I would but my connection is SLOW. It barely loads this page.
Anyway, off the block is GM 3970010. Years? 2 or 4 bolt or anything else you can tell me.
Heads say SN 30055 and the other SN 30061. TFS TW? G1? G2??
Thanks

 

3970010....302.....69....4...Z-28 Camaro
3970010....350...69-80...2 or 4

The heads don't even come close to any thing listed.

 

010 casting blocks are good high nickle content blocks and are worth keeping. Whenever I go looking for a 4" bore block to build a 350 I'll only grab 010 castings.
