www.fordification.com has block,crank and tranny numbers. Other good info also. There were a few pretty good sites that are gone now that had head numbers and others. Most of that should be listed in some of your books. The Steve Christ book and others are ok but do contain mistakes as most printed publications. Your very best bet would be a master part catalogs. These are $99 and available on CD rom. If you can post the numbers of the stuff you need to ID I can help ya out. Block castings are the most confusing and misunderstood. Most FE/FT block casting numbers are generic meaning the same number was used on many differnet bore blocks. Some blocks do use a certain number for a specific application so some casting block numbers are easily id-able. Some blocks don't even have a casting number period. For those and others some drill bits and carefull measuring will tell you whats what. The main reason being Ford chose to vary what cyl wall cores were cast into a paticular run of blocks. Also cranksaddle webbing a factor also. It depended on what the foundry needed to pour for production. Some of the later 70's era D2,3,4 blocks were treated to nodular maincaps Most FE/FT's got the basic grey iron version. The 427's for the most part got nodular caps but some did have grey iron caps. 428's had both also. I have most part and casting numbers available if you need any help. Let me know.
