Hi all . im new here. And i'd like any advice on this? Im looking at buying a 68 440 block . But it has a bit of a mess on id pad at the starter opening. 1 picture is my drawing of what cant be well read on actual block. 2 numbers are the same. The one is X'd out. the other is not X'd out but in different font style of punch. These 2 same numbers are (2390) one day before the date that is stamped on the top engine id pad , next to distributor D 440 (1968) 2 13 (february 13) The second X'd out number is february 1st 2379. I got dates from maxwedge.com converter. I have a few theories. Lol. Stupid criminal.? An apprentice at factory screwed up 1st number and tried to " squeeze" in the correct number afterwards? Cause it seems the same punch size and font? Or, Later one guy decided to make it very clear which of the 2 originals was correct.? What do you guys think? What could have happened here? Would any of you buy a block like this?
