Where is the block's part # is stamped at???
 

Does anybody know where the factory stamp on the block is located that tells what kind of block it is and all of that stuff??

It is cast into the bottom of the block, in the back, either the right or left side(I forget)

I got a '69 351W and the part number is stamped on the bottom.

Stang_ROTY---Where exactly at on the bottom? I have a 69 Mustang but my car had a 302 2-bbl originally so I need to find out what year my engine is. I think it's either a 69 or 70. 69 was the best year for the windsor, wasn't it?
