thunderbolt:
This is just info from a photo copy of a BB ford book. It states thats the casting #'s are to the best of there knowledge and to measure when in doubt. I do not have alot of exp. with bb ford. I have just bought A 429 and I wanted to know what year it was, so I aquired those casting #'s from a book.
On a side note: I bought a 76 lincon 460. The heads were supposed to be D4(75-78), but they were D3(73-74), 5 less cc. You never know what they do with left over parts at the factory.
