Need Chevelle 12 bolt decoding
So I know it is a 70-72 Chevelle 12 bolt by the casting # 3969278 NF
I want to know what year...
Axle stamp is CKD 0619B2 (is it 06/19/70? or 71? 72?)
From rear on passenger side web is cast F30
Thanks,
Jason

Thanks! The original 350 is in it so I'm guessing it's a 4 bolt based on the 350-4?

I think they mean four barrel. It is very possible that it is a two bolt. Are the last three digits of the casting number 010 if so they are good blocks and pretty common.
