1969 512 UNSTAMPED BLOCK
 

A 1969 factory untocuhed never stamoped 512 427 block March 69 dated. No decking, sanding,or any type of alteration 4 bolt main a 512 is nearly impossible to find like this due to the fact they were CE stamped. I have only seen a handful of post 1967 427 unstamped blocks. $10,000
