MN 427 block
 

Were there any service replacement MN coded blocks produced into the 1970 model year? I'm guessing this one is a restamp but thought I'd post here as FYI.

Tony, I looked over that ad & believe it's description and the pics are for different engines? One does not match the other. Did you inquire to the owner & learn otherwise? My reason:No casting date shown in pics & of course, if it were a CE block, it would show such on the pad. This block is clearly not a CE, but, as seen, shows MN. My limited expertise on stamps, IMO, this a real deal.
