Not Ranked
Yep, I know it's hard to believe, but there was very little rhyme or reason to casting numbers because there were exceptions to every rule. You simply can not make a blanket statement about casting numbers other than that you can not rely on casting numbers. But if it's an unmolested 427 block, even in "rough" form, it's a very nice find.
