Suffix code

Okay folks, I just purchased a '69 427 4-bolt block. The early casting date is H-22-8. It is a short run 3955270 casting(6-8 weeks?) It was assembled in September and has a BL suffix code. I am not finding anything in my reference material for BL. I'm heading back to Michigan now and would appreciate any help. I can take and post pics once I get home tonight.
Thank You.
