305 engine suffix code

[mjgord51]

I have this eng. 5.0L already in truck and its a little hard to get the Casting #'s but here's what I could get from area of casting #'s. Also I cant find what the suffix code is other then the letters coming up as a Big Block, Its a small block & not a big block. With out the Casting #'s I am not for sure if it is some kind of a special engine or something like that, Here's some pic's to look at guys. Oh I'm sorry my Male Chauvinist side is showing through, AND "Gals" if applicable. I would like to know more then I know so far about it, Any help would be great, Thanks, mjgord51
