i was just given a SBC and trying to find out what exactly it is. here is what i have found so far:

Block Casting: 3970010
also a tag right by the oil filter has: 6431811322 (this tag looks like it was applied to the block, not a casting or stamp)

Heads: 14014416

Intake: 340261

web research has come up with the following, but I'm curious about the number on the tag by the oil filter, I can't seem to find any info on it.

69-79 350cid Block with 80-86 305cid heads, manifold from 74-76 350cid with 4bbl.

can anyone offer any help with the tag number?

is this even worth the effort with what I got?
thanks
Rob

What's the tag made out of, and how is it attached? That's not a GM part number on it - maybe a rebulder's code. Got a photo? :thumbsup:
