Re: 3969854 block question
Guys!
 Another question to add to the pile: Shouldn't the hyphen between the day & year actually be a screw head? See these images I just dug up.  This is another '854 block:  A '512 block:  Steve

Re: 3969854 block question
Oh - wait a second!
I just realized ( duh ) that the year went to two numbers so what do you think the odds are that someone just ground off the 0 -or- 1 and redimpled the block in this area?  Steve

Re: 3969854 block question
It's a 4 bolt block and they were only made the first year so there would have never been a 70-71-72 cast into it,only a 9 or 69,,,,i think!

Re: 3969854 block question
The picture of the casting date of D-7-7, there looks like the remainders of a '0' after the last '7'. I think someone ground off the '0' in the 70 date code.
