427 Block

I acquired a 427 block back in the mid 80's and its been sitting up for all these years on a stand in my shed.

After reading the many posts on this Forum I decided to try and confirm what I have. Any assistance would be appreciated. The following is the info I have from the block:

1. Driver side;

3B22:3
DIFF

(I believe this is the date code 22 Feb 1963 but I don't know what the ":3 or DIF stands for)

2. Passanger side;

HP 31 (HP=High Perf but what is 31?)
55 (sideways over the #'sbelow)
C3AE (1963 Ford Engr)
6015AB (?? I thought blocks were 6010?)

3. In lifter Gallery;

HP 24 ("24" is sideways after HP with 1 dot behind "24")

4. Where trans mounts to block;

23
HP

5. Crank has the following #'s on it;

C4AE (one dot) B
9

6. Bore of cyl measures 4.28 (Is this punched too far for viable use? I believe the original bore was 4.23.)

7. Cyl wall thickness bet/ cyl is .3125

8. It appears to be a "Top Oiler" due to oil pressure relief valve just above cam bearing bore.

9. In addition I have a dual quad intake that reads;

C3AE-9425-K
3LC (Is this the date code?)

Thanks for the help. You guys a great source of info.
