule book, subscription to Mustang Monthly then run your final choices through this forum. And remember please do not believe everything you see on resotred cars, in print or in pictures. But they are normally a great start
In general terms a Sport Sprint engine is not detailed that much differently that any other engine that year
