common rookie mistake
You are ignoring good advice.
Unless you measure the bores, you will not know what the block is.
End of story. Anything else is a fantasy.
No one has mentioned it yet, but 428's have an "A" or "C" sandscratch on the back of the block.

Hence, you cannot really rely on the books.

The Ford Motor Company in house O. S. I. (Obsolete Supercede Interchange) book is not sold to the public. It's an in-house book Ford publishes for dealer parts departments.
This book updates part numbers, tells if a part number is obsolete, and will give the user the true part number from a casting number.

I agree
I'm sure the OSI book is better than aftermarket books. All the books are likely to be incomplete though b/c of the day-to-day decisions that workers at the foundry's and assembly plants made to keep the lines moving.
In any case, its all just speculation until you measure the block.
To assume that your block is a 428 because two buddies have c6Ae-u heads on their 428's is just wishful thinking.
C6AE-U heads were the standard FE passenger car head in 1966. They were used on 352's, 390's, and 428's.
Racemaster33, if you decide to sell the block and/or heads, you need to have the facts right to be able to responsibly represent what you have, or at least tell people you don't know.
I may be violating a forum rule here, but you may also want to refer to the fordfe.com website. It has lots of folks who are absolutely the most knowledgeable FE experts in the world. I suggest you post a question about your mystery block on that site.

mystery block
Not to fear, before I do anything with the block I will take to a machine shop to be checked and have the bore measured while there. I woudn't dare advertise something if I wasn't sure of it, nor would I want to buy something that way.
The reason I came to the conclusion is because I've been working with a guy from the FE websight everybody talks about. Basically, he came to that conclusion.
Next week it will checked for cracks and bore checked and I'll share it with everybody. I doesn't matter to me if it's a 352 or 428 because I'm not going to use it myself. I just want to be able to tell the buyer exactly what it is and how I came to that conclusion.
Thanks
